Otherwise users get messages from CheckAtomic about missing libatomic
instead of a sensible message that says "use GCC 4.7 or newer".
I structured the change along the lines of HandleLLVMStdlib.cmake, so
that the standalone build of Clang still gets the compiler version
check.

CMAKE_EXE_LINKER_FLAGS is a string. Appending a flag using list(APPEND) introduces an extra

Building clang with -fno-pie generates slightly faster code. In my not-very-rigorous testing I saw about a 4% speed up using the clang test-suite sources.

On the average user's system, those libraries will not be compiled with
MSan. Prior to this change, the LLVM test suite was full of false
positives from calls from third party libraries to MSan interceptors
like strlen.
We can remove this check if MSan ever grows a suppression mechanism
similar to TSan's.

If we don't have sys/wait.h and we're on a unix system there's no way
that several of the llvm tools work at all. This includes clang.
Just remove the configure and cmake checks entirely - we'll get a

This patch changes linkage with dbghlp.dll for clang from static (at load time)
to on demand (at the first use of required functions). Clang uses dbghlp.dll
only in minor use-cases. First of all in case of crash and in case of plugin load.
The dbghlp.dll library can be absent on system. In this case clang will fail
to load. With lazy load of dbghlp.dll clang can work even if dbghlp.dll
is not available.

ctypes 0.3 and earlier contains an interface-definig bug:
its ptr_of_raw_address accepts Int64 and not Nativeint. ctypes 0.4
was not released during the 3.6 cycle, and because of that, LLVM 3.6
was released with ctypes 0.3 as a dependency, which now breaks
the build on modern ctypes.

The gold binary is not required to build the plugin. All that is

This works in a similar way to the gold plugin tests. We search for a compatible
linker on $PATH and use it to run tests against our just-built libLTO. To start

NOTE: This patch intentionally breaks the build. It attempts
to resubmit r230083, but with some debug logging in the CMake

correctly disable the DIA tests when DIA is not available.
After a sufficient number of bots fail, this patch will either
be reverted or, if the cause of the failure becomes obvious,
a fix submitted with the log statements removed.

a gold binary explicitly. Substitute this binary into the tests rather
than just directly executing the 'ld' binary.
This should allow folks to inject a cross compiling gold binary, or in
my case to use a gold binary built and installed somewhere other than
/usr/bin/ld. It should also allow the tests to find 'ld.gold' so that
things work even if gold isn't the default on the system.
I've only stubbed out support in the makefile to preserve the existing
behavior with none of the fancy logic. If someone else wants to add
logic here, they're welcome to do so.

This change modifies fatal signal handler used in LLVM tools.
Now it attempts to find llvm-symbolizer binary and communicates
with it in order to turn instruction addresses into
function/file/line info entries. This should significantly improve
stack traces readability in Debug builds.
This feature only works on selected platforms (including Darwin
and Linux). If the symbolization fails for some reason, signal
handler will fallback to the original behavior.

clang's own CMake setup handles this as of r210308.
The CMAKE_CROSSCOMPILING special-case will no longer be hard-coded. This was
clearly site-specific to someone's local configuration and should be passed in
at configure time if needed with e.g. -DLIBXML2_LIBRARIES=... (the libxml2
target I tried here doesn't even support liblzma so it's *way* off).

Replace the crufty build-time configure checks for program paths with
equivalent runtime logic.
This lets users install graphing tools as needed without having to reconfigure
and rebuild LLVM, while eliminating a long chain of inappropriate compile
dependencies that included GUI programs and the windowing system.
Additional features:
* Support the OS X 'open' command to view graphs generated by any of the
Graphviz utilities. This is an alternative to the Graphviz OS X UI which is
no longer available on Mountain Lion.
* Produce informative log output upon failure to indicate which programs can
be installed to view graphs.

This commit starts with a "git mv ARM64 AArch64" and continues out
from there, renaming the C++ classes, intrinsics, and other
target-local objects for consistency.
"ARM64" test directories are also moved, and tests that began their
life in ARM64 use an arm64 triple, those from AArch64 use an aarch64
triple. Both should be equivalent though.
This finishes the AArch64 merge, and everyone should feel free to
continue committing as normal now.

following CMake options have been added that control what targets are

SPHINX_OUTPUT_HTML
SPHINX_OUTPUT_MAN
If LLVM_BUILD_DOCS is enabled then the enabled docs-llvm-* targets will
be built by default and if ``make install`` is run then docs-llvm-html
and docs-llvm-man will be installed (tested on Linux only).
The add_sphinx_target function is in its own file so it can be included
by other projects that use Sphinx for their documentation.

This adds a second implementation of the AArch64 architecture to LLVM,
accessible in parallel via the "arm64" triple. The plan over the

ISSUE:
On Ubuntu 12.04 LTS, arc4random is provided by libbsd.so, which is a
transitive dependency of libedit. If a system had libedit on it that
was implemented in terms of libbsd.so, then the arc4random test,
previously implemented as a linker test, would succeed with -ledit.
However, on Ubuntu this would also require a #include <bsd/stdlib.h>.
This caused a build breakage on configure-based Ubuntu 12.04 with
libedit installed.
FIX:
This fix changes configure to test for arc4random by searching for it
in the standard header files. On Ubuntu 12.04, this test now properly
fails to find arc4random as it is not defined in the default header
locations. It also tweaks the #define names to match the output of the
header check command, which is slightly different than the linker
function check #defines.
I tested the following scenarios:
(1) Ubuntu 12.04 without the libedit package [did not find arc4random,
as expected]
(2) Ubuntu 12.04 with libedit package [properly did not find
arc4random, as expected]
(3) Ubuntu 12.04 with most recent libedit, custom built, and not
dependent on libbsd.so [properly did not find arc4random, as
expected].
(4) FreeBSD 10.0B1 [properly found arc4random, as expected]

r200744 moved this into cmake/config-ix.cmake, so that it would happen very
early in the build process. However, standalone builds of Clang and other
external projects never include this file (which is correct).
Now, -stdlib=libc++ and the LLVM_COMPILER_IS_GCC_COMPATIBLE option are
both set in a new include file, HandleLLVMStdlib, which is included by
both config-ix.cmake and HandleLLVMOptions.cmake. This preserves existing
behavior for projects relying on HandleLLVMOptions and still does the
right thing for builds of LLVM itself.
llvm-svn: 200811
If LLVM_ENABLE_LIBCXX is specified, we should append -stdlib=libc++ to build
flags as early as possible, in particular, before we check for header presence
(as -stdlib=libc++ modifies header lookup rules). Otherwise we can find a header
at configure time (w/o -stdlib=libc++) but fail to find it at build time
(with -stdlib=libc++). See PR18569 for more details.

This library will be used by clang-query. I can imagine LLDB becoming another
client of this library, so I think LLVM is a sensible place for it to live.
It wraps libedit, and adds tab completion support.
The code is loosely based on the line editor bits in LLDB, with a few
improvements:
- Polymorphism for retrieving the list of tab completions, based on
the concept pattern from the new pass manager.
- Tab completion doesn't corrupt terminal output if the input covers
multiple lines. Unfortunately this can only be done in a truly horrible
way, as far as I can tell. But since the alternative is to implement our
own line editor (which I don't think LLVM should be in the business of
doing, at least for now) I think it may be acceptable.
- Includes a fallback for the case where the user doesn't have libedit
installed.
Note that this uses C stdio, mainly because libedit also uses C stdio.
