When clang compiles a source file with ``-fcoverage-mapping``, it + generates the mapping information that describes the mapping between the + source ranges and the profiling instrumentation counters. + This information gets embedded into the LLVM IR and conveniently + ends up in the final executable file when the program is linked. + +2. It is also used by *llvm-cov* - the mapping information is extracted from an + object file and is used to associate the execution counts (the values of the + profile instrumentation counters), and the source ranges in a file. + After that, the tool is able to generate various code coverage reports + for the program. + +The coverage mapping format aims to be a "universal format" that would be +suitable for usage by any frontend, and not just by Clang. It also aims to +provide the frontend the possibility of generating the minimal coverage mapping +data in order to reduce the size of the IR and object files - for example, +instead of emitting mapping information for each statement in a function, the +frontend is allowed to group the statements with the same execution count into +regions of code, and emit the mapping information only for those regions. + +Advanced Concepts +================= + +The remainder of this guide is meant to give you insight into the way the +coverage mapping format works. + +The coverage mapping format operates on a per-function level as the +profile instrumentation counters are associated with a specific function. +For each function that requires code coverage, the frontend has to create +coverage mapping data that can map between the source code ranges and +the profile instrumentation counters for that function. + +Mapping Region +-------------- + +The function's coverage mapping data contains an array of mapping regions. +A mapping region stores the `source code range`_ that is covered by this region, +the `file id `_, the `coverage mapping counter`_ and +the region's kind. +There are several kinds of mapping regions: + +* Code regions associate portions of source code and `coverage mapping + counters`_. They make up the majority of the mapping regions. They are used + by the code coverage tool to compute the execution counts for lines, + highlight the regions of code that were never executed, and to obtain + the various code coverage statistics for a function. + For example: + + :raw-html:`
int main(int argc, const char *argv[]) {     // Code Region from 1:40 to 9:2
+                                              
+    if (argc > 1) {                            // Code Region from 3:17 to 5:4
+      printf("%s\n", argv[1]);              
+    } else {                                   // Code Region from 5:10 to 7:4
+      printf("\n");                         
+    }                                         
+    return 0;                                 
+  }
+
` +* Skipped regions are used to represent source ranges that were skipped + by Clang's preprocessor. They don't associate with + `coverage mapping counters`_, as the frontend knows that they are never + executed. They are used by the code coverage tool to mark the skipped lines + inside a function as non-code lines that don't have execution counts. + For example: + + :raw-html:`
int main() {                // Code Region from 1:12 to 6:2
+  #ifdef DEBUG                // Skipped Region from 2:1 to 4:2
+    printf("Hello world"); 
+  #endif                     
+    return 0;                
+  }
+
` +* Expansion regions are used to represent Clang's macro expansions. They + have an additional property - *expanded file id*. This property can be + used by the code coverage tool to find the mapping regions that are created + as a result of this macro expansion, by checking if their file id matches the + expanded file id. They don't associate with `coverage mapping counters`_, + as the code coverage tool can determine the execution count for this region + by looking up the execution count of the first region with a corresponding + file id. + For example: + + :raw-html:`
int func(int x) {

` + +.. _coverage mapping counter: +.. _coverage mapping counters: + +Counter: +^^^^^^^^ + +A coverage mapping counter can represents a reference to the profile +instrumentation counter. The execution count for a region with such counter +is determined by looking up the value of the corresponding profile +instrumentation counter. + +It can also represent a binary arithmetical expression that operates on +coverage mapping counters or other expressions. +The execution count for a region with an expression counter is determined by +evaluating the expression's arguments and then adding them together or +subtracting them from one another. +In the example below, a subtraction expression is used to compute the execution +count for the compound statement that follows the *else* keyword: + +:raw-html:`
int main(int argc, const char *argv[]) {    // Region's counter is a reference to the profile counter #0
+                                           
+  if (argc > 1) {                           // Region's counter is a reference to the profile counter #1
+    printf("%s\n", argv[1]);                
+  } else {                                  // Region's counter is an expression (reference to the profile counter #0 - reference to the profile counter #1)
+    printf("\n");                        
+  }                                        
+  return 0;                                
+}
+
` + +Finally, a coverage mapping counter can also represent an execution count of +of zero. The zero counter is used to provide coverage mapping for +unreachable statements and expressions, like in the example below: + +:raw-html:`
int main() {                  
+  return 0;                   
+  printf("Hello world!\n");    // Unreachable region's counter is zero
+}
+
` + +The zero counters allow the code coverage tool to display proper line execution +counts for the unreachable lines and highlight the unreachable code. +Without them, the tool would think that those lines and regions were still +executed, as it doesn't possess the frontend's knowledge. + +LLVM IR Representation +====================== + +The coverage mapping data is stored in the LLVM IR using a single global +constant structure variable called *__llvm_coverage_mapping* +with the *__llvm_covmap* section specifier. + +For example, let’s consider a C file and how it gets compiled to LLVM: + +.. _coverage mapping sample: + +.. code-block:: c + + int foo() { + return 42; + } + int bar() { + return 13; + } + +The coverage mapping variable generated by Clang is: + +.. code-block:: llvm + + @__llvm_coverage_mapping = internal constant { i32, i32, i32, i32, [2 x { i8*, i32, i32 }], [40 x i8] } + { i32 2, ; The number of function records + i32 20, ; The length of the string that contains the encoded translation unit filenames + i32 20, ; The length of the string that contains the encoded coverage mapping data + i32 0, ; Coverage mapping format version + [2 x { i8*, i32, i32 }] [ ; Function records + { i8*, i32, i32 } { i8* getelementptr inbounds ([3 x i8]* @__llvm_profile_name_foo, i32 0, i32 0), ; Function's name + i32 3, ; Function's name length + i32 9 ; Function's encoded coverage mapping data string length + }, + { i8*, i32, i32 } { i8* getelementptr inbounds ([3 x i8]* @__llvm_profile_name_bar, i32 0, i32 0), ; Function's name + i32 3, ; Function's name length + i32 9 ; Function's encoded coverage mapping data string length + }], + [40 x i8] c"..." ; Encoded data (dissected later) + }, section "__llvm_covmap", align 8 + +Version: +-------- + +The coverage mapping version number can have the following values: + +* 0 — The first (current) version of the coverage mapping format. + +.. _function records: + +Function record: +---------------- + +A function record is a structure of the following type: + +.. code-block:: llvm + + { i8*, i32, i32 } + +It contains the pointer to the function's name, function's name length, +and the length of the encoded mapping data for that function. + +Encoded data: +------------- + +The encoded data is stored in a single string that contains +the encoded filenames used by this translation unit and the encoded coverage +mapping data for each function in this translation unit. + +The encoded data has the following structure: + +``[filenames, coverageMappingDataForFunctionRecord0, coverageMappingDataForFunctionRecord1, ..., padding]`` + +If necessary, the encoded data is padded with zeroes so that the size +of the data string is rounded up to the nearest multiple of 8 bytes. + +Dissecting the sample: +^^^^^^^^^^^^^^^^^^^^^^ + +Here's an overview of the encoded data that was stored in the +IR for the `coverage mapping sample`_ that was shown earlier: + +* The IR contains the following string constant that represents the encoded + coverage mapping data for the sample translation unit: + + .. code-block:: llvm + + c"\01\12/Users/alex/test.c\01\00\00\01\01\01\0C\02\02\01\00\00\01\01\04\0C\02\02\00\00" + +* The string contains values that are encoded in the LEB128 format, which is + used throughout for storing integers.

It could happen due to several reasons: mainly, the usage of +templates and automatic code generators. Though, sometimes user itself could +write the same thing twice :-) + +The main purpose of this pass is to recognize such functions and merge them. + +Why would I want to read this document? +--------------------------------------- +Document is the extension to pass comments and describes the pass logic. It +describes algorithm that is used in order to compare functions, it also +explains how we could combine equal functions correctly, keeping module valid. + +Material is brought in top-down form, so reader could start learn pass from +ideas and end up with low-level algorithm details, thus preparing him for +reading the sources. + +So main goal is do describe algorithm and logic here; the concept. This document +is good for you, if you *don't want* to read the source code, but want to +understand pass algorithms. Author tried not to repeat the source-code and +cover only common cases, and thus avoid cases when after minor code changes we +need to update this document. + + +What should I know to be able to follow along with this document? +----------------------------------------------------------------- + +Reader should be familiar with common compile-engineering principles and LLVM +code fundamentals. In this article we suppose reader is familiar with +`Single Static Assingment `_ +concepts. Understanding of +`IR structure `_ is +also important. + +We will use such terms as +"`module `_", +"`function `_", +"`basic block `_", +"`user `_", +"`value `_", +"`instruction `_". + +As a good start point, Kaleidoscope tutorial could be used: + +:doc:`tutorial/index` + +Especially it's important to understand chapter 3 of tutorial: + +:doc:`tutorial/LangImpl3` + +Reader also should know how passes work in LLVM, he could use next article as a +reference and start point here: + +:doc:`WritingAnLLVMPass` + +What else? Well perhaps reader also should have some experience in LLVM pass +debugging and bug-fixing. + +What I gain by reading this document? +------------------------------------- +Main purpose is to provide reader with comfortable form of algorithms +description, namely the human reading text. Since it could be hard to +understand algorithm straight from the source code: pass uses some principles +that have to be explained first. + +Author wishes to everybody to avoid case, when you read code from top to bottom +again and again, and yet you don't understand why we implemented it that way. + +We hope that after this article reader could easily debug and improve +MergeFunctions pass and thus help LLVM project. + +Narrative structure +------------------- +Article consists of three parts. First part explains pass functionality on the +top-level. Second part describes the comparison procedure itself. The third +part describes the merging process. + +In every part author also tried to put the contents into the top-down form. +First, the top-level methods will be described, while the terminal ones will be +at the end, in the tail of each part. If reader will see the reference to the +method that wasn't described yet, he will find its description a bit below. + +Basics +====== + +How to do it? +------------- +Do we need to merge functions? Obvious thing is: yes that's a quite possible +case, since usually we *do* have duplicates. And it would be good to get rid of +them. But how to detect such a duplicates? The idea is next: we split functions +onto small bricks (parts), then we compare "bricks" amount, and if it equal, +compare "bricks" themselves, and then do our conclusions about functions +themselves. + +What the difference it could be? For example, on machine with 64-bit pointers +(let's assume we have only one address space), one function stores 64-bit +integer, while another one stores a pointer. So if the target is a machine +mentioned above, and if functions are identical, except the parameter type (we +could consider it as a part of function type), then we can treat ``uint64_t`` +and``void*`` as equal. + +It was just an example; possible details are described a bit below. + +As another example reader may imagine two more functions. First function +performs multiplication on 2, while the second one performs arithmetic right +shift on 1. + +Possible solutions +^^^^^^^^^^^^^^^^^^ +Let's briefly consider possible options about how and what we have to implement +in order to create full-featured functions merging, and also what it would +meant for us. + +Equal functions detection, obviously supposes "detector" method to be +implemented, latter should answer the question "whether functions are equal". +This "detector" method consists of tiny "sub-detectors", each of them answers +exactly the same question, but for function parts. + +As the second step, we should merge equal functions. So it should be a "merger" +method. "Merger" accepts two functions *F1* and *F2*, and produces *F1F2* +function, the result of merging. + +Having such a routines in our hands, we can process whole module, and merge all +equal functions. + +In this case, we have to compare every function with every another function. As +reader could notice, this way seems to be quite expensive. Of course we could +introduce hashing and other helpers, but it is still just an optimization, and +thus the level of O(N*N) complexity. + +Can we reach another level? Could we introduce logarithmical search, or random +access lookup? The answer is: "yes". + +Random-access +""""""""""""" +How it could be done? Just convert each function to number, and gather all of +them in special hash-table. Functions with equal hash are equal. Good hashing +means, that every function part must be taken into account. That means we have +to convert every function part into some number, and then add it into hash. +Lookup-up time would be small, but such approach adds some delay due to hashing +routine. + +Logarithmical search +"""""""""""""""""""" +We could introduce total ordering among the functions set, once we had it we +could then implement a logarithmical search. Lookup time still depends on N, +but adds a little of delay (*log(N)*). + +Present state +""""""""""""" +Both of approaches (random-access and logarithmical) has been implemented and +tested. And both of them gave a very good improvement. And what was most +surprising, logarithmical search was faster; sometimes up to 15%. Hashing needs +some extra CPU time, and it is the main reason why it works slower; in most of +cases total "hashing" time was greater than total "logarithmical-search" time. + +So, preference has been granted to the "logarithmical search". + +Though in the case of need, *logarithmical-search* (read "total-ordering") could +be used as a milestone on our way to the *random-access* implementation. + +Every comparison is based either on the numbers or on flags comparison. In +*random-access* approach we could use the same comparison algorithm. During +comparison we exit once we find the difference, but here we might have to scan +whole function body every time (note, it could be slower). Like in +"total-ordering", we will track every numbers and flags, but instead of +comparison, we should get numbers sequence and then create the hash number. So, +once again, *total-ordering* could be considered as a milestone for even faster +(in theory) random-access approach. + +MergeFunctions, main fields and runOnModule +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +There are two most important fields in class: + +``FnTree`` – the set of all unique functions. It keeps items that couldn't be +merged with each other. It is defined as: + +``std::set FnTree;`` + +Here ``FunctionNode`` is a wrapper for ``llvm::Function`` class, with +implemented “<†operator among the functions set (below we explain how it works +exactly; this is a key point in fast functions comparison). + +``Deferred`` – merging process can affect bodies of functions that are in +``FnTree`` already. Obviously such functions should be rechecked again. In this +case we remove them from ``FnTree``, and mark them as to be rescanned, namely +put them into ``Deferred`` list. + +runOnModule +""""""""""" +The algorithm is pretty simple: + +1. Put all module's functions into the *worklist*. + +2. Scan *worklist*'s functions twice: first enumerate only strong functions and +then only weak ones: + + 2.1. Loop body: take function from *worklist* (call it *FCur*) and try to + insert it into *FnTree*: check whether *FCur* is equal to one of functions + in *FnTree*. If there *is* equal function in *FnTree* (call it *FExists*): + merge function *FCur* with *FExists*. Otherwise add function from *worklist* + to *FnTree*. + +3. Once *worklist* scanning and merging operations is complete, check *Deferred* +list. If it is not empty: refill *worklist* contents with *Deferred* list and +do step 2 again, if *Deferred* is empty, then exit from method. + +Comparison and logarithmical search +""""""""""""""""""""""""""""""""""" +Let's recall our task: for every function *F* from module *M*, we have to find +equal functions *F`* in shortest time, and merge them into the single function. + +Defining total ordering among the functions set allows to organize functions +into the binary tree. The lookup procedure complexity would be estimated as +O(log(N)) in this case. But how to define *total-ordering*? + +We have to introduce a single rule applicable to every pair of functions, and +following this rule then evaluate which of them is greater. What kind of rule +it could be? Let's declare it as "compare" method, that returns one of 3 +possible values: + +-1, left is *less* than right, + +0, left and right are *equal*, + +1, left is *greater* than right. + +Of course it means, that we have to maintain +*strict and non-strict order relation properties*: + +* reflexivity (``a <= a``, ``a == a``, ``a >= a``), +* antisymmetry (if ``a <= b`` and ``b <= a`` then ``a == b``), +* transitivity (``a <= b`` and ``b <= c``, then ``a <= c``) +* asymmetry (if ``a < b``, then ``a > b`` or ``a == b``). + +As it was mentioned before, comparison routine consists of +"sub-comparison-routines", each of them also consists +"sub-comparison-routines", and so on, finally it ends up with a primitives +comparison. + +Below, we will use the next operations: + +#. ``cmpNumbers(number1, number2)`` is method that returns -1 if left is less + than right; 0, if left and right are equal; and 1 otherwise. + +#. ``cmpFlags(flag1, flag2)`` is hypothetical method that compares two flags. + The logic is the same as in ``cmpNumbers``, where ``true`` is 1, and + ``false`` is 0. + +The rest of article is based on *MergeFunctions.cpp* source code +(*/lib/Transforms/IPO/MergeFunctions.cpp*). We would like to ask +reader to keep this file open nearby, so we could use it as a reference for +further explanations. + +Now we're ready to proceed to the next chapter and see how it works. + +Functions comparison +==================== +At first, let's define how exactly we compare complex objects. + +Complex objects comparison (function, basic-block, etc) is mostly based on its +sub-objects comparison results. So it is similar to the next "tree" objects +comparison: + +#. For two trees *T1* and *T2* we perform *depth-first-traversal* and have + two sequences as a product: "*T1Items*" and "*T2Items*". + +#. Then compare chains "*T1Items*" and "*T2Items*" in + most-significant-item-first order. Result of items comparison would be the + result of *T1* and *T2* comparison itself. + +FunctionComparator::compare(void) +--------------------------------- +Brief look at the source code tells us, that comparison starts in +“``int FunctionComparator::compare(void)``†method. + +1. First parts to be compared are function's attributes and some properties that +outsides “attributes†term, but still could make function different without +changing its body. This part of comparison is usually done within simple +*cmpNumbers* or *cmpFlags* operations (e.g. +``cmpFlags(F1->hasGC(), F2->hasGC())``). Below is full list of function's +properties to be compared on this stage: + + * *Attributes* (those are returned by ``Function::getAttributes()`` + method). + + * *GC*, for equivalence, *RHS* and *LHS* should be both either without + *GC* or with the same one. + + * *Section*, just like a *GC*: *RHS* and *LHS* should be defined in the + same section. + + * *Variable arguments*. *LHS* and *RHS* should be both either with or + without *var-args*. + + * *Calling convention* should be the same. + +2. Function type. Checked by ``FunctionComparator::cmpType(Type*, Type*)`` +method. It checks return type and parameters type; the method itself will be +described later. + +3. Associate function formal parameters with each other. Then comparing function +bodies, if we see the usage of *LHS*'s *i*-th argument in *LHS*'s body, then, +we want to see usage of *RHS*'s *i*-th argument at the same place in *RHS*'s +body, otherwise functions are different. On this stage we grant the preference +to those we met later in function body (value we met first would be *less*). +This is done by “``FunctionComparator::cmpValues(const Value*, const Value*)``†+method (will be described a bit later). + +4. Function body comparison. As it written in method comments: + +“We do a CFG-ordered walk since the actual ordering of the blocks in the linked +list is immaterial. Our walk starts at the entry block for both functions, then +takes each block from each terminator in order. As an artifact, this also means +that unreachable blocks are ignored.†+ +So, using this walk we get BBs from *left* and *right* in the same order, and +compare them by “``FunctionComparator::compare(const BasicBlock*, const +BasicBlock*)``†method. + +We also associate BBs with each other, like we did it with function formal +arguments (see ``cmpValues`` method below). + +FunctionComparator::cmpType +--------------------------- +Consider how types comparison works. + +1. Coerce pointer to integer. If left type is a pointer, try to coerce it to the +integer type. It could be done if its address space is 0, or if address spaces +are ignored at all. Do the same thing for the right type. + +2. If left and right types are equal, return 0. Otherwise we need to give +preference to one of them. So proceed to the next step. + +3. If types are of different kind (different type IDs). Return result of type +IDs comparison, treating them as a numbers (use ``cmpNumbers`` operation). + +4. If types are vectors or integers, return result of their pointers comparison, +comparing them as numbers. + +5. Check whether type ID belongs to the next group (call it equivalent-group): + + * Void + + * Float + + * Double + + * X86_FP80 + + * FP128 + + * PPC_FP128 + + * Label + + * Metadata. + + If ID belongs to group above, return 0. Since it's enough to see that + types has the same ``TypeID``. No additional information is required. + +6. Left and right are pointers. Return result of address space comparison +(numbers comparison). + +7. Complex types (structures, arrays, etc.). Follow complex objects comparison +technique (see the very first paragraph of this chapter). Both *left* and +*right* are to be expanded and their element types will be checked the same +way. If we get -1 or 1 on some stage, return it. Otherwise return 0. + +8. Steps 1-6 describe all the possible cases, if we passed steps 1-6 and didn't +get any conclusions, then invoke ``llvm_unreachable``, since it's quite +unexpectable case. + +cmpValues(const Value*, const Value*) +------------------------------------- +Method that compares local values. + +This method gives us an answer on a very curious quesion: whether we could treat +local values as equal, and which value is greater otherwise. It's better to +start from example: + +Consider situation when we're looking at the same place in left function "*FL*" +and in right function "*FR*". And every part of *left* place is equal to the +corresponding part of *right* place, and (!) both parts use *Value* instances, +for example: + +.. code-block:: llvm + + instr0 i32 %LV ; left side, function FL + instr0 i32 %RV ; right side, function FR + +So, now our conclusion depends on *Value* instances comparison. + +Main purpose of this method is to determine relation between such values. + +What we expect from equal functions? At the same place, in functions "*FL*" and +"*FR*" we expect to see *equal* values, or values *defined* at the same place +in "*FL*" and "*FR*". + +Consider small example here: + +.. code-block:: llvm + + define void %f(i32 %pf0, i32 %pf1) { + instr0 i32 %pf0 instr1 i32 %pf1 instr2 i32 123 + } + +.. code-block:: llvm + + define void %g(i32 %pg0, i32 %pg1) { + instr0 i32 %pg0 instr1 i32 %pg0 instr2 i32 123 + } + +In this example, *pf0* is associated with *pg0*, *pf1* is associated with *pg1*, +and we also declare that *pf0* < *pf1*, and thus *pg0* < *pf1*. + +Instructions with opcode "*instr0*" would be *equal*, since their types and +opcodes are equal, and values are *associated*. + +Instruction with opcode "*instr1*" from *f* is *greater* than instruction with +opcode "*instr1*" from *g*; here we have equal types and opcodes, but "*pf1* is +greater than "*pg0*". + +And instructions with opcode "*instr2*" are equal, because their opcodes and +types are equal, and the same constant is used as a value. + +What we assiciate in cmpValues? +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +* Function arguments. *i*-th argument from left function associated with + *i*-th argument from right function. +* BasicBlock instances. In basic-block enumeration loop we associate *i*-th + BasicBlock from the left function with *i*-th BasicBlock from the right + function. +* Instructions. +* Instruction operands. Note, we can meet *Value* here we have never seen + before. In this case it is not a function argument, nor *BasicBlock*, nor + *Instruction*. It is global value. It is constant, since its the only + supposed global here. Method also compares: +* Constants that are of the same type. +* If right constant could be losslessly bit-casted to the left one, then we + also compare them. + +How to implement cmpValues? +^^^^^^^^^^^^^^^^^^^^^^^^^^^ +*Association* is a case of equality for us. We just treat such values as equal. +But, in general, we need to implement antisymmetric relation. As it was +mentioned above, to understand what is *less*, we can use order in which we +meet values. If both of values has the same order in function (met at the same +time), then treat values as *associated*. Otherwise – it depends on who was +first. + +Every time we run top-level compare method, we initialize two identical maps +(one for the left side, another one for the right side): + +``map sn_mapL, sn_mapR;`` + +The key of the map is the *Value* itself, the *value* – is its order (call it +*serial number*). + +To add value *V* we need to perform the next procedure: + +``sn_map.insert(std::make_pair(V, sn_map.size()));`` + +For the first *Value*, map will return *0*, for second *Value* map will return +*1*, and so on. + +Then we can check whether left and right values met at the same time with simple +comparison: + +``cmpNumbers(sn_mapL[Left], sn_mapR[Right]);`` + +Of course, we can combine insertion and comparison: + +.. code-block:: c++ + + std::pair + LeftRes = sn_mapL.insert(std::make_pair(Left, sn_mapL.size())), RightRes + = sn_mapR.insert(std::make_pair(Right, sn_mapR.size())); + return cmpNumbers(LeftRes.first->second, RightRes.first->second); + +Let's look, how whole method could be implemented. + +1. we have to start from the bad news. Consider function self and +cross-referencing cases: + +.. code-block:: c++ + + // self-reference unsigned fact0(unsigned n) { return n > 1 ? n + * fact0(n-1) : 1; } unsigned fact1(unsigned n) { return n > 1 ? n * + fact1(n-1) : 1; } + + // cross-reference unsigned ping(unsigned n) { return n!= 0 ? pong(n-1) : 0; + } unsigned pong(unsigned n) { return n!= 0 ? ping(n-1) : 0; } + +.. + + This comparison has been implemented in initial *MergeFunctions* pass + version. But, unfortunately, it is not transitive. And this is the only case + we can't convert to less-equal-greater comparison. It is a seldom case, 4-5 + functions of 10000 (checked on test-suite), and, we hope, reader would + forgive us for such a sacrifice in order to get the O(log(N)) pass time. + +2. If left/right *Value* is a constant, we have to compare them. Return 0 if it +is the same constant, or use ``cmpConstants`` method otherwise. + +3. If left/right is *InlineAsm* instance. Return result of *Value* pointers +comparison. + +4. Explicit association of *L* (left value) and *R* (right value). We need to +find out whether values met at the same time, and thus are *associated*. Or we +need to put the rule: when we treat *L* < *R*. Now it is easy: just return +result of numbers comparison: + +.. code-block:: c++ + + std::pair + LeftRes = sn_mapL.insert(std::make_pair(Left, sn_mapL.size())), + RightRes = sn_mapR.insert(std::make_pair(Right, sn_mapR.size())); + if (LeftRes.first->second == RightRes.first->second) return 0; + if (LeftRes.first->second < RightRes.first->second) return -1; + return 1; + +Now when *cmpValues* returns 0, we can proceed comparison procedure. Otherwise, +if we get (-1 or 1), we need to pass this result to the top level, and finish +comparison procedure. + +cmpConstants +------------ +Performs constants comparison as follows: + +1. Compare constant types using ``cmpType`` method. If result is -1 or 1, goto +step 2, otherwise proceed to step 3. + +2. If types are different, we still can check whether constants could be +losslessly bitcasted to each other. The further explanation is modification of +``canLosslesslyBitCastTo`` method. + + 2.1 Check whether constants are of the first class types + (``isFirstClassType`` check): + + 2.1.1. If both constants are *not* of the first class type: return result + of ``cmpType``. + + 2.1.2. Otherwise, if left type is not of the first class, return -1. If + right type is not of the first class, return 1. + + 2.1.3. If both types are of the first class type, proceed to the next step + (2.1.3.1). + + 2.1.3.1. If types are vectors, compare their bitwidth using the + *cmpNumbers*. If result is not 0, return it. + + 2.1.3.2. Different types, but not a vectors: + + * if both of them are pointers, good for us, we can proceed to step 3. + * if one of types is pointer, return result of *isPointer* flags + comparison (*cmpFlags* operation). + * otherwise we have no methods to prove bitcastability, and thus return + result of types comparison (-1 or 1). + +Steps below are for the case when types are equal, or case when constants are +bitcastable: + +3. One of constants is a "*null*" value. Return the result of +``cmpFlags(L->isNullValue, R->isNullValue)`` comparison. + +4. Compare value IDs, and return result if it is not 0: + +.. code-block:: c++ + + if (int Res = cmpNumbers(L->getValueID(), R->getValueID())) + return Res; + +5. Compare the contents of constants. The comparison depends on kind of +constants, but on this stage it is just a lexicographical comparison. Just see +how it was described in the beginning of "*Functions comparison*" paragraph. +Mathematically it is equal to the next case: we encode left constant and right +constant (with similar way *bitcode-writer* does). Then compare left code +sequence and right code sequence. + +compare(const BasicBlock*, const BasicBlock*) +--------------------------------------------- +Compares two *BasicBlock* instances. + +It enumerates instructions from left *BB* and right *BB*. + +1. It assigns serial numbers to the left and right instructions, using +``cmpValues`` method. + +2. If one of left or right is *GEP* (``GetElementPtr``), then treat *GEP* as +greater than other instructions, if both instructions are *GEPs* use ``cmpGEP`` +method for comparison. If result is -1 or 1, pass it to the top-level +comparison (return it). + + 3.1. Compare operations. Call ``cmpOperation`` method. If result is -1 or + 1, return it. + + 3.2. Compare number of operands, if result is -1 or 1, return it. + + 3.3. Compare operands themselves, use ``cmpValues`` method. Return result + if it is -1 or 1. + + 3.4. Compare type of operands, using ``cmpType`` method. Return result if + it is -1 or 1. + + 3.5. Proceed to the next instruction. + +4. We can finish instruction enumeration in 3 cases: + + 4.1. We reached the end of both left and right basic-blocks. We didn't + exit on steps 1-3, so contents is equal, return 0. + + 4.2. We have reached the end of the left basic-block. Return -1. + + 4.3. Return 1 (the end of the right basic block). + +cmpGEP +------ +Compares two GEPs (``getelementptr`` instructions). + +It differs from regular operations comparison with the only thing: possibility +to use ``accumulateConstantOffset`` method. + +So, if we get constant offset for both left and right *GEPs*, then compare it as +numbers, and return comparison result. + +Otherwise treat it like a regular operation (see previous paragraph). + +cmpOperation +------------ +Compares instruction opcodes and some important operation properties. + +1. Compare opcodes, if it differs return the result. + +2. Compare number of operands. If it differs – return the result. + +3. Compare operation types, use *cmpType*. All the same – if types are +different, return result. + +4. Compare *subclassOptionalData*, get it with ``getRawSubclassOptionalData`` +method, and compare it like a numbers. + +5. Compare operand types. + +6. For some particular instructions check equivalence (relation in our case) of +some significant attributes. For example we have to compare alignment for +``load`` instructions. + +O(log(N)) +--------- +Methods described above implement order relationship. And latter, could be used +for nodes comparison in a binary tree. So we can organize functions set into +the binary tree and reduce the cost of lookup procedure from +O(N*N) to O(log(N)). + +Merging process, mergeTwoFunctions +================================== +Once *MergeFunctions* detected that current function (*G*) is equal to one that +were analyzed before (function *F*) it calls ``mergeTwoFunctions(Function*, +Function*)``. + +Operation affects ``FnTree`` contents with next way: *F* will stay in +``FnTree``. *G* being equal to *F* will not be added to ``FnTree``. Calls of +*G* would be replaced with something else. It changes bodies of callers. So, +functions that calls *G* would be put into ``Deferred`` set and removed from +``FnTree``, and analyzed again. + +The approach is next: + +1. Most wished case: when we can use alias and both of *F* and *G* are weak. We +make both of them with aliases to the third strong function *H*. Actually *H* +is *F*. See below how it's made (but it's better to look straight into the +source code). Well, this is a case when we can just replace *G* with *F* +everywhere, we use ``replaceAllUsesWith`` operation here (*RAUW*). + +2. *F* could not be overridden, while *G* could. It would be good to do the +next: after merging the places where overridable function were used, still use +overridable stub. So try to make *G* alias to *F*, or create overridable tail +call wrapper around *F* and replace *G* with that call. + +3. Neither *F* nor *G* could be overridden. We can't use *RAUW*. We can just +change the callers: call *F* instead of *G*. That's what +``replaceDirectCallers`` does. + +Below is detailed body description. + +If “F†may be overridden +------------------------ +As follows from ``mayBeOverridden`` comments: “whether the definition of this +global may be replaced by something non-equivalent at link timeâ€. If so, thats +ok: we can use alias to *F* instead of *G* or change call instructions itself. + +HasGlobalAliases, removeUsers +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +First consider the case when we have global aliases of one function name to +another. Our purpose is make both of them with aliases to the third strong +function. Though if we keep *F* alive and without major changes we can leave it +in ``FnTree``. Try to combine these two goals. + +Do stub replacement of *F* itself with an alias to *F*. + +1. Create stub function *H*, with the same name and attributes like function +*F*. It takes maximum alignment of *F* and *G*. + +2. Replace all uses of function *F* with uses of function *H*. It is the two +steps procedure instead. First of all, we must take into account, all functions +from whom *F* is called would be changed: since we change the call argument +(from *F* to *H*). If so we must to review these caller functions again after +this procedure. We remove callers from ``FnTree``, method with name +``removeUsers(F)`` does that (don't confuse with ``replaceAllUsesWith``): + + 2.1. ``Inside removeUsers(Value* + V)`` we go through the all values that use value *V* (or *F* in our context). + If value is instruction, we go to function that holds this instruction and + mark it as to-be-analyzed-again (put to ``Deferred`` set), we also remove + caller from ``FnTree``. + + 2.2. Now we can do the replacement: call ``F->replaceAllUsesWith(H)``. + +3. *H* (that now "officially" plays *F*'s role) is replaced with alias to *F*. +Do the same with *G*: replace it with alias to *F*. So finally everywhere *F* +was used, we use *H* and it is alias to *F*, and everywhere *G* was used we +also have alias to *F*. + +4. Set *F* linkage to private. Make it strong :-) + +No global aliases, replaceDirectCallers +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +If global aliases are not supported. We call ``replaceDirectCallers`` then. Just +go through all calls of *G* and replace it with calls of *F*. If you look into +method you will see that it scans all uses of *G* too, and if use is callee (if +user is call instruction and *G* is used as what to be called), we replace it +with use of *F*. + +If “F†could not be overridden, fix it! +""""""""""""""""""""""""""""""""""""""" + +We call ``writeThunkOrAlias(Function *F, Function *G)``. Here we try to replace +*G* with alias to *F* first. Next conditions are essential: + +* target should support global aliases, +* the address itself of *G* should be not significant, not named and not + referenced anywhere, +* function should come with external, local or weak linkage. + +Otherwise we write thunk: some wrapper that has *G's* interface and calls *F*, +so *G* could be replaced with this wrapper. + +*writeAlias* + +As follows from *llvm* reference: + +“Aliases act as *second name* for the aliasee valueâ€. So we just want to create +second name for *F* and use it instead of *G*: + +1. create global alias itself (*GA*), + +2. adjust alignment of *F* so it must be maximum of current and *G's* alignment; + +3. replace uses of *G*: + + 3.1. first mark all callers of *G* as to-be-analyzed-again, using + ``removeUsers`` method (see chapter above), + + 3.2. call ``G->replaceAllUsesWith(GA)``. + +4. Get rid of *G*. + +*writeThunk* + +As it written in method comments: + +“Replace G with a simple tail call to bitcast(F). Also replace direct uses of G +with bitcast(F). Deletes G.†+ +In general it does the same as usual when we want to replace callee, except the +first point: + +1. We generate tail call wrapper around *F*, but with interface that allows use +it instead of *G*. + +2. “As-usualâ€: ``removeUsers`` and ``replaceAllUsesWith`` then. + +3. Get rid of *G*. + +That's it. +========== +We have described how to detect equal functions, and how to merge them, and in +first chapter we have described how it works all-together.

Users +that want the previous ``prefix`` semantics should instead use +``prologue``. To motivate this change, let's examine the primary +usecases that these attributes aim to serve, + + 1.

Function hot-patching: Enable the user to insert ``nop`` operations + at the beginning of the function which can later be safely replaced + with a call to some instrumentation facility. + + 3.

GHC is one example of a + compiler that needs this functionality for its + tables-next-to-code functionality. + +Previously ``prefix`` served cases (1) and (2) quite well by allowing the user +to introduce arbitrary data at the entrypoint but before the function +body. Case (3), however, was poorly handled by this approach as it +required that prefix data was valid executable code. + +In this release the concept of prefix data has been redefined to be +data which occurs immediately before the function entrypoint (i.e. the +symbol address). Since prefix data now occurs before the function +entrypoint, there is no need for the data to be valid code. + +The previous notion of prefix data now goes under the name "prologue +data" to emphasize its duality with the function epilogue. + +The intention here is to handle cases (1) and (2) with prologue data and +case (3) with prefix data.

Not all remaining directives will be -implemented, as we made judgement calls on the need versus the complexity, -and have chosen simplicity and future compatibility where hard decisions -had to be made. The major difference is, as stated above, the IAS validates -all inline ASM, not just for object emission, and that cause trouble with -some uses of inline ASM as pre-processor magic. - -So, while the IAS is good enough to compile large projects (including most -of the Linux kernel), there are a few things that we can't (and probably -won't) do. For those cases, please use ``-fno-integrated-as`` in Clang. - -Exception handling is another big change. After extensive testing and -changes to cooperate with Dwarf unwinding, EHABI is enabled by default. -The options ``-arm-enable-ehabi`` and ``-arm-enable-ehabi-descriptors``, -which were used to enable EHABI in the previous releases, are removed now. - -This means all ARM code will emit EH unwind tables, or CFI unwinding (for -debug/profiling), or both. To avoid run-time inconsistencies, C code will -also emit EH tables (in case they interoperate with C++ code), as is the -case for other architectures (ex. x86_64). Changes to the MIPS Target -------------------------- -There has been a large amount of improvements to the MIPS target which can be -broken down into subtarget, ABI, and Integrated Assembler changes. +During this release the MIPS target has reached a few major milestones. The +compiler has gained support for MIPS-II and MIPS-III; become ABI-compatible +with GCC for big and little endian O32, N32, and N64; and is now able to +compile the Linux kernel for 32-bit targets. Additionally, LLD now supports +microMIPS for the O32 ABI on little endian targets. -Subtargets -^^^^^^^^^^ +ABI +^^^ -Added support for Release 6 of the MIPS32 and MIPS64 architecture (MIPS32r6 -and MIPS64r6). Release 6 makes a number of significant changes to the MIPS32 -and MIPS64 architectures. For example, FPU registers are always 64-bits wide, -FPU NaN values conform to IEEE 754 (2008), and the unaligned memory instructions -(such as lwl and lwr) have been replaced with a requirement for ordinary memory -operations to support unaligned operations. Full details of MIPS32 and MIPS64 -Release 6 can be found on the `MIPS64 Architecture page at Imagination -Technologies `_. +A large number of bugs have been fixed for big-endian MIPS targets using the +N32 and N64 ABI's as well as a small number of bugs affecting other ABI's. +Please note that some of these bugs will still affect LLVM-IR generated by +LLVM 3.5 since correct code generation depends on appropriate usage of the +``inreg``, ``signext``, and ``zeroext`` attributes on all function arguments +and returns. -This release also adds experimental support for MIPS-IV, cnMIPS, and Cavium -Octeon CPU's. +There are far too many corrections to provide a complete list but here are a +few notable ones: -Support for the MIPS SIMD Architecture (MSA) has been improved to support MSA -on MIPS64. +* Big-endian N32 and N64 now interlinks successfully with GCC compiled code. + Previously this didn't work for the majority of cases. -Support for IEEE 754 (2008) NaN values has been added. +* The registers used to return a structure containing a single 128-bit floating + point member on the N32/N64 ABI's have been changed from those specified by + the ABI documentation to match those used by GCC. The documentation specifies + that ``$f0`` and ``$f2`` should be used but GCC has used ``$f0`` and ``$f1`` + for many years. -ABI and ABI extensions -^^^^^^^^^^^^^^^^^^^^^^ +* Returning a zero-byte struct no longer causes arguments to be read from the + wrong registers when using the O32 ABI. -There has also been considerable ABI work since the 3.4 release. This release -adds support for the N32 ABI, the O32-FPXX ABI Extension, the O32-FP64 ABI -Extension, and the O32-FP64A ABI Extension. +* The exception personality has been changed for 64-bit MIPS targets to + eliminate warnings about relocations in a read-only section. -The N32 ABI is an existing ABI that has now been implemented in LLVM. It is a -64-bit ABI that is similar to N64 but retains 32-bit pointers. N64 remains the -default 64-bit ABI in LLVM. This differs from GCC where N32 is the default -64-bit ABI. +* Incorrect usage of odd-numbered single-precision floating point registers + has been fixed when the fastcc calling convention is used with 64-bit FPU's + and -mno-odd-spreg. -The O32-FPXX ABI Extension is 100% compatible with the O32-ABI and the O32-FP64 -ABI Extension and may be linked with either but may not be linked with both of -these simultaneously. It extends the O32 ABI to allow the same code to execute -without modification on processors with 32-bit FPU registers as well as 64-bit -FPU registers. The O32-FPXX ABI Extension is enabled by default for the O32 ABI -on mips*-img-linux-gnu and mips*-mti-linux-gnu triples and is selected with --mfpxx. It is expected that future releases of LLVM will enable the FPXX -Extension for O32 on all triples. +LLVMLinux +^^^^^^^^^ -The O32-FP64 ABI Extension is an extension to the O32 ABI to fully exploit FPU's -with 64-bit registers and is enabled with -mfp64. This replaces an undocumented -and unsupported O32 extension which was previously enabled with -mfp64. It is -100% compatible with the O32-FPXX ABI Extension. +It is now possible to compile the Linux kernel. This currently requires a small +number of kernel patches. See the `LLVMLinux project +`_ for details. -The O32-FP64A ABI Extension is a restricted form of the O32-FP64 ABI Extension -which allows interlinking with unmodified binaries that use the base O32 ABI. +* Added -mabicalls and -mno-abicalls. The implementation may not be complete + but works sufficiently well for the Linux kernel. -Integrated Assembler -^^^^^^^^^^^^^^^^^^^^ +* Fixed multiple compatibility issues between LLVM's inline assembly support + and GCC's. -The MIPS Integrated Assembler has undergone a substantial overhaul including a -rewrite of the assembly parser. It's not ready for general use in this release -but adventurous users may wish to enable it using ``-fintegrated-as``. +* Added support for a number of directives used by Linux to the Integrated + Assembler. -In this release, the integrated assembler supports the majority of MIPS-I, -MIPS-II, MIPS-III, MIPS-IV, MIPS-V, MIPS32, MIPS32r2, MIPS32r6, MIPS64, -MIPS64r2, and MIPS64r6 as well as some of the Application Specific Extensions -such as MSA. It also supports several of the MIPS specific assembler directives -such as ``.set``, ``.module``, ``.cpload``, etc. +Miscellaneous +^^^^^^^^^^^^^ -Changes to the AArch64 Target ------------------------------ +* Attempting to disassemble l[wd]c[23], s[wd]c[23], cache, and pref no longer + triggers an assertion. -The AArch64 target in LLVM 3.5 is based on substantially different code to the -one in LLVM 3.4, having been created as the result of merging code released by -Apple for targetting iOS with the previously existing backend. +* Added -muclibc and -mglibc to support toolchains that provide both uClibC and + GLibC. -We hope the result is a general improvement in the project. Particularly notable -changes are: +* __SIZEOF_INT128__ is no longer defined for 64-bit targets since 128-bit + integers do not work at this time for this target. -* We should produce faster code, having combined optimisations and ideas from - both sources in the final backend. -* We have a FastISel for AArch64, which should compile time for debug builds (at - -O0). -* We can now target iOS platforms (using the triple ``arm64-apple-ios7.0``). - -Background -^^^^^^^^^^ - -During the 3.5 release cycle, Apple released the source used to generate 64-bit -ARM programs on iOS platforms. This took the form of a separate backend that had -been developed in parallel to, and largely isolation from, the existing -code. - -We decided that maintaining the two backends indefinitely was not an option, -since their features almost entirely overlapped. However, the implementation -details in both were different enough that any merge had to firmly start with -one backend as the core and cherry-pick the best features and optimisations from -the other. - -After discussion, we decided to start with the Apple backend (called ARM64 at -the time) since it was older, more thoroughly tested in production use, and had -fewer idiosyncracies in the implementation details. - -Many people from across the community worked throughout April and May to ensure -that this merge destination had all the features we wanted, from both -sources. In many cases we could simply copy code across; others needed heavy -modification for the new host; in the most worthwhile, we looked at both -implementations and combined the best features of each in an entirely new way. - -We had also decided that the name of the combined backend should be AArch64, -following ARM's official documentation. So, at the end of May the old -AArch64 directory was removed, and ARM64 renamed into its place. +* Using $t4-$t7 with the N32 and N64 ABI is deprecated when ``-fintegrated-as`` + is in use and will be removed in LLVM 3.7. These names have never been + supported by the GNU Assembler for these ABI's. Changes to the PowerPC Target ----------------------------- -The PowerPC 64-bit Little Endian subtarget (powerpc64le-unknown-linux-gnu) is -now fully supported. This includes support for the Altivec instruction set. +There are numerous improvements to the PowerPC target in this release: -The Power Architecture 64-Bit ELFv2 ABI Specification is now supported, and -is the default ABI for Little Endian. The ELFv1 ABI remains the default ABI -for Big Endian. Currently, it is not possible to override these defaults. -That capability will be available (albeit not recommended) in a future release. +* LLVM now generates the Vector-Scalar eXtension (VSX) instructions from + version 2.06 of the Power ISA, for both big- and little-endian targets. -Links to the ELFv2 ABI specification and to the Power ISA Version 2.07 -specification may be found `here `_ (free registration required). -Efforts are underway to move this to a location that doesn't require -registration, but the planned site isn't ready yet. +* LLVM now has a POWER8 instruction scheduling description. -Experimental support for the VSX instruction set introduced with ISA 2.06 -is now available using the ``-mvsx`` switch. Work remains on this, so it -is not recommended for production use. VSX is disabled for Little Endian -regardless of this switch setting. +* Address Sanitizer (ASAN) support is now fully functional. -Load/store cost estimates have been improved. +* Performance of simple atomic accesses has been greatly improved. -Constant hoisting has been enabled. +* Atomic fences now use light-weight syncs where possible, again providing + significant performance benefit. -Global named register support has been enabled. +* The PowerPC target now supports PIC levels (-fPIC vs. -fpic). -Initial support for PIC code has been added for the 32-bit ELF subtarget. -Further support will be available in a future release. +* PPC32 SVR4 now supports small-model PIC. +* There have been many smaller bug fixes and performance improvements. -Changes to CMake build system +Changes to the OCaml bindings ----------------------------- -* Building and installing LLVM, Clang and lld sphinx documentation can now be - done in CMake builds. If ``LLVM_ENABLE_SPHINX`` is enabled the - "``docs--html``" and "``docs--man``" targets (e.g. - ``docs-llvm-html``) become available which can be invoked directly (e.g. - ``make docs-llvm-html``) to build only the relevant sphinx documentation. If - ``LLVM_BUILD_DOCS`` is enabled then the sphinx documentation will also be - built as part of the normal build. Enabling this variable also means that if - the ``install`` target is invoked then the built documentation will be - installed. See :ref:`LLVM-specific variables`. +* The bindings now require OCaml >=4.00.0, ocamlfind, + ctypes >=0.3.0 <0.4 and OUnit 2 if tests are enabled. -* Both the Autoconf/Makefile and CMake build systems now generate - ``LLVMConfig.cmake`` (and other files) to export installed libraries. This - means that projects using CMake to build against LLVM libraries can now build - against an installed LLVM built by the Autoconf/Makefile system. See - :ref:`Embedding LLVM in your project` for details. +* The bindings can now be built using cmake as well as autoconf. -* Use of ``llvm_map_components_to_libraries()`` by external projects is - deprecated and the new ``llvm_map_components_to_libnames()`` should be used - instead. +* LLVM 3.5 has, unfortunately, shipped a broken Llvm_executionengine + implementation. In LLVM 3.6, the bindings now fully support MCJIT, + however the interface is reworked from scratch using ctypes + and is not backwards compatible. -External Open Source Projects Using LLVM 3.5 +* Llvm_linker.Mode was removed following the changes in LLVM. + This breaks the interface of Llvm_linker. + +* All combinations of ocamlc/ocamlc -custom/ocamlopt and shared/static + builds of LLVM are now supported. + +* Absolute paths are not embedded into the OCaml libraries anymore. + Either OCaml >=4.02.2 must be used, which includes an rpath-like $ORIGIN + mechanism, or META file must be updated for out-of-tree installations; + see r221139. + +* As usual, many more functions have been exposed to OCaml. + +External Open Source Projects Using LLVM 3.6 ============================================ An exciting aspect of LLVM is that it is used as an enabling technology for a lot of other language and tools projects. This section lists some of the -projects that have already been updated to work with LLVM 3.5. +projects that have already been updated to work with LLVM 3.6. -LDC - the LLVM-based D compiler -------------------------------- - -`D `_ is a language with C-like syntax and static typing. It -pragmatically combines efficiency, control, and modeling power, with safety and -programmer productivity. D supports powerful concepts like Compile-Time Function -Execution (CTFE) and Template Meta-Programming, provides an innovative approach -to concurrency and offers many classical paradigms. - -`LDC `_ uses the frontend from the reference compiler -combined with LLVM as backend to produce efficient native code. LDC targets -x86/x86_64 systems like Linux, OS X, FreeBSD and Windows and also Linux/PPC64. -Ports to other architectures like ARM, AArch64 and MIPS64 are underway. - -Portable Computing Language (pocl) ----------------------------------- - -In addition to producing an easily portable open source OpenCL -implementation, another major goal of `pocl `_ -is improving performance portability of OpenCL programs with -compiler optimizations, reducing the need for target-dependent manual -optimizations. An important part of pocl is a set of LLVM passes used to -statically parallelize multiple work-items with the kernel compiler, even in -the presence of work-group barriers. This enables static parallelization of -the fine-grained static concurrency in the work groups in multiple ways. - -TTA-based Co-design Environment (TCE) -------------------------------------- - -`TCE `_ is a toolset for designing new -exposed datapath processors based on the Transport triggered architecture (TTA). -The toolset provides a complete co-design flow from C/C++ -programs down to synthesizable VHDL/Verilog and parallel program binaries. -Processor customization points include the register files, function units, -supported operations, and the interconnection network. - -TCE uses Clang and LLVM for C/C++/OpenCL C language support, target independent -optimizations and also for parts of code generation. It generates -new LLVM-based code generators "on the fly" for the designed processors and -loads them in to the compiler backend as runtime libraries to avoid -per-target recompilation of larger parts of the compiler chain. - -ISPC ----- - -`ISPC `_ is a C-based language based on the SPMD -(single program, multiple data) programming model that generates efficient -SIMD code for modern processors without the need for complex analysis and -autovectorization. The language exploits the concept of “varying†data types, -which ensure vector-friendly data layout, explicit vectorization and compact -representation of the program. The project uses the LLVM infrastructure for -optimization and code generation. - -Likely ------- - -`Likely `_ is an embeddable just-in-time Lisp for -image recognition and heterogenous architectures. Algorithms are just-in-time -compiled using LLVM’s MCJIT infrastructure to execute on single or -multi-threaded CPUs and potentially OpenCL SPIR or CUDA enabled GPUs. Likely -exploits the observation that while image processing and statistical learning -kernels must be written generically to handle any matrix datatype, at runtime -they tend to be executed repeatedly on the same type. Likely also seeks to -explore new optimizations for statistical learning algorithms by moving them -from an offline model generation step to a compile-time simplification of a -function (the learning algorithm) with constant arguments (the training set). +* A project Additional Information diff --git a/docs/SourceLevelDebugging.rst b/docs/SourceLevelDebugging.rst index 869d3a383107..3a5fa6ef24be 100644 --- a/docs/SourceLevelDebugging.rst +++ b/docs/SourceLevelDebugging.rst @@ -186,11 +186,15 @@ the simple data types ``i32``, ``i1``, ``float``, ``double``, ``mdstring`` and ... } -The first field of a descriptor is always an -``i32`` containing a tag value identifying the content of the descriptor. -The remaining fields are specific to the descriptor.

Use +with caution. Because the intrinsics have experimental status, +compatibility across LLVM releases is not guaranteed. + +LLVM currently supports an alternate mechanism for conservative +garbage collection support using the gc_root intrinsic. The mechanism +described here shares little in common with the alternate +implementation and it is hoped that this mechanism will eventually +replace the gc_root mechanism. + +Overview +======== + +To collect dead objects, garbage collectors must be able to identify +any references to objects contained within executing code, and, +depending on the collector, potentially update them. The collector +does not need this information at all points in code - that would make +the problem much harder - but only at well-defined points in the +execution known as 'safepoints' For most collectors, it is sufficient +to track at least one copy of each unique pointer value. However, for +a collector which wishes to relocate objects directly reachable from +running code, a higher standard is required. + +One additional challenge is that the compiler may compute intermediate +results ("derived pointers") which point outside of the allocation or +even into the middle of another allocation. The eventual use of this +intermediate value must yield an address within the bounds of the +allocation, but such "exterior derived pointers" may be visible to the +collector. Given this, a garbage collector can not safely rely on the +runtime value of an address to indicate the object it is associated +with. If the garbage collector wishes to move any object, the +compiler must provide a mapping, for each pointer, to an indication of +its allocation. + +To simplify the interaction between a collector and the compiled code, +most garbage collectors are organized in terms of three abstractions: +load barriers, store barriers, and safepoints. + +#. A load barrier is a bit of code executed immediately after the + machine load instruction, but before any use of the value loaded. + Depending on the collector, such a barrier may be needed for all + loads, merely loads of a particular type (in the original source + language), or none at all. + +#. Analogously, a store barrier is a code fragement that runs + immediately before the machine store instruction, but after the + computation of the value stored. The most common use of a store + barrier is to update a 'card table' in a generational garbage + collector. + +#. A safepoint is a location at which pointers visible to the compiled + code (i.e. currently in registers or on the stack) are allowed to + change. After the safepoint completes, the actual pointer value + may differ, but the 'object' (as seen by the source language) + pointed to will not. + + Note that the term 'safepoint' is somewhat overloaded. It refers to + both the location at which the machine state is parsable and the + coordination protocol involved in bring application threads to a + point at which the collector can safely use that information. The + term "statepoint" as used in this document refers exclusively to the + former. + +This document focuses on the last item - compiler support for +safepoints in generated code. We will assume that an outside +mechanism has decided where to place safepoints. From our +perspective, all safepoints will be function calls. To support +relocation of objects directly reachable from values in compiled code, +the collector must be able to: + +#. identify every copy of a pointer (including copies introduced by + the compiler itself) at the safepoint, +#. identify which object each pointer relates to, and +#. potentially update each of those copies. + +This document describes the mechanism by which an LLVM based compiler +can provide this information to a language runtime/collector, and +ensure that all pointers can be read and updated if desired. The +heart of the approach is to construct (or rewrite) the IR in a manner +where the possible updates performed by the garbage collector are +explicitly visible in the IR. Doing so requires that we: + +#. create a new SSA value for each potentially relocated pointer, and + ensure that no uses of the original (non relocated) value is + reachable after the safepoint, +#. specify the relocation in a way which is opaque to the compiler to + ensure that the optimizer can not introduce new uses of an + unrelocated value after a statepoint. This prevents the optimizer + from performing unsound optimizations. +#. recording a mapping of live pointers (and the allocation they're + associated with) for each statepoint. + +At the most abstract level, inserting a safepoint can be thought of as +replacing a call instruction with a call to a multiple return value +function which both calls the original target of the call, returns +it's result, and returns updated values for any live pointers to +garbage collected objects. + + Note that the task of identifying all live pointers to garbage + collected values, transforming the IR to expose a pointer giving the + base object for every such live pointer, and inserting all the + intrinsics correctly is explicitly out of scope for this document. + The recommended approach is described in the section of Late + Safepoint Placement below. + +This abstract function call is concretely represented by a sequence of +intrinsic calls known as a 'statepoint sequence'. + + +Let's consider a simple call in LLVM IR: + todo + +Depending on our language we may need to allow a safepoint during the +execution of the function called from this site. If so, we need to +let the collector update local values in the current frame. + +Let's say we need to relocate SSA values 'a', 'b', and 'c' at this +safepoint. To represent this, we would generate the statepoint +sequence: + + todo + +Ideally, this sequence would have been represented as a M argument, N +return value function (where M is the number of values being +relocated + the original call arguments and N is the original return +value + each relocated value), but LLVM does not easily support such a +representation. + +Instead, the statepoint intrinsic marks the actual site of the +safepoint or statepoint. The statepoint returns a token value (which +exists only at compile time). To get back the original return value +of the call, we use the 'gc.result' intrinsic. To get the relocation +of each pointer in turn, we use the 'gc.relocate' intrinsic with the +appropriate index. Note that both the gc.relocate and gc.result are +tied to the statepoint. The combination forms a "statepoint sequence" +and represents the entitety of a parseable call or 'statepoint'. + +When lowered, this example would generate the following x86 assembly:: + put assembly here + +Each of the potentially relocated values has been spilled to the +stack, and a record of that location has been recorded to the +:ref:`Stack Map section `.

Assuming that control flow follows the safepoint, +there is no way to observe externally whether the null comparison is +performed before or after the safepoint. (Remember, the original +Value is unmodified by the safepoint.) The compiler is free to make +either scheduling choice. + +The actual correctness property implemented is slightly stronger than +this. We require that there be no *static path* on which a +potentially relocated pointer is 'observably-after' it may have been +relocated. This is slightly stronger than is strictly necessary (and +thus may disallow some otherwise valid programs), but greatly +simplifies reasoning about correctness of the compiled code. + +By construction, this property will be upheld by the optimizer if +correctly established in the source IR.

In the course of this tutorial, we have -grown our little Kaleidoscope language from being a useless toy, to -being a semi-interesting (but probably still useless) toy. :) +Welcome to Chapter 8 of the "`Implementing a language with +LLVM `_" tutorial. In chapters 1 through 7, we've built a +decent little programming language with functions and variables. +What happens if something goes wrong though, how do you debug your +program? -It is interesting to see how far we've come, and how little code it has -taken. We built the entire lexer, parser, AST, code generator, and an -interactive run-loop (with a JIT!) by-hand in under 700 lines of -(non-comment/non-blank) code. +Source level debugging uses formatted data that helps a debugger +translate from binary and the state of the machine back to the +source that the programmer wrote. In LLVM we generally use a format +called `DWARF `_. DWARF is a compact encoding +that represents types, source locations, and variable locations. -Our little language supports a couple of interesting features: it -supports user defined binary and unary operators, it uses JIT -compilation for immediate evaluation, and it supports a few control flow -constructs with SSA construction. +The short summary of this chapter is that we'll go through the +various things you have to add to a programming language to +support debug info, and how you translate that into DWARF. -Part of the idea of this tutorial was to show you how easy and fun it -can be to define, build, and play with languages. Building a compiler -need not be a scary or mystical process! Now that you've seen some of -the basics, I strongly encourage you to take the code and hack on it. -For example, try adding: +Caveat: For now we can't debug via the JIT, so we'll need to compile +our program down to something small and standalone. As part of this +we'll make a few modifications to the running of the language and +how programs are compiled. This means that we'll have a source file +with a simple program written in Kaleidoscope rather than the +interactive JIT. It does involve a limitation that we can only +have one "top level" command at a time to reduce the number of +changes necessary. -- **global variables** - While global variables have questional value - in modern software engineering, they are often useful when putting - together quick little hacks like the Kaleidoscope compiler itself. - Fortunately, our current setup makes it very easy to add global - variables: just have value lookup check to see if an unresolved - variable is in the global variable symbol table before rejecting it. - To create a new global variable, make an instance of the LLVM - ``GlobalVariable`` class. -- **typed variables** - Kaleidoscope currently only supports variables - of type double. This gives the language a very nice elegance, because - only supporting one type means that you never have to specify types. - Different languages have different ways of handling this. The easiest - way is to require the user to specify types for every variable - definition, and record the type of the variable in the symbol table - along with its Value\*. -- **arrays, structs, vectors, etc** - Once you add types, you can start - extending the type system in all sorts of interesting ways. Simple - arrays are very easy and are quite useful for many different - applications. Adding them is mostly an exercise in learning how the - LLVM `getelementptr <../LangRef.html#i_getelementptr>`_ instruction - works: it is so nifty/unconventional, it `has its own - FAQ <../GetElementPtr.html>`_! If you add support for recursive types - (e.g. linked lists), make sure to read the `section in the LLVM - Programmer's Manual <../ProgrammersManual.html#TypeResolve>`_ that - describes how to construct them. -- **standard runtime** - Our current language allows the user to access - arbitrary external functions, and we use it for things like "printd" - and "putchard". As you extend the language to add higher-level - constructs, often these constructs make the most sense if they are - lowered to calls into a language-supplied runtime. For example, if - you add hash tables to the language, it would probably make sense to - add the routines to a runtime, instead of inlining them all the way. -- **memory management** - Currently we can only access the stack in - Kaleidoscope. It would also be useful to be able to allocate heap - memory, either with calls to the standard libc malloc/free interface - or with a garbage collector. If you would like to use garbage - collection, note that LLVM fully supports `Accurate Garbage - Collection <../GarbageCollection.html>`_ including algorithms that - move objects and need to scan/update the stack. -- **debugger support** - LLVM supports generation of `DWARF Debug - info <../SourceLevelDebugging.html>`_ which is understood by common - debuggers like GDB. Adding support for debug info is fairly - straightforward. The best way to understand it is to compile some - C/C++ code with "``clang -g -O0``" and taking a look at what it - produces. -- **exception handling support** - LLVM supports generation of `zero - cost exceptions <../ExceptionHandling.html>`_ which interoperate with - code compiled in other languages. You could also generate code by - implicitly making every function return an error value and checking - it. You could also make explicit use of setjmp/longjmp. There are - many different ways to go here. -- **object orientation, generics, database access, complex numbers, - geometric programming, ...** - Really, there is no end of crazy - features that you can add to the language. -- **unusual domains** - We've been talking about applying LLVM to a - domain that many people are interested in: building a compiler for a - specific language. However, there are many other domains that can use - compiler technology that are not typically considered. For example, - LLVM has been used to implement OpenGL graphics acceleration, - translate C++ code to ActionScript, and many other cute and clever - things. Maybe you will be the first to JIT compile a regular - expression interpreter into native code with LLVM? +Here's the sample program we'll be compiling: -Have fun - try doing something crazy and unusual. Building a language -like everyone else always has, is much less fun than trying something a -little crazy or off the wall and seeing how it turns out.

First, optimization makes keeping source +locations more difficult. In LLVM IR we keep the original source location +for each IR level instruction on the instruction. Optimization passes +should keep the source locations for newly created instructions, but merged +instructions only get to keep a single location - this can cause jumping +around when stepping through optimized programs. Secondly, optimization +can move variables in ways that are either optimized out, shared in memory +with other variables, or difficult to track. For the purposes of this +tutorial we're going to avoid optimization (as you'll see with one of the +next sets of patches). -One nice aspect of LLVM is that it is often capable of preserving target -independence in the IR: you can take the LLVM IR for a -Kaleidoscope-compiled program and run it on any target that LLVM -supports, even emitting C code and compiling that on targets that LLVM -doesn't support natively. You can trivially tell that the Kaleidoscope -compiler generates target-independent code because it never queries for -any target-specific information when generating code. +Ahead-of-Time Compilation Mode +============================== -The fact that LLVM provides a compact, target-independent, -representation for code gets a lot of people excited. Unfortunately, -these people are usually thinking about C or a language from the C -family when they are asking questions about language portability. I say -"unfortunately", because there is really no way to make (fully general) -C code portable, other than shipping the source code around (and of -course, C source code is not actually portable in general either - ever -port a really old application from 32- to 64-bits?). +To highlight only the aspects of adding debug information to a source +language without needing to worry about the complexities of JIT debugging +we're going to make a few changes to Kaleidoscope to support compiling +the IR emitted by the front end into a simple standalone program that +you can execute, debug, and see results. -The problem with C (again, in its full generality) is that it is heavily -laden with target specific assumptions. As one simple example, the -preprocessor often destructively removes target-independence from the -code when it processes the input text: +First we make our anonymous function that contains our top level +statement be our "main": -.. code-block:: c +.. code-block:: udiff - #ifdef __i386__ - int X = 1; - #else - int X = 42; - #endif + - PrototypeAST *Proto = new PrototypeAST("", std::vector()); + + PrototypeAST *Proto = new PrototypeAST("main", std::vector()); -While it is possible to engineer more and more complex solutions to -problems like this, it cannot be solved in full generality in a way that -is better than shipping the actual source code. +just with the simple change of giving it a name. -That said, there are interesting subsets of C that can be made portable. -If you are willing to fix primitive types to a fixed size (say int = -32-bits, and long = 64-bits), don't care about ABI compatibility with -existing binaries, and are willing to give up some other minor features, -you can have portable code. This can make sense for specialized domains -such as an in-kernel language. +Then we're going to remove the command line code wherever it exists: -Safety Guarantees ------------------ +.. code-block:: udiff -Many of the languages above are also "safe" languages: it is impossible -for a program written in Java to corrupt its address space and crash the -process (assuming the JVM has no bugs).

Instead, -I'll make a few observations: +.. code-block:: bash -First, you're right that LLVM does lose information. For example, as of -this writing, there is no way to distinguish in the LLVM IR whether an -SSA-value came from a C "int" or a C "long" on an ILP32 machine (other -than debug info). Both get compiled down to an 'i32' value and the -information about what it came from is lost. The more general issue -here, is that the LLVM type system uses "structural equivalence" instead -of "name equivalence". Another place this surprises people is if you -have two types in a high-level language that have the same structure -(e.g. two different structs that have a single int field): these types -will compile down into a single LLVM type and it will be impossible to -tell what it came from. + Kaleidoscope-Ch8 < fib.ks | & clang -x ir - -Second, while LLVM does lose information, LLVM is not a fixed target: we -continue to enhance and improve it in many different ways. In addition -to adding new features (LLVM did not always support exceptions or debug -info), we also extend the IR to capture important information for -optimization (e.g. whether an argument is sign or zero extended, -information about pointers aliasing, etc). Many of the enhancements are -user-driven: people want LLVM to include some specific feature, so they -go ahead and extend it. +which gives an a.out/a.exe in the current working directory. -Third, it is *possible and easy* to add language-specific optimizations, -and you have a number of choices in how to do it. As one trivial -example, it is easy to add language-specific optimization passes that -"know" things about code compiled for a language. In the case of the C -family, there is an optimization pass that "knows" about the standard C -library functions. If you call "exit(0)" in main(), it knows that it is -safe to optimize that into "return 0;" because C specifies what the -'exit' function does. +Compile Unit +============ -In addition to simple library knowledge, it is possible to embed a -variety of other language-specific information into the LLVM IR. If you -have a specific need and run into a wall, please bring the topic up on -the llvmdev list. At the very worst, you can always treat LLVM as if it -were a "dumb code generator" and implement the high-level optimizations -you desire in your front-end, on the language-specific AST. +The top level container for a section of code in DWARF is a compile unit. +This contains the type and function data for an individual translation unit +(read: one file of source code). So the first thing we need to do is +construct one for our fib.ks file. -Tips and Tricks -=============== +DWARF Emission Setup +==================== -There is a variety of useful tips and tricks that you come to know after -working on/with LLVM that aren't obvious at first glance. Instead of -letting everyone rediscover them, this section talks about some of these -issues. +Similar to the ``IRBuilder`` class we have a +```DIBuilder`` `_ class +that helps in constructing debug metadata for an llvm IR file. It +corresponds 1:1 similarly to ``IRBuilder`` and llvm IR, but with nicer names. +Using it does require that you be more familiar with DWARF terminology than +you needed to be with ``IRBuilder`` and ``Instruction`` names, but if you +read through the general documentation on the +```Metadata Format`` `_ it +should be a little more clear. We'll be using this class to construct all +of our IR level descriptions. Construction for it takes a module so we +need to construct it shortly after we construct our module. We've left it +as a global static variable to make it a bit easier to use. -Implementing portable offsetof/sizeof -------------------------------------- +Next we're going to create a small container to cache some of our frequent +data. The first will be our compile unit, but we'll also write a bit of +code for our one type since we won't have to worry about multiple typed +expressions: -One interesting thing that comes up, if you are trying to keep the code -generated by your compiler "target independent", is that you often need -to know the size of some LLVM type or the offset of some field in an -llvm structure. For example, you might need to pass the size of a type -into a function that allocates memory. +.. code-block:: c++ -Unfortunately, this can vary widely across targets: for example the -width of a pointer is trivially target-specific. However, there is a -`clever way to use the getelementptr -instruction `_ -that allows you to compute this in a portable way. + static DIBuilder *DBuilder; -Garbage Collected Stack Frames ------------------------------- + struct DebugInfo { + DICompileUnit TheCU; + DIType DblTy; -Some languages want to explicitly manage their stack frames, often so -that they are garbage collected or to allow easy implementation of -closures. There are often better ways to implement these features than -explicit stack frames, but `LLVM does support -them, `_ -if you want. It requires your front-end to convert the code into -`Continuation Passing -Style `_ and -the use of tail calls (which LLVM also supports). + DIType getDoubleTy(); + } KSDbgInfo; + + DIType DebugInfo::getDoubleTy() { + if (DblTy.isValid()) + return DblTy; + + DblTy = DBuilder->createBasicType("double", 64, 64, dwarf::DW_ATE_float); + return DblTy; + } + +And then later on in ``main`` when we're constructing our module: + +.. code-block:: c++ + + DBuilder = new DIBuilder(*TheModule); + + KSDbgInfo.TheCU = DBuilder->createCompileUnit( + dwarf::DW_LANG_C, "fib.ks", ".", "Kaleidoscope Compiler", 0, "", 0); + +There are a couple of things to note here. First, while we're producing a +compile unit for a language called Kaleidoscope we used the language +constant for C. This is because a debugger wouldn't necessarily understand +the calling conventions or default ABI for a language it doesn't recognize +and we follow the C ABI in our llvm code generation so it's the closest +thing to accurate. This ensures we can actually call functions from the +debugger and have them execute. Secondly, you'll see the "fib.ks" in the +call to ``createCompileUnit``. This is a default hard coded value since +we're using shell redirection to put our source into the Kaleidoscope +compiler. In a usual front end you'd have an input file name and it would +go there. + +One last thing as part of emitting debug information via DIBuilder is that +we need to "finalize" the debug information. The reasons are part of the +underlying API for DIBuilder, but make sure you do this near the end of +main: + +.. code-block:: c++ + + DBuilder->finalize(); + +before you dump out the module. + +Functions +========= + +Now that we have our ``Compile Unit`` and our source locations, we can add +function definitions to the debug info. So in ``PrototypeAST::Codegen`` we +add a few lines of code to describe a context for our subprogram, in this +case the "File", and the actual definition of the function itself. + +So the context: + +.. code-block:: c++ + + DIFile Unit = DBuilder->createFile(KSDbgInfo.TheCU.getFilename(), + KSDbgInfo.TheCU.getDirectory()); + +giving us a DIFile and asking the ``Compile Unit`` we created above for the +directory and filename where we are currently. Then, for now, we use some +source locations of 0 (since our AST doesn't currently have source location +information) and construct our function definition: + +.. code-block:: c++ + + DIDescriptor FContext(Unit); + unsigned LineNo = 0; + unsigned ScopeLine = 0; + DISubprogram SP = DBuilder->createFunction( + FContext, Name, StringRef(), Unit, LineNo, + CreateFunctionType(Args.size(), Unit), false /* internal linkage */, + true /* definition */, ScopeLine, DIDescriptor::FlagPrototyped, false, F); + +and we now have a DISubprogram that contains a reference to all of our metadata +for the function. + +Source Locations +================ + +The most important thing for debug information is accurate source location - +this makes it possible to map your source code back. We have a problem though, +Kaleidoscope really doesn't have any source location information in the lexer +or parser so we'll need to add it. + +.. code-block:: c++ + + struct SourceLocation { + int Line; + int Col; + }; + static SourceLocation CurLoc; + static SourceLocation LexLoc = {1, 0}; + + static int advance() { + int LastChar = getchar(); + + if (LastChar == '\n' || LastChar == '\r') { + LexLoc.Line++; + LexLoc.Col = 0; + } else + LexLoc.Col++; + return LastChar; + } + +In this set of code we've added some functionality on how to keep track of the +line and column of the "source file". As we lex every token we set our current +current "lexical location" to the assorted line and column for the beginning +of the token. We do this by overriding all of the previous calls to +``getchar()`` with our new ``advance()`` that keeps track of the information +and then we have added to all of our AST classes a source location: + +.. code-block:: c++ + + class ExprAST { + SourceLocation Loc; + + public: + int getLine() const { return Loc.Line; } + int getCol() const { return Loc.Col; } + ExprAST(SourceLocation Loc = CurLoc) : Loc(Loc) {} + virtual std::ostream &dump(std::ostream &out, int ind) { + return out << ':' << getLine() << ':' << getCol() << '\n'; + } + +that we pass down through when we create a new expression: + +.. code-block:: c++ + + LHS = new BinaryExprAST(BinLoc, BinOp, LHS, RHS); + +giving us locations for each of our expressions and variables. + +From this we can make sure to tell ``DIBuilder`` when we're at a new source +location so it can use that when we generate the rest of our code and make +sure that each instruction has source location information. We do this +by constructing another small function: + +.. code-block:: c++ + + void DebugInfo::emitLocation(ExprAST *AST) { + DIScope *Scope; + if (LexicalBlocks.empty()) + Scope = &TheCU; + else + Scope = LexicalBlocks.back(); + Builder.SetCurrentDebugLocation( + DebugLoc::get(AST->getLine(), AST->getCol(), DIScope(*Scope))); + } + +that both tells the main ``IRBuilder`` where we are, but also what scope +we're in. Since we've just created a function above we can either be in +the main file scope (like when we created our function), or now we can be +in the function scope we just created. To represent this we create a stack +of scopes: + +.. code-block:: c++ + + std::vector LexicalBlocks; + std::map FnScopeMap; + +and keep a map of each function to the scope that it represents (a DISubprogram +is also a DIScope). + +Then we make sure to: + +.. code-block:: c++ + + KSDbgInfo.emitLocation(this); + +emit the location every time we start to generate code for a new AST, and +also: + +.. code-block:: c++ + + KSDbgInfo.FnScopeMap[this] = SP; + +store the scope (function) when we create it and use it: + + KSDbgInfo.LexicalBlocks.push_back(&KSDbgInfo.FnScopeMap[Proto]); + +when we start generating the code for each function. + +also, don't forget to pop the scope back off of your scope stack at the +end of the code generation for the function: + +.. code-block:: c++ + + // Pop off the lexical block for the function since we added it + // unconditionally. + KSDbgInfo.LexicalBlocks.pop_back(); + +Variables +========= + +Now that we have functions, we need to be able to print out the variables +we have in scope. Let's get our function arguments set up so we can get +decent backtraces and see how our functions are being called. It isn't +a lot of code, and we generally handle it when we're creating the +argument allocas in ``PrototypeAST::CreateArgumentAllocas``. + +.. code-block:: c++ + + DIScope *Scope = KSDbgInfo.LexicalBlocks.back(); + DIFile Unit = DBuilder->createFile(KSDbgInfo.TheCU.getFilename(), + KSDbgInfo.TheCU.getDirectory()); + DIVariable D = DBuilder->createLocalVariable(dwarf::DW_TAG_arg_variable, + *Scope, Args[Idx], Unit, Line, + KSDbgInfo.getDoubleTy(), Idx); + + Instruction *Call = DBuilder->insertDeclare( + Alloca, D, DBuilder->createExpression(), Builder.GetInsertBlock()); + Call->setDebugLoc(DebugLoc::get(Line, 0, *Scope)); + +Here we're doing a few things. First, we're grabbing our current scope +for the variable so we can say what range of code our variable is valid +through. Second, we're creating the variable, giving it the scope, +the name, source location, type, and since it's an argument, the argument +index. Third, we create an ``lvm.dbg.declare`` call to indicate at the IR +level that we've got a variable in an alloca (and it gives a starting +location for the variable). Lastly, we set a source location for the +beginning of the scope on the declare. + +One interesting thing to note at this point is that various debuggers have +assumptions based on how code and debug information was generated for them +in the past. In this case we need to do a little bit of a hack to avoid +generating line information for the function prologue so that the debugger +knows to skip over those instructions when setting a breakpoint. So in +``FunctionAST::CodeGen`` we add a couple of lines: + +.. code-block:: c++ + + // Unset the location for the prologue emission (leading instructions with no + // location in a function are considered part of the prologue and the debugger + // will run past them when breaking on a function) + KSDbgInfo.emitLocation(nullptr); + +and then emit a new location when we actually start generating code for the +body of the function: + +.. code-block:: c++ + + KSDbgInfo.emitLocation(Body); + +With this we have enough debug information to set breakpoints in functions, +print out argument variables, and call functions. Not too bad for just a +few simple lines of code! + +Full Code Listing +================= + +Here is the complete code listing for our running example, enhanced with +debug information.

In the course of this tutorial, we have +grown our little Kaleidoscope language from being a useless toy, to +being a semi-interesting (but probably still useless) toy. :) + +It is interesting to see how far we've come, and how little code it has +taken. We built the entire lexer, parser, AST, code generator, and an +interactive run-loop (with a JIT!) by-hand in under 700 lines of +(non-comment/non-blank) code. + +Our little language supports a couple of interesting features: it +supports user defined binary and unary operators, it uses JIT +compilation for immediate evaluation, and it supports a few control flow +constructs with SSA construction. + +Part of the idea of this tutorial was to show you how easy and fun it +can be to define, build, and play with languages. Building a compiler +need not be a scary or mystical process! Now that you've seen some of +the basics, I strongly encourage you to take the code and hack on it. +For example, try adding: + +- **global variables** - While global variables have questional value + in modern software engineering, they are often useful when putting + together quick little hacks like the Kaleidoscope compiler itself. + Fortunately, our current setup makes it very easy to add global + variables: just have value lookup check to see if an unresolved + variable is in the global variable symbol table before rejecting it. + To create a new global variable, make an instance of the LLVM + ``GlobalVariable`` class. +- **typed variables** - Kaleidoscope currently only supports variables + of type double. This gives the language a very nice elegance, because + only supporting one type means that you never have to specify types. + Different languages have different ways of handling this. The easiest + way is to require the user to specify types for every variable + definition, and record the type of the variable in the symbol table + along with its Value\*. +- **arrays, structs, vectors, etc** - Once you add types, you can start + extending the type system in all sorts of interesting ways. Simple + arrays are very easy and are quite useful for many different + applications. Adding them is mostly an exercise in learning how the + LLVM `getelementptr <../LangRef.html#i_getelementptr>`_ instruction + works: it is so nifty/unconventional, it `has its own + FAQ <../GetElementPtr.html>`_! If you add support for recursive types + (e.g. linked lists), make sure to read the `section in the LLVM + Programmer's Manual <../ProgrammersManual.html#TypeResolve>`_ that + describes how to construct them. +- **standard runtime** - Our current language allows the user to access + arbitrary external functions, and we use it for things like "printd" + and "putchard". As you extend the language to add higher-level + constructs, often these constructs make the most sense if they are + lowered to calls into a language-supplied runtime. For example, if + you add hash tables to the language, it would probably make sense to + add the routines to a runtime, instead of inlining them all the way. +- **memory management** - Currently we can only access the stack in + Kaleidoscope. It would also be useful to be able to allocate heap + memory, either with calls to the standard libc malloc/free interface + or with a garbage collector. If you would like to use garbage + collection, note that LLVM fully supports `Accurate Garbage + Collection <../GarbageCollection.html>`_ including algorithms that + move objects and need to scan/update the stack. +- **debugger support** - LLVM supports generation of `DWARF Debug + info <../SourceLevelDebugging.html>`_ which is understood by common + debuggers like GDB. Adding support for debug info is fairly + straightforward. The best way to understand it is to compile some + C/C++ code with "``clang -g -O0``" and taking a look at what it + produces. +- **exception handling support** - LLVM supports generation of `zero + cost exceptions <../ExceptionHandling.html>`_ which interoperate with + code compiled in other languages. You could also generate code by + implicitly making every function return an error value and checking + it. You could also make explicit use of setjmp/longjmp. There are + many different ways to go here. +- **object orientation, generics, database access, complex numbers, + geometric programming, ...** - Really, there is no end of crazy + features that you can add to the language. +- **unusual domains** - We've been talking about applying LLVM to a + domain that many people are interested in: building a compiler for a + specific language. However, there are many other domains that can use + compiler technology that are not typically considered. For example, + LLVM has been used to implement OpenGL graphics acceleration, + translate C++ code to ActionScript, and many other cute and clever + things. Maybe you will be the first to JIT compile a regular + expression interpreter into native code with LLVM? + +Have fun - try doing something crazy and unusual. Building a language +like everyone else always has, is much less fun than trying something a +little crazy or off the wall and seeing how it turns out. If you get +stuck or want to talk about it, feel free to email the `llvmdev mailing +list `_: it has lots +of people who are interested in languages and are often willing to help +out. + +Before we end this tutorial, I want to talk about some "tips and tricks" +for generating LLVM IR. These are some of the more subtle things that +may not be obvious, but are very useful if you want to take advantage of +LLVM's capabilities. + +Properties of the LLVM IR +========================= + +We have a couple common questions about code in the LLVM IR form - lets +just get these out of the way right now, shall we? + +Target Independence +------------------- + +Kaleidoscope is an example of a "portable language": any program written +in Kaleidoscope will work the same way on any target that it runs on. +Many other languages have this property, e.g. lisp, java, haskell, +javascript, python, etc (note that while these languages are portable, +not all their libraries are). + +One nice aspect of LLVM is that it is often capable of preserving target +independence in the IR: you can take the LLVM IR for a +Kaleidoscope-compiled program and run it on any target that LLVM +supports, even emitting C code and compiling that on targets that LLVM +doesn't support natively. You can trivially tell that the Kaleidoscope +compiler generates target-independent code because it never queries for +any target-specific information when generating code. + +The fact that LLVM provides a compact, target-independent, +representation for code gets a lot of people excited. Unfortunately, +these people are usually thinking about C or a language from the C +family when they are asking questions about language portability. I say +"unfortunately", because there is really no way to make (fully general) +C code portable, other than shipping the source code around (and of +course, C source code is not actually portable in general either - ever +port a really old application from 32- to 64-bits?). + +The problem with C (again, in its full generality) is that it is heavily +laden with target specific assumptions. As one simple example, the +preprocessor often destructively removes target-independence from the +code when it processes the input text: + +.. code-block:: c + + #ifdef __i386__ + int X = 1; + #else + int X = 42; + #endif + +While it is possible to engineer more and more complex solutions to +problems like this, it cannot be solved in full generality in a way that +is better than shipping the actual source code. + +That said, there are interesting subsets of C that can be made portable. +If you are willing to fix primitive types to a fixed size (say int = +32-bits, and long = 64-bits), don't care about ABI compatibility with +existing binaries, and are willing to give up some other minor features, +you can have portable code. This can make sense for specialized domains +such as an in-kernel language. + +Safety Guarantees +----------------- + +Many of the languages above are also "safe" languages: it is impossible +for a program written in Java to corrupt its address space and crash the +process (assuming the JVM has no bugs). Safety is an interesting +property that requires a combination of language design, runtime +support, and often operating system support. + +It is certainly possible to implement a safe language in LLVM, but LLVM +IR does not itself guarantee safety. The LLVM IR allows unsafe pointer +casts, use after free bugs, buffer over-runs, and a variety of other +problems. Safety needs to be implemented as a layer on top of LLVM and, +conveniently, several groups have investigated this. Ask on the `llvmdev +mailing list `_ if +you are interested in more details. + +Language-Specific Optimizations +------------------------------- + +One thing about LLVM that turns off many people is that it does not +solve all the world's problems in one system (sorry 'world hunger', +someone else will have to solve you some other day). One specific +complaint is that people perceive LLVM as being incapable of performing +high-level language-specific optimization: LLVM "loses too much +information". + +Unfortunately, this is really not the place to give you a full and +unified version of "Chris Lattner's theory of compiler design". Instead, +I'll make a few observations: + +First, you're right that LLVM does lose information. For example, as of +this writing, there is no way to distinguish in the LLVM IR whether an +SSA-value came from a C "int" or a C "long" on an ILP32 machine (other +than debug info). Both get compiled down to an 'i32' value and the +information about what it came from is lost. The more general issue +here, is that the LLVM type system uses "structural equivalence" instead +of "name equivalence". Another place this surprises people is if you +have two types in a high-level language that have the same structure +(e.g. two different structs that have a single int field): these types +will compile down into a single LLVM type and it will be impossible to +tell what it came from. + +Second, while LLVM does lose information, LLVM is not a fixed target: we +continue to enhance and improve it in many different ways. In addition +to adding new features (LLVM did not always support exceptions or debug +info), we also extend the IR to capture important information for +optimization (e.g. whether an argument is sign or zero extended, +information about pointers aliasing, etc). Many of the enhancements are +user-driven: people want LLVM to include some specific feature, so they +go ahead and extend it. + +Third, it is *possible and easy* to add language-specific optimizations, +and you have a number of choices in how to do it. As one trivial +example, it is easy to add language-specific optimization passes that +"know" things about code compiled for a language. In the case of the C +family, there is an optimization pass that "knows" about the standard C +library functions. If you call "exit(0)" in main(), it knows that it is +safe to optimize that into "return 0;" because C specifies what the +'exit' function does. + +In addition to simple library knowledge, it is possible to embed a +variety of other language-specific information into the LLVM IR. If you +have a specific need and run into a wall, please bring the topic up on +the llvmdev list. At the very worst, you can always treat LLVM as if it +were a "dumb code generator" and implement the high-level optimizations +you desire in your front-end, on the language-specific AST. + +Tips and Tricks +=============== + +There is a variety of useful tips and tricks that you come to know after +working on/with LLVM that aren't obvious at first glance. Instead of +letting everyone rediscover them, this section talks about some of these +issues. + +Implementing portable offsetof/sizeof +------------------------------------- + +One interesting thing that comes up, if you are trying to keep the code +generated by your compiler "target independent", is that you often need +to know the size of some LLVM type or the offset of some field in an +llvm structure. For example, you might need to pass the size of a type +into a function that allocates memory. + +Unfortunately, this can vary widely across targets: for example the +width of a pointer is trivially target-specific. However, there is a +`clever way to use the getelementptr +instruction `_ +that allows you to compute this in a portable way. + +Garbage Collected Stack Frames +------------------------------ + +Some languages want to explicitly manage their stack frames, often so +that they are garbage collected or to allow easy implementation of +closures. There are often better ways to implement these features than +explicit stack frames, but `LLVM does support +them, `_ +if you want. It requires your front-end to convert the code into +`Continuation Passing +Style `_ and +the use of tail calls (which LLVM also supports). + diff --git a/examples/BrainF/BrainFDriver.cpp b/examples/BrainF/BrainFDriver.cpp index e2de6bc58d7b..99c8ff36dc61 100644 --- a/examples/BrainF/BrainFDriver.cpp +++ b/examples/BrainF/BrainFDriver.cpp @@ -26,8 +26,8 @@ #include "BrainF.h" #include "llvm/Bitcode/ReaderWriter.h" +#include "llvm/ExecutionEngine/ExecutionEngine.h" #include "llvm/ExecutionEngine/GenericValue.h" -#include "llvm/ExecutionEngine/JIT.h" #include "llvm/IR/Constants.h" #include "llvm/IR/Verifier.h" #include "llvm/Support/CommandLine.h" @@ -107,9 +107,8 @@ int main(int argc, char **argv) { OutputFilename = base+".bc"; } if (OutputFilename != "-") { - std::string ErrInfo; - out = new raw_fd_ostream(OutputFilename.c_str(), ErrInfo, - sys::fs::F_None); + std::error_code EC; + out = new raw_fd_ostream(OutputFilename, EC, sys::fs::F_None); } } @@ -125,13 +124,13 @@ int main(int argc, char **argv) { //Read the BrainF program BrainF bf; - Module *mod = bf.parse(in, 65536, cf, Context); //64 KiB + std::unique_ptr Mod(bf.parse(in, 65536, cf, Context)); // 64 KiB if (in != &std::cin) delete in; - addMainFunction(mod); + addMainFunction(Mod.get()); //Verify generated code - if (verifyModule(*mod)) { + if (verifyModule(*Mod)) { errs() << "Error: module failed verification.

However, the spacing within a single line is fixed. Additional +// spaces will result in an error while reading the file. +// +// Function names must be mangled in order for the profile loader to +// match them in the current translation unit. The two numbers in the +// function header specify how many total samples were accumulated in the +// function (first number), and the total number of samples accumulated +// in the prologue of the function (second number). This head sample +// count provides an indicator of how frequently the function is invoked. +// +// Each sampled line may contain several items. Some are optional (marked +// below): +// +// a. Source line offset. This number represents the line number +// in the function where the sample was collected. The line number is +// always relative to the line where symbol of the function is +// defined. So, if the function has its header at line 280, the offset +// 13 is at line 293 in the file. +// +// Note that this offset should never be a negative number. This could +// happen in cases like macros. The debug machinery will register the +// line number at the point of macro expansion. So, if the macro was +// expanded in a line before the start of the function, the profile +// converter should emit a 0 as the offset (this means that the optimizers +// will not be able to associate a meaningful weight to the instructions +// in the macro). +// +// b. [OPTIONAL] Discriminator. This is used if the sampled program +// was compiled with DWARF discriminator support +// (http://wiki.dwarfstd.org/index.php?title=Path_Discriminators). +// DWARF discriminators are unsigned integer values that allow the +// compiler to distinguish between multiple execution paths on the +// same source line location. +// +// For example, consider the line of code ``if (cond) foo(); else bar();``. +// If the predicate ``cond`` is true 80% of the time, then the edge +// into function ``foo`` should be considered to be taken most of the +// time. But both calls to ``foo`` and ``bar`` are at the same source +// line, so a sample count at that line is not sufficient. The +// compiler needs to know which part of that line is taken more +// frequently. +// +// This is what discriminators provide. In this case, the calls to +// ``foo`` and ``bar`` will be at the same line, but will have +// different discriminator values. This allows the compiler to correctly +// set edge weights into ``foo`` and ``bar``. +// +// c. Number of samples. This is an integer quantity representing the +// number of samples collected by the profiler at this source +// location. +// +// d. [OPTIONAL] Potential call targets and samples. If present, this +// line contains a call instruction. This models both direct and +// number of samples. For example, +// +// 130: 7 foo:3 bar:2 baz:7 +// +// The above means that at relative line offset 130 there is a call +// instruction that calls one of ``foo()``, ``bar()`` and ``baz()``, +// with ``baz()`` being the relatively more frequently called target. +// +//===----------------------------------------------------------------------===// + +#include "llvm/ProfileData/SampleProfReader.h" +#include "llvm/Support/Debug.h" +#include "llvm/Support/ErrorOr.h" +#include "llvm/Support/LEB128.h" +#include "llvm/Support/LineIterator.h" +#include "llvm/Support/MemoryBuffer.h" +#include "llvm/Support/Regex.h" + +using namespace llvm::sampleprof; +using namespace llvm; + +/// \brief Print the samples collected for a function on stream \p OS. +/// +/// \param OS Stream to emit the output to. +void FunctionSamples::print(raw_ostream &OS) { + OS << TotalSamples << ", " << TotalHeadSamples << ", " << BodySamples.size() + << " sampled lines\n"; + for (const auto &SI : BodySamples) { + LineLocation Loc = SI.first; + const SampleRecord &Sample = SI.second; + OS << "\tline offset: " << Loc.LineOffset + << ", discriminator: " << Loc.Discriminator + << ", number of samples: " << Sample.getSamples(); + if (Sample.hasCalls()) { + OS << ", calls:"; + for (const auto &I : Sample.getCallTargets()) + OS << " " << I.first() << ":" << I.second; + } + OS << "\n"; + } + OS << "\n"; +} + +/// \brief Dump the function profile for \p FName. +/// +/// \param FName Name of the function to print. +/// \param OS Stream to emit the output to. +void SampleProfileReader::dumpFunctionProfile(StringRef FName, + raw_ostream &OS) { + OS << "Function: " << FName << ": "; + Profiles[FName].print(OS); +} + +/// \brief Dump all the function profiles found on stream \p OS. +void SampleProfileReader::dump(raw_ostream &OS) { + for (const auto &I : Profiles) + dumpFunctionProfile(I.getKey(), OS); +} + +/// \brief Load samples from a text file. +/// +/// See the documentation at the top of the file for an explanation of +/// the expected format. +/// +/// \returns true if the file was loaded successfully, false otherwise. +std::error_code SampleProfileReaderText::read() { + line_iterator LineIt(*Buffer, /*SkipBlanks=*/true, '#'); + + // Read the profile of each function.
