\fBclang\fP is a C, C++, and Objective\-C compiler which encompasses
preprocessing, parsing, optimization, code generation, assembly, and linking.
Depending on which high\-level mode setting is passed, Clang will stop before
doing a full link. While Clang is highly integrated, it is important to
understand the stages of compilation, to understand how to invoke it. These
stages are:

.B Driver
The clang executable is actually a small driver which controls the overall
execution of other tools such as the compiler, assembler and linker.
Typically you do not need to interact with the driver, but you
transparently use it to run the other tools.
.TP
.B Preprocessing
This stage handles tokenization of the input source file, macro expansion,
#include expansion and handling of other preprocessor directives. The output of
this stage is typically called a ".i" (for C), ".ii" (for C++), ".mi" (for
Objective-C) , or ".mii" (for Objective-C++) file.
.It Sy Parsing and Semantic Analysis
This stage parses the input file, translating preprocessor tokens into a parse
tree. Once in the form of a parser tree, it applies semantic analysis to compute
types for expressions as well and determine whether the code is well formed. This
stage is responsible for generating most of the compiler warnings as well as
parse errors. The output of this stage is an "Abstract Syntax Tree" (AST).
.It Sy Code Generation and Optimization
This stage translates an AST into low-level intermediate code (known as "LLVM
IR") and ultimately to machine code. This phase is responsible for optimizing
the generated code and handling target-specific code generation. The output of
this stage is typically called a ".s" file or "assembly" file.

The output of this stage is typically called a ".s" file or "assembly" file.
.sp
Clang also supports the use of an integrated assembler, in which the code
generator produces object files directly. This avoids the overhead of generating
the ".s" file and of calling the target assembler.
.It Sy Assembler
This stage runs the target assembler to translate the output of the compiler
into a target object file. The output of this stage is typically called a ".o"
file or "object" file.

This stage runs the target assembler to translate the output of the
compiler into a target object file. The output of this stage is typically
called a ".o" file or "object" file.

This stage runs the target linker to merge multiple object files into an
executable or dynamic library. The output of this stage is typically called an
"a.out", ".dylib" or ".so" file.

The Clang compiler supports a large number of options to control each of these
stages. In addition to compilation of code, Clang also supports other tools:

Clang supports a number of optimizations to reduce the size of debug
information in the binary. They work based on the assumption that the
debug type information can be spread out over multiple compilation
units. For instance, Clang will not emit type definitions for types
that are not needed by a module and could be replaced with a forward
declaration. Further, Clang will only emit type info for a dynamic
C++ class in the module that contains the vtable for the class.
.Pp
The
.Sy -fstandalone-debug

\fBlli\fP directly executes programs in LLVM bitcode format. It takes a program
in LLVM bitcode format and executes it using a just\-in\-time compiler, if one is
available for the current architecture, or an interpreter. \fBlli\fP takes all of
the same code generator options as llc|llc, but they are only effective when
\fBlli\fP is using the just\-in\-time compiler.
in LLVM bitcode format and executes it using a just\-in\-time compiler or an
interpreter.
.sp
\fBlli\fP is \fInot\fP an emulator. It will not execute IR of different architectures
and it can only interpret (or JIT\-compile) for the host architecture.
.sp
The JIT compiler takes the same arguments as other tools, like \fBllc\fP,
but they don\(aqt necessarily work for the interpreter.
.sp
If \fIfilename\fP is not specified, then \fBlli\fP reads the LLVM bitcode for the
program from standard input.

\fBllvm\-profdata merge\fP [\fIoptions\fP] [\fIfilenames...\fP]
\fBllvm\-profdata merge\fP [\fIoptions\fP] [\fIfilename...\fP]
.SS DESCRIPTION
.sp
\fBllvm\-profdata merge\fP takes several profile data files
generated by PGO instrumentation and merges them together into a single
indexed profile data file.
.sp
By default profile data is merged without modification. This means that the
relative importance of each input file is proportional to the number of samples
or counts it contains. In general, the input from a longer training run will be
interpreted as relatively more important than a shorter run. Depending on the
nature of the training runs it may be useful to adjust the weight given to each
input file by using the \fB\-weighted\-input\fP option.
