baa8acd546 Include stddef.h before including cxxabi.h
On FreeBSD 10.0, size_t needs to be defined before including cxxabi.h.
Currenty HAVE_CXXABI_H is not defined on FreeBSD because of that reason.
This patch teaches cmake and configure how to include it.

bdc3a5b99a Add llvm-go tool.
This tool lets us build LLVM components within the tree by setting up a
$GOPATH that resembles a tree fetched in the normal way with "go get".

It is intended that components such as the Go frontend will be built in-tree
using this tool.

1496d41753 Do not add -gsplit-dwarf to LLVM_DEFINITIONS.
This would cause the flag to appear in the output of "llvm-config --cppflags",
which should contain only preprocessor flags. The -gsplit-dwarf flag in
particular can cause problems with certain downstream users such as cgo.

14e55b16df Teach lit to filter the host LDFLAGS down from the build system and into
the CGO build environment. This lets things like -rpath propagate down
to the C++ code that is built along side the Go bindings when testing
them.

7c771b0293 Revert r220174, "Always use -Wl,-gc-sections on our build."
It dropped required functions for plugins with gnu ld 2.20 and 2.21.

  Failing Tests (1):
      LLVM :: Feature/load_module.ll

  Hello: bin/opt: symbol lookup error: lib/LLVMHello.so: undefined symbol: _ZN4llvm11raw_ostream13write_escapedENS_9StringRefEb

  Failing Tests (1):
      Clang :: Frontend/plugins.c

  error: unable to load plugin 'lib/PrintFunctionNames.so': 'lib/PrintFunctionNames.so: undefined symbol: _ZN5clang15PluginASTAction6anchorEv'

I think we should inspect linker's version or behavior to introduce --gc-sections for --export-dynamic.

FreeBSD/NetBSD, where we have dl_iterate_phdr and can learn the
main executable name without argv0 (it will be possible on BSD systems
after http://reviews.llvm.org/D5693 lands). #ifdef-out the code for
all the rest Unix systems.

ee3948fdbe Use llvm-symbolizer to symbolize LLVM/Clang crash dumps.
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.

dadfd4f0a7 Fix misinterpretation of CMake rule found by a CMake warning (related to CMP0054).
lldb sets the variable SHARED_LIBRARY to 1, which breaks this conditional,
because older versions of CMake interpret

  if ("${t}" STREQUAL "SHARED_LIBRARY")

as meaning

  if ("${t}" STREQUAL "1")

in this case. Change the conditional so it does the right thing with both old
and new CMakes.

aa55210555 Attempt to fix PR20884
This fixes the generation of broken LLVMExports.cmake file by
the Autoconf/Makefile build system when --enable-shared is passed to
configure.

When --enable_shared is passed the Makefile.rules does not set the
LLVMConfigLibs variable which cmake/modules/Makefile previously relied
on. Now it runs the llvm-config command itself to get the library names.

This still isn't perfect because the generated LLVM targets refer to the
static libraries and not the shared library but that is much larger
problem to fix.

901166c939 Enabling LLVM & Clang to be cross-compiled using CMake from a single configuration command line
The basic idea is similar to the existing cross compilation support. A directory must be configured to build host versions of tablegen tools and llvm-config. This directory can be user provided (and configured), or it can be created during the build. During a build the native build directory will be configured and built to supply the tablegen tools used during the build. A user could also explicitly provide the tablegen executables to run on the CMake command line.

f51fbcbb36 [CMake][Win32.DLL] Let llvm_add_library(SHARED) link dependent libraries as PRIVATE.
For example, c-index-test.exe requires just libclang.dll (its import library).
When libraries in libclang were not PRIVATE but PUBLIC, c-index-test required libraries transitive by libclang.

Note, on mingw with BUILD_SHARED_LIBS, library dependencies would become more strict.
In principle, required libraries should be "required in its source file".

This will help to detect missing dependencies.

2bd8e0cde3 Prospective -fsanitize=memory build fix following r212586
This -f group flag appears to influence linker flags, breaking the usual rules
and causing CMake's link invocation to fail during feature detection due to
missing link dependencies (msan_*).

Let's forcibly add it for now to get things the way they were before feature
detection started working.

d87c2fc2e3 CMake: make __DATE__, __TIME__ etc. macro usage an error
When LLVM_ENABLE_TIMESTAMPS has been disabled we can prevent the preprocessor
from embedding dates, times and file timestamps.

There are a few motivations for this:

  1) Validate the recent CMake feature detection bugfix from LLVM r212586 with
     a flag that's not actually available everywhere.

  2) Dogfood clang's new -Wdate-time warning from r210511 when bootstrapping.

  3) Encourage reproducible builds.

b1d6b8ea7d CMake: fix compiler feature detection
add_flag_if_supported() and add_flag_or_print_warning() were effectively
no-ops, just returning the value of the first result (usually
'-fno-omit-frame-pointer') for all subsequent checks for different flags.

Due to the way CMake caches feature detection results, we need to provide
symbolic variable names which will persist the cached results. This commit
fixes feature detection using these two macros.

The feature checks now run and get stored correctly, and the correct output can
be observed in configure logs:

  -- Performing Test C_SUPPORTS_FPIC
  -- Performing Test C_SUPPORTS_FPIC - Success
  -- Performing Test CXX_SUPPORTS_FPIC
  -- Performing Test CXX_SUPPORTS_FPIC - Success

7ca91f97cc [CMake] Introduce LLVM_ENABLE_PLUGINS as an internal option. BUILD_SHARED_LIBS may not control enable/disable plugins.
FIXME: Make this configurable.

FIXME: "ENABLE_SHARED" doesn't make sense, since it is used just for plugins. We may rename it.
I introduced config.enable_shared in r120273.
