If a bug is detected, the program will print an error message to stderr and
exit with a non-zero exit code. To make AddressSanitizer symbolize its output
exit with a non-zero exit code. AddressSanitizer exits on the first detected error.
This is by design:
* This approach allows AddressSanitizer to produce faster and smaller generated code
(both by ~5%).
* Fixing bugs becomes unavoidable. AddressSanitizer does not produce
false alarms. Once a memory corruption occurs, the program is in an inconsistent
state, which could lead to confusing results and potentially misleading
subsequent reports.
If your process is sandboxed and you are running on OS X 10.10 or earlier, you
will need to set ``DYLD_INSERT_LIBRARIES`` environment variable and point it to
the ASan library that is packaged with the compiler used to build the
executable. (You can find the library by searching for dynamic libraries with
``asan`` in their name.) If the environment variable is not set, the process will
try to re-exec. Also keep in mind that when moving the executable to another machine,
the ASan library will also need to be copied over.
Symbolizing the Reports
=========================
To make AddressSanitizer symbolize its output
you need to set the ``ASAN_SYMBOLIZER_PATH`` environment variable to point to
the ``llvm-symbolizer`` binary (or make sure ``llvm-symbolizer`` is in your
``$PATH``):

AddressSanitizer exits on the first detected error. This is by design.
One reason: it makes the generated code smaller and faster (both by
~5%). Another reason: this makes fixing bugs unavoidable. With Valgrind,
it is often the case that users treat Valgrind warnings as false
positives (which they are not) and don't fix them.
Additional Checks

Initialization order checking
-----------------------------
AddressSanitizer can optionally detect dynamic initialization order problems,
when initialization of globals defined in one translation unit uses
globals defined in another translation unit. To enable this check at runtime,
you should set environment variable
``ASAN_OPTIONS=check_initialization_order=1``.
Note that this option is not supported on OS X.
Memory leak detection
---------------------
For more information on leak detector in AddressSanitizer, see
:doc:`LeakSanitizer`. The leak detection is turned on by default on Linux;
however, it is not yet supported on other platforms.
Issue Suppression
=================
AddressSanitizer is not expected to produce false positives. If you see one,
look again; most likely it is a true positive!
Suppressing Reports in External Libraries
-----------------------------------------
Runtime interposition allows AddressSanitizer to find bugs in code that is
not being recompiled. If you run into an issue in external libraries, we
recommend immediately reporting it to the library maintainer so that it
gets addressed. However, you can use the following suppression mechanism
to unblock yourself and continue on with the testing. This suppression
mechanism should only be used for suppressing issues in external code; it
does not work on code recompiled with AddressSanitizer. To suppress errors
in external libraries, set the ``ASAN_OPTIONS`` environment variable to point
to a suppression file. You can either specify the full path to the file or the
path of the file relative to the location of your executable.
.. code-block:: bash
ASAN_OPTIONS=suppressions=MyASan.supp
Use the following format to specify the names of the functions or libraries
you want to suppress. You can see these in the error report. Remember that
the narrower the scope of the suppression, the more bugs you will be able to
catch.

clang - the Clang C, C++, and Objective-C compiler
==================================================
SYNOPSIS
--------
:program:`clang` [*options*] *filename ...*
DESCRIPTION
-----------
:program:`clang` 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:
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.
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.
Parsing and Semantic Analysis
This stage parses the input file, translating preprocessor tokens into a
parse tree. Once in the form of a parse 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).
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.
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.
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.
Linker
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.
:program:`Clang Static Analyzer`
The Clang Static Analyzer is a tool that scans source code to try to find bugs
through code analysis. This tool uses many parts of Clang and is built into
the same driver. Please see <http://clang-analyzer.llvm.org> for more details
on how to use the static analyzer.
OPTIONS
-------
Stage Selection Options
~~~~~~~~~~~~~~~~~~~~~~~
.. option:: -E
Run the preprocessor stage.
.. option:: -fsyntax-only
Run the preprocessor, parser and type checking stages.
.. option:: -S
Run the previous stages as well as LLVM generation and optimization stages
and target-specific code generation, producing an assembly file.
.. option:: -c
Run all of the above, plus the assembler, generating a target ".o" object file.
.. option:: no stage selection option
If no stage selection option is specified, all stages above are run, and the
linker is run to combine the results into an executable or shared library.
Language Selection and Mode Options
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. option:: -x <language>
Treat subsequent input files as having type language.
.. option:: -std=<language>
Specify the language standard to compile for.
.. option:: -stdlib=<library>
Specify the C++ standard library to use; supported options are libstdc++ and
libc++.
.. option:: -ansi
Same as -std=c89.
.. option:: -ObjC, -ObjC++
Treat source input files as Objective-C and Object-C++ inputs respectively.
.. option:: -trigraphs
Enable trigraphs.
.. option:: -ffreestanding
Indicate that the file should be compiled for a freestanding, not a hosted,
environment.
.. option:: -fno-builtin
Disable special handling and optimizations of builtin functions like
:c:func:`strlen` and :c:func:`malloc`.
.. option:: -fmath-errno
Indicate that math functions should be treated as updating :c:data:`errno`.
.. option:: -fpascal-strings
Enable support for Pascal-style strings with "\\pfoo".
.. option:: -fms-extensions
Enable support for Microsoft extensions.
.. option:: -fmsc-version=
Set _MSC_VER. Defaults to 1300 on Windows. Not set otherwise.
.. option:: -fborland-extensions
Enable support for Borland extensions.
.. option:: -fwritable-strings
Make all string literals default to writable. This disables uniquing of
strings and other optimizations.
.. option:: -flax-vector-conversions
Allow loose type checking rules for implicit vector conversions.
.. option:: -fblocks
Enable the "Blocks" language feature.
.. option:: -fobjc-gc-only
Indicate that Objective-C code should be compiled in GC-only mode, which only
works when Objective-C Garbage Collection is enabled.
.. option:: -fobjc-gc
Indicate that Objective-C code should be compiled in hybrid-GC mode, which
works with both GC and non-GC mode.
.. option:: -fobjc-abi-version=version
Select the Objective-C ABI version to use. Available versions are 1 (legacy
"fragile" ABI), 2 (non-fragile ABI 1), and 3 (non-fragile ABI 2).
.. option:: -fobjc-nonfragile-abi-version=<version>
Select the Objective-C non-fragile ABI version to use by default. This will
only be used as the Objective-C ABI when the non-fragile ABI is enabled
(either via :option:`-fobjc-nonfragile-abi`, or because it is the platform
default).
.. option:: -fobjc-nonfragile-abi
Enable use of the Objective-C non-fragile ABI. On platforms for which this is
the default ABI, it can be disabled with :option:`-fno-objc-nonfragile-abi`.
Target Selection Options
~~~~~~~~~~~~~~~~~~~~~~~~
Clang fully supports cross compilation as an inherent part of its design.
Depending on how your version of Clang is configured, it may have support for a
number of cross compilers, or may only support a native target.
.. option:: -arch <architecture>
Specify the architecture to build for.
.. option:: -mmacosx-version-min=<version>
When building for Mac OS X, specify the minimum version supported by your
application.
.. option:: -miphoneos-version-min
When building for iPhone OS, specify the minimum version supported by your
application.
.. option:: -march=<cpu>
Specify that Clang should generate code for a specific processor family
member and later. For example, if you specify -march=i486, the compiler is
allowed to generate instructions that are valid on i486 and later processors,
but which may not exist on earlier ones.
Code Generation Options
~~~~~~~~~~~~~~~~~~~~~~~
.. option:: -O0, -O1, -O2, -O3, -Ofast, -Os, -Oz, -O, -O4
Specify which optimization level to use:
:option:`-O0` Means "no optimization": this level compiles the fastest and
generates the most debuggable code.
:option:`-O1` Somewhere between :option:`-O0` and :option:`-O2`.
:option:`-O2` Moderate level of optimization which enables most
optimizations.
:option:`-O3` Like :option:`-O2`, except that it enables optimizations that
take longer to perform or that may generate larger code (in an attempt to
make the program run faster).
:option:`-Ofast` Enables all the optimizations from :option:`-O3` along
with other aggressive optimizations that may violate strict compliance with
language standards.
:option:`-Os` Like :option:`-O2` with extra optimizations to reduce code
size.
:option:`-Oz` Like :option:`-Os` (and thus :option:`-O2`), but reduces code
size further.
:option:`-O` Equivalent to :option:`-O2`.
:option:`-O4` and higher
Currently equivalent to :option:`-O3`
.. option:: -g
Generate debug information. Note that Clang debug information works best at -O0.
.. option:: -fstandalone-debug -fno-standalone-debug
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.
The :option:`-fstandalone-debug` option turns off these optimizations.
This is useful when working with 3rd-party libraries that don't come with
debug information. This is the default on Darwin. Note that Clang will
never emit type information for types that are not referenced at all by the
program.
.. option:: -fexceptions
Enable generation of unwind information. This allows exceptions to be thrown
through Clang compiled stack frames. This is on by default in x86-64.
.. option:: -ftrapv
Generate code to catch integer overflow errors. Signed integer overflow is
undefined in C. With this flag, extra code is generated to detect this and
abort when it happens.
.. option:: -fvisibility
This flag sets the default visibility level.
.. option:: -fcommon
This flag specifies that variables without initializers get common linkage.
It can be disabled with :option:`-fno-common`.
.. option:: -ftls-model=<model>
Set the default thread-local storage (TLS) model to use for thread-local
variables. Valid values are: "global-dynamic", "local-dynamic",
"initial-exec" and "local-exec". The default is "global-dynamic". The default
model can be overridden with the tls_model attribute. The compiler will try
to choose a more efficient model if possible.
.. option:: -flto, -emit-llvm
Generate output files in LLVM formats, suitable for link time optimization.
When used with :option:`-S` this generates LLVM intermediate language
assembly files, otherwise this generates LLVM bitcode format object files
(which may be passed to the linker depending on the stage selection options).
Driver Options
~~~~~~~~~~~~~~
.. option:: -###
Print (but do not run) the commands to run for this compilation.
.. option:: --help
Display available options.
.. option:: -Qunused-arguments
Do not emit any warnings for unused driver arguments.
.. option:: -Wa,<args>
Pass the comma separated arguments in args to the assembler.
.. option:: -Wl,<args>
Pass the comma separated arguments in args to the linker.
.. option:: -Wp,<args>
Pass the comma separated arguments in args to the preprocessor.
.. option:: -Xanalyzer <arg>
Pass arg to the static analyzer.
.. option:: -Xassembler <arg>
Pass arg to the assembler.
.. option:: -Xlinker <arg>
Pass arg to the linker.
.. option:: -Xpreprocessor <arg>
Pass arg to the preprocessor.
.. option:: -o <file>
Write output to file.
.. option:: -print-file-name=<file>
Print the full library path of file.
.. option:: -print-libgcc-file-name
Print the library path for "libgcc.a".
.. option:: -print-prog-name=<name>
Print the full program path of name.
.. option:: -print-search-dirs
Print the paths used for finding libraries and programs.
.. option:: -save-temps
Save intermediate compilation results.
.. option:: -integrated-as, -no-integrated-as
Used to enable and disable, respectively, the use of the integrated
assembler. Whether the integrated assembler is on by default is target
dependent.
.. option:: -time
Time individual commands.
.. option:: -ftime-report
Print timing summary of each stage of compilation.
.. option:: -v
Show commands to run and use verbose output.
Diagnostics Options
~~~~~~~~~~~~~~~~~~~
.. option:: -fshow-column, -fshow-source-location, -fcaret-diagnostics, -fdiagnostics-fixit-info, -fdiagnostics-parseable-fixits, -fdiagnostics-print-source-range-info, -fprint-source-range-info, -fdiagnostics-show-option, -fmessage-length
These options control how Clang prints out information about diagnostics
(errors and warnings). Please see the Clang User's Manual for more information.
Preprocessor Options
~~~~~~~~~~~~~~~~~~~~
.. option:: -D<macroname>=<value>
Adds an implicit #define into the predefines buffer which is read before the
source file is preprocessed.
.. option:: -U<macroname>
Adds an implicit #undef into the predefines buffer which is read before the
source file is preprocessed.
.. option:: -include <filename>
Adds an implicit #include into the predefines buffer which is read before the
source file is preprocessed.
.. option:: -I<directory>
Add the specified directory to the search path for include files.
.. option:: -F<directory>
Add the specified directory to the search path for framework include files.
.. option:: -nostdinc
Do not search the standard system directories or compiler builtin directories
for include files.
.. option:: -nostdlibinc
Do not search the standard system directories for include files, but do
search compiler builtin include directories.
.. option:: -nobuiltininc
Do not search clang's builtin directory for include files.
ENVIRONMENT
-----------
.. envvar:: TMPDIR, TEMP, TMP
These environment variables are checked, in order, for the location to write
temporary files used during the compilation process.
.. envvar:: CPATH
If this environment variable is present, it is treated as a delimited list of
paths to be added to the default system include path list. The delimiter is
the platform dependent delimiter, as used in the PATH environment variable.
Empty components in the environment variable are ignored.
.. envvar:: C_INCLUDE_PATH, OBJC_INCLUDE_PATH, CPLUS_INCLUDE_PATH, OBJCPLUS_INCLUDE_PATH
These environment variables specify additional paths, as for :envvar:`CPATH`, which are
only used when processing the appropriate language.
.. envvar:: MACOSX_DEPLOYMENT_TARGET
If :option:`-mmacosx-version-min` is unspecified, the default deployment
target is read from this environment variable. This option only affects
Darwin targets.
BUGS
----
To report bugs, please visit <http://llvm.org/bugs/>. Most bug reports should
include preprocessed source files (use the :option:`-E` option) and the full
output of the compiler, along with information to reproduce.

stack increases the locality of frequently accessed values on the stack, such
as register spills, return addresses, and small local variables.
Limitations
-----------
SafeStack has not been subjected to a comprehensive security review, and there
exist known weaknesses, including but not limited to the following.
In its current state, the separation of local variables provides protection
against stack buffer overflows, but the safe stack itself is not protected
from being corrupted through a pointer dereference. The Code-Pointer
Integrity paper describes two ways in which we may protect the safe stack:
hardware segmentation on the 32-bit x86 architecture or information hiding
on other architectures.
Even with information hiding, the safe stack would merely be hidden
from attackers by being somewhere in the address space. Depending on the
application, the address could be predictable even on 64-bit address spaces
because not all the bits are addressable, multiple threads each have their
stack, the application could leak the safe stack address to memory via
``__builtin_frame_address``, bugs in the low-level runtime support etc.
Safe stack leaks could be mitigated by writing and deploying a static binary
analysis or a dynamic binary instrumentation based tool to find leaks.
This approach doesn't prevent an attacker from "imbalancing" the safe
stack by say having just one call, and doing two rets (thereby returning
to an address that wasn't meant as a return address). This can be at least
partially mitigated by deploying SafeStack alongside a forward control-flow
integrity mechanism to ensure that calls are made using the correct calling
convention. Clang does not currently implement a comprehensive forward
control-flow integrity protection scheme; there exists one that protects

SafeStack supports linking statically modules that are compiled with and

dynamic libraries with SafeStack is not supported.
Signal handlers that use ``sigaltstack()`` must not use the unsafe stack (see
``__attribute__((no_sanitize("safe-stack")))`` below).
Programs that use APIs from ``ucontext.h`` are not supported yet.
Security
--------
SafeStack protects return addresses, spilled registers and local variables that
are always accessed in a safe way by separating them in a dedicated safe stack
region. The safe stack is automatically protected against stack-based buffer
overflows, since it is disjoint from the unsafe stack in memory, and it itself
is always accessed in a safe way. In the current implementation, the safe stack
is protected against arbitrary memory write vulnerabilities though
randomization and information hiding: the safe stack is allocated at a random
address and the instrumentation ensures that no pointers to the safe stack are
ever stored outside of the safe stack itself (see limitations below).
Known security limitations
~~~~~~~~~~~~~~~~~~~~~~~~~~
A complete protection against control-flow hijack attacks requires combining
SafeStack with another mechanism that enforces the integrity of code pointers
that are stored on the heap or the unsafe stack, such as `CPI
<http://dslab.epfl.ch/proj/cpi/>`_, or a forward-edge control flow integrity
mechanism that enforces correct calling conventions at indirect call sites,
such as `IFCC <http://research.google.com/pubs/archive/42808.pdf>`_ with arity
checks. Clang has control-flow integrity protection scheme for :doc:`C++ virtual
calls <ControlFlowIntegrity>`, but not non-virtual indirect calls. With
SafeStack alone, an attacker can overwrite a function pointer on the heap or
the unsafe stack and cause a program to call arbitrary location, which in turn
might enable stack pivoting and return-oriented programming.
In its current implementation, SafeStack provides precise protection against
stack-based buffer overflows, but protection against arbitrary memory write
vulnerabilities is probabilistic and relies on randomization and information
hiding. The randomization is currently based on system-enforced ASLR and shares
its known security limitations. The safe stack pointer hiding is not perfect
yet either: system library functions such as ``swapcontext``, exception
handling mechanisms, intrinsics such as ``__builtin_frame_address``, or
low-level bugs in runtime support could leak the safe stack pointer. In the
future, such leaks could be detected by static or dynamic analysis tools and
prevented by adjusting such functions to either encrypt the stack pointer when
storing it in the heap (as already done e.g., by ``setjmp``/``longjmp``
implementation in glibc), or store it in a safe region instead.
The `CPI paper <http://dslab.epfl.ch/pubs/cpi.pdf>`_ describes two alternative,
stronger safe stack protection mechanisms, that rely on software fault
isolation, or hardware segmentation (as available on x86-32 and some x86-64
CPUs).
At the moment, SafeStack assumes that the compiler's implementation is correct.
This has not been verified except through manual code inspection, and could
always regress in the future. It's therefore desirable to have a separate
static or dynamic binary verification tool that would check the correctness of
the SafeStack instrumentation in final binaries.

All local variables in functions with this attribute will be stored on the safe

I<input-filenames>
=head1 DESCRIPTION
B<clang> 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:
=over
=item B<Driver>
The B<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.
=item 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.
=item B<Parsing and Semantic Analysis>
This stage parses the input file, translating preprocessor tokens into a parse
tree. Once in the form of a parse 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).
=item B<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.
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.
=item B<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.
=item B<Linker>
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.
=back
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:
B<Clang Static Analyzer>
The Clang Static Analyzer is a tool that scans source code to try to find bugs
through code analysis. This tool uses many parts of Clang and is built into the
same driver. Please see L<http://clang-analyzer.llvm.org> for more details
on how to use the static analyzer.

=head2 Stage Selection Options
=over
=item B<-E>
Run the preprocessor stage.
=item B<-fsyntax-only>

Run all of the above, plus the assembler, generating a target ".o" object file.
=item B<no stage selection option>
If no stage selection option is specified, all stages above are run, and the
linker is run to combine the results into an executable or shared library.

Set _MSC_VER. Defaults to 1300 on Windows. Not set otherwise.
=item B<-fborland-extensions>
Enable support for Borland extensions.
=item B<-fwritable-strings>
Make all string literals default to writable. This disables uniquing of
strings and other optimizations.
=item B<-flax-vector-conversions>
Allow loose type checking rules for implicit vector conversions.
=item B<-fblocks>
Enable the "Blocks" language feature.
=item B<-fobjc-gc-only>
Indicate that Objective-C code should be compiled in GC-only mode, which only
works when Objective-C Garbage Collection is enabled.
=item B<-fobjc-gc>
Indicate that Objective-C code should be compiled in hybrid-GC mode, which works
with both GC and non-GC mode.
=item B<-fobjc-abi-version>=I<version>
Select the Objective-C ABI version to use. Available versions are 1 (legacy
"fragile" ABI), 2 (non-fragile ABI 1), and 3 (non-fragile ABI 2).
=item B<-fobjc-nonfragile-abi-version>=I<version>
Select the Objective-C non-fragile ABI version to use by default. This will only
be used as the Objective-C ABI when the non-fragile ABI is enabled (either via
-fobjc-nonfragile-abi, or because it is the platform default).
=item B<-fobjc-nonfragile-abi>
Enable use of the Objective-C non-fragile ABI. On platforms for which this is
the default ABI, it can be disabled with B<-fno-objc-nonfragile-abi>.
=back
=head2 Target Selection Options
Clang fully supports cross compilation as an inherent part of its design.
Depending on how your version of Clang is configured, it may have support for
a number of cross compilers, or may only support a native target.
=over
=item B<-arch> I<architecture>
Specify the architecture to build for.
=item B<-mmacosx-version-min>=I<version>
When building for Mac OS X, specify the minimum version supported by your
application.
=item B<-miphoneos-version-min>
When building for iPhone OS, specify the minimum version supported by your
application.
=item B<-march>=I<cpu>
Specify that Clang should generate code for a specific processor family member
and later. For example, if you specify -march=i486, the compiler is allowed to
generate instructions that are valid on i486 and later processors, but which
may not exist on earlier ones.
=back
=head2 Code Generation Options
=over
=item B<-O0> B<-O1> B<-O2> B<-O3> B<-Ofast> B<-Os> B<-Oz> B<-O> B<-O4>
Specify which optimization level to use:
=over
=item B<-O0>
Means "no optimization": this level compiles the fastest and
generates the most debuggable code.
=item B<-O1>
Somewhere between B<-O0> and B<-O2>.
=item B<-O2>
Moderate level of optimization which enables most optimizations.
=item B<-O3>
Like B<-O2>, except that it enables optimizations that take longer to perform
or that may generate larger code (in an attempt to make the program run faster).
=item B<-Ofast>
Enables all the optimizations from B<-O3> along with other aggressive
optimizations that may violate strict compliance with language standards.
=item B<-Os>
Like B<-O2> with extra optimizations to reduce code size.
=item B<-Oz>
Like B<-Os> (and thus B<-O2>), but reduces code size further.
=item B<-O>
Equivalent to B<-O2>.
=item B<-O4> and higher
Currently equivalent to B<-O3>
=back
=item B<-g>
Generate debug information. Note that Clang debug information works best at
B<-O0>.
=item B<-fstandalone-debug> B<-fno-standalone-debug>
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.
The B<-fstandalone-debug> option turns off these optimizations. This
is useful when working with 3rd-party libraries that don't come with
debug information. This is the default on Darwin. Note that Clang
will never emit type information for types that are not referenced at
all by the program.
=item B<-fexceptions>
Enable generation of unwind information. This allows exceptions to be thrown
through Clang compiled stack frames. This is on by default in x86-64.
=item B<-ftrapv>
Generate code to catch integer overflow errors. Signed integer overflow is
undefined in C. With this flag, extra code is generated to detect this and abort
when it happens.
=item B<-fvisibility>
This flag sets the default visibility level.
=item B<-fcommon>
This flag specifies that variables without initializers get common linkage. It
can be disabled with B<-fno-common>.
=item B<-ftls-model>
Set the default thread-local storage (TLS) model to use for thread-local
variables. Valid values are: "global-dynamic", "local-dynamic", "initial-exec"
and "local-exec". The default is "global-dynamic". The default model can be
overridden with the tls_model attribute. The compiler will try to choose a more
efficient model if possible.
=item B<-flto> B<-emit-llvm>
Generate output files in LLVM formats, suitable for link time optimization. When
used with B<-S> this generates LLVM intermediate language assembly files,
otherwise this generates LLVM bitcode format object files (which may be passed
to the linker depending on the stage selection options).
=cut
##=item B<-fnext-runtime> B<-fobjc-nonfragile-abi> B<-fgnu-runtime>
##These options specify which Objective-C runtime the code generator should
##target. FIXME: we don't want people poking these generally.

=over
=item B<TMPDIR>, B<TEMP>, B<TMP>
These environment variables are checked, in order, for the location to
write temporary files used during the compilation process.
=item B<CPATH>
If this environment variable is present, it is treated as a delimited
list of paths to be added to the default system include path list. The
delimiter is the platform dependent delimiter, as used in the I<PATH>
environment variable.
Empty components in the environment variable are ignored.
=item B<C_INCLUDE_PATH>, B<OBJC_INCLUDE_PATH>, B<CPLUS_INCLUDE_PATH>,
B<OBJCPLUS_INCLUDE_PATH>
These environment variables specify additional paths, as for CPATH,
which are only used when processing the appropriate language.
=item B<MACOSX_DEPLOYMENT_TARGET>
If -mmacosx-version-min is unspecified, the default deployment target
is read from this environment variable. This option only affects Darwin
targets.

=head1 BUGS
To report bugs, please visit L<http://llvm.org/bugs/>. Most bug reports should
include preprocessed source files (use the B<-E> option) and the full output of
the compiler, along with information to reproduce.

Whether a particular pointer may be "null" is an important concern when working with pointers in the C family of languages. The various nullability attributes indicate whether a particular pointer can be null or not, which makes APIs more expressive and can help static analysis tools identify bugs involving null pointers. Clang supports several kinds of nullability attributes: the ``nonnull`` and ``returns_nonnull`` attributes indicate which function or method parameters and result types can never be null, while nullability type qualifiers indicate which pointer types can be null (``_Nullable``) or cannot be null (``_Nonnull``).
The nullability (type) qualifiers express whether a value of a given pointer type can be null (the ``_Nullable`` qualifier), doesn't have a defined meaning for null (the ``_Nonnull`` qualifier), or for which the purpose of null is unclear (the ``_Null_unspecified`` qualifier). Because nullability qualifiers are expressed within the type system, they are more general than the ``nonnull`` and ``returns_nonnull`` attributes, allowing one to express (for example) a nullable pointer to an array of nonnull pointers. Nullability qualifiers are written to the right of the pointer to which they apply. For example:
.. code-block:: c
// No meaningful result when 'ptr' is null (here, it happens to be undefined behavior).
int fetch(int * _Nonnull ptr) { return *ptr; }
// 'ptr' may be null.
int fetch_or_zero(int * _Nullable ptr) {
return ptr ? *ptr : 0;
}
// A nullable pointer to non-null pointers to const characters.
const char *join_strings(const char * _Nonnull * _Nullable strings, unsigned n);
In Objective-C, there is an alternate spelling for the nullability qualifiers that can be used in Objective-C methods and properties using context-sensitive, non-underscored keywords. For example:
.. code-block:: objective-c
@interface NSView : NSResponder
- (nullable NSView *)ancestorSharedWithView:(nonnull NSView *)aView;
@property (assign, nullable) NSView *superview;
@property (readonly, nonnull) NSArray *subviews;
@end
}];
}
def TypeNonNullDocs : Documentation {
let Category = NullabilityDocs;
let Heading = "_Nonnull";
let Content = [{
The ``_Nonnull`` nullability qualifier indicates that null is not a meaningful value for a value of the ``_Nonnull`` pointer type. For example, given a declaration such as:
.. code-block:: c
int fetch(int * _Nonnull ptr);
a caller of ``fetch`` should not provide a null value, and the compiler will produce a warning if it sees a literal null value passed to ``fetch``. Note that, unlike the declaration attribute ``nonnull``, the presence of ``_Nonnull`` does not imply that passing null is undefined behavior: ``fetch`` is free to consider null undefined behavior or (perhaps for backward-compatibility reasons) defensively handle null.
}];

def TypeNullableDocs : Documentation {

The ``_Nullable`` nullability qualifier indicates that a value of the ``_Nullable`` pointer type can be null. For example, given:

def TypeNullUnspecifiedDocs : Documentation {

The ``_Null_unspecified`` nullability qualifier indicates that neither the ``_Nonnull`` nor ``_Nullable`` qualifiers make sense for a particular pointer type. It is used primarily to indicate that the role of null with specific pointers in a nullability-annotated header is unclear, e.g., due to overly-complex implementations or historical factors with a long-lived API.
}];
}
def NonNullDocs : Documentation {
let Category = NullabilityDocs;
let Heading = "nonnull";
let Content = [{
The ``nonnull`` attribute indicates that some function parameters must not be null, and can be used in several different ways. It's original usage (`from GCC <https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#Common-Function-Attributes>`_) is as a function (or Objective-C method) attribute that specifies which parameters of the function are nonnull in a comma-separated list. For example:
.. code-block:: c
extern void * my_memcpy (void *dest, const void *src, size_t len)
__attribute__((nonnull (1, 2)));
Here, the ``nonnull`` attribute indicates that parameters 1 and 2
cannot have a null value. Omitting the parenthesized list of parameter indices means that all parameters of pointer type cannot be null:
.. code-block:: c
extern void * my_memcpy (void *dest, const void *src, size_t len)
__attribute__((nonnull));
Clang also allows the ``nonnull`` attribute to be placed directly on a function (or Objective-C method) parameter, eliminating the need to specify the parameter index ahead of type. For example:
.. code-block:: c
extern void * my_memcpy (void *dest __attribute__((nonnull)),
const void *src __attribute__((nonnull)), size_t len);
Note that the ``nonnull`` attribute indicates that passing null to a non-null parameter is undefined behavior, which the optimizer may take advantage of to, e.g., remove null checks. The ``_Nonnull`` type qualifier indicates that a pointer cannot be null in a more general manner (because it is part of the type system) and does not imply undefined behavior, making it more widely applicable.
}];
}
def ReturnsNonNullDocs : Documentation {
let Category = NullabilityDocs;
let Heading = "returns_nonnull";
let Content = [{
The ``returns_nonnull`` attribute indicates that a particular function (or Objective-C method) always returns a non-null pointer. For example, a particular system ``malloc`` might be defined to terminate a process when memory is not available rather than returning a null pointer:
.. code-block:: c
extern void * malloc (size_t size) __attribute__((returns_nonnull));
The ``returns_nonnull`` attribute implies that returning a null pointer is undefined behavior, which the optimizer may take advantage of. The ``_Nonnull`` type qualifier indicates that a pointer cannot be null in a more general manner (because it is part of the type system) and does not imply undefined behavior, making it more widely applicable
