- added detection of libdevice bitcode file and API to find one appropriate for the GPU we're compiling for.
- pass additional cc1 options for linking with detected libdevice bitcode
- added -nocudalib to prevent automatic linking with libdevice
- added test cases to verify new functionality

In order to compile a CUDA file clang must be able to find
include files for both both host and device.
This patch passes AuxToolchain to AddPreprocessingOptions and
uses it to add include paths for the opposite side of compilation.
We also must be able to find CUDA include files. If the driver
found CUDA installation, it adds appropriate include path
to CUDA headers. This can be disabled with '-nocudainc'.
- Added include paths for the opposite side of compilation.
- Added include paths to detected CUDA installation.
- Added -nocudainc to prevent adding CUDA include path.
- Added test cases to verify new functionality.

Clang needs to know target triple for both sides of compilation so that
preprocessor macros and target builtins from both sides are available.
This change augments Compilation class to carry information about
toolchains used during different CUDA compilation passes and refactors
BuildActions to use it when it constructs CUDA jobs.
Removed DeviceTriple from CudaHostAction/CudaDeviceAction as it's no
longer needed.

"-arch armv7k" is only normally used with a watchos target, but Clang doesn't
stop you from giving a "-miphoneos-version-min" option too, converting the
triple to "thumbv7k-apple-ios". In this case the backend will decide to use
SjLj exceptions, so Clang needs to agree so it can create the correct
predefines.
Fortunately, there's a handy function to make the decision for us now.

This reverts commit r253269.
This leads to assert / segfault triggering on the following reduced example:
float foo(float U, float base, float cell) { return (U = 2 * base) - cell; }

Last time, this caused two Windows buildbots and a single ARM buildbot to fail.
I XFAIL'd the failing test on win32,win64 machines in order to see if the ARM
buildbot complains again.

Summary:
For clarity and ease of maintenance, I suggest porting this test
to use the same tooling as the rest of the tests.

This currently changes the default toward the more historic -Av8/-Av9,
but as discussed with James Y Knight, consistency is for now more
important than figuring out which default CPU each OS should be using.

When adding profiling instrumentation, use libclang_rt.profile_tvos.a
for TVOS targets and libclang_rt.profile_watchos.a for WatchOS targets.
I've also fixed up a comment and added an assert() that prevents us from
defaulting to an incorrect platform.

applied correctly. Pass down the correct -A flag when not using IAS.
The latter is limited to NetBSD targets in this commit.

The -meabi flag to control LLVM EABI version.
Without '-meabi' or with '-meabi default' imply LLVM triple default.
With '-meabi gnu' sets EABI GNU.
With '-meabi 4' or '-meabi 5' set EABI version 4 and 5 respectively.
A similar patch was introduced in LLVM.

This sets the mostly expected Darwin default ABI options for these two

This patch should add support for almost all command-line options and

This reverts commit r251695. Debug is meant to be done off tree, not use the buildbots
experiments. I'll help investigate this problem off trunk.

This should be a NFC for every toolchain other than mips-mti-linux (where we
print the list of directories searched for crt files). It will soon be
reverted once we hit the clang-cmake-armv7-a15-selfhost-neon buildbot.

The original commit in r249137 added the mips-mti-linux toolchain. However,
the newly added tests of that commit failed in few buildbots. This commit
re-applies the original changes but XFAILs the test file which caused
the buildbot failures. This will allow us to examine what's going wrong
without having to commit/revert large changes.

Since r249754 MemorySanitizer should work equally well for PIE and
non-PIE executables on Linux/x86_64.
Beware, with this change -fsanitize=memory no longer adds implicit
-fPIE -pie compiler/linker flags on Linux/x86_64.
This is a re-land of r250941, limited to Linux/x86_64 + a very minor
refactoring in SanitizerArgs.

Summary:
Similar to rL248426 (which was a followup to rL248379 and rL248424), add the
required libraries for OpenMP on the linker command line, and update the test
case.
