The findMIPSMultilibs is too long. One more reason for splitting is to

Previously if you did e.g.
$ clang -march=haswell -x cuda foo.cu
we would pass "-march=haswell -march=sm_20" down to the ptxas tool.

The two patches together enable clang to support targets like
"x86_64-pc-linux-musl" and build binaries against musl-libc instead of
glibc. This make it easy for clang to work on some musl-based systems
like Alpine Linux and certain flavors of Gentoo.

We now have a cmake option to change the default: ENABLE_LINKER_BUILD_ID.
The reason is that build-id is fairly expensive, so we shouldn't impose
it in the regular edit/build cycle.
This is similar to gcc, that has an off by default --enable-linker-build-id
option.

Exherbo has an alternative file system layout to accommodate multiarch. The

CodeSourcery toolchain is a standalone toolchain which always uses

As The default CMAKE install prefix is /usr/local ( https://cmake.org/cmake/help/v3.0/variable/CMAKE_INSTALL_PREFIX.html ),
sudo ninja install ends up installing clang, LLVM and libcxx under /usr/local.
In development scenario, when clang is run from the build location it will not
find libcxx at neither (build location)/../include/c++ nor /usr/include/c++.
This patch lets development clang find system installed libcxx without adding
-isystem /usr/local/include/c++. Also addresses the FIXME by explaining the
use-case for these include paths.

Summary:
The MIPS IAS can now pass 'ninja check-all', recurse, build a bootable linux
kernel, and pass a variety of LNT testing.
Unfortunately we can't enable it by default for 64-bit targets yet since the N32
ABI is still very buggy and this also means we can't enable it for N64 either
because we can't distinguish between N32 and N64 in the relevant code.

clang support on Haiku is lagging a bit, and missing on x86_64.
This patch updates support for x86 and add support for x86_64. It should
apply directly to trunk and it's harmless in the sense that it only

- Don't consider "/etc/lsb-release" to be Ubuntu only.
- Detect SL, too.
- Only add "--no-add-needed" for RHEL7 (or Fedora), not for RHEL6
(that's what the compilers shipped with RHEL do).
- removed RHEL4 which is now four years past EOL and certainly incapable
of building or running any recent version of llvm/clang.

Some distros with ten years of support ship an old gcc but later offer
more recent versions for installation in parallel. These versions are
typically not only needed for the compilation of llvm/clang, but also to
properly use the clang binary that comes out.
Clang already searches /usr at runtime for the most recent installation
of gcc. This patch appends paths for add-on installations of gcc in
RHEL.

Summary:
This patch adds a new driver warning -Wincompatible-sdk which notifies the user when they are mismatching the version min options and the sysroot.
The patch works by checking the sysroot (if present) for an SDK name, then matching that against the target platform. In the case of a mismatch it logs a warning.

Over the last month we've been testing SafeStack extensively. As far as
we know, it works perfectly fine. That why I'd like to see us having
this enabled by default for CloudABI.
This change introduces a getDefaultSanitizers() function that toolchains
can use to specify which sanitizers are enabled by default. Once all
flags are processed, only flags that had no -fno-sanitize overrides are
enabled.
Extend the thests for CloudABI to test both the default case and the
case in which we want to explicitly disable SafeStack.

This is the clang driver part of the change to embedded bitcode. This
includes:
1. -fembed-bitcode option which breaks down the compilation into two
stages. The first stage emits optimized bitcode and the second stage
compiles bitcode into object file.
2. -fembed-bitcode-marker option which doesn't really break down to
two stages to speedup the compilation flow.
3. pass the correct linker flag to darwin linker if tool chains supports
embedded bitcode.

C++ programs compiled for profiling (using `-pg`) should be linked with
`-lc++_p` (or `-lstdc++_p`, depending on the `-stdlib=` setting), not
with the regular C++ libraries.
Add a `FreeBSD::AddCXXStdlibLibArgs()` override to handle this, and add
a test case for it. While here, extend the test case for the proper
passing of -lm and -lm_p.
