Reid Kleckner 397a17bfeb Don't run explicit-modules-missing-files.cpp on Windows
It is flaky due to inability to remove files with open handles.  We
could paper over it with rm -f, but then the file would still be
present.

This is more evidence to me that we should roll our own 'rm'
implementation in LLVM.

Vedant Kumar 2f079be789 [ARM] Fix MachO CPU Subtype selection
This patch makes the Darwin ARM backend take advantage of TargetParser.  It
also teaches TargetParser about ARMV7K for the first time. This makes target
triple parsing more consistent across llvm.

Martell Malone 7ccda3c38b Windows ARM: ignore calling conventions as described on MSDN
Summary:

accepted but ignored on ARM and X64.
https://msdn.microsoft.com/en-us/library/984x0h58.aspx

MSDN also says cdecl is also accepted and typically ignored
This patch brings ARM in line with how we ignore them for X64

Sanjay Patel ed502905f7 [x86] fix allowsMisalignedMemoryAccess() implementation
This patch fixes the x86 implementation of allowsMisalignedMemoryAccess() to correctly
return the 'Fast' output parameter for 32-byte accesses. To test that, an existing load
merging optimization is changed to use the TLI hook. This exposes a shortcoming in the
current logic and results in the regression test update. Changing other direct users of
the isUnalignedMem32Slow() x86 CPU attribute would be a follow-on patch.

Without the fix in allowsMisalignedMemoryAccesses(), we will infinite loop when targeting
SandyBridge because LowerINSERT_SUBVECTOR() creates 32-byte loads from two 16-byte loads
while PerformLOADCombine() splits them back into 16-byte loads.

Reid Kleckner 89d994367a [windows] Fix or XFAIL remaining portable test failures and enable them
Summary:
This involved various fixes:

- Move a test that uses ulimit to Posix.

- Add a few "REQUIRES: shell" lines to tests using backtick subshell
  evaluation.

- The MSVC CRT buffers stdio if the output is a pipe by default. Some
  tests need that disabled to avoid interleaving test stdio with asan
  output.

- MSVC headers provide _alloca instead of alloca (go figure), so add a
  portability macro to the two alloca tests.

- XFAIL tests that rely on accurate symbols, we need to pass more flags
  to make that work.

- MSVC's printf implementation of %p uses upper case letters and doesn't
  add 0x, so do that manually.

- Accept "SEGV" or "access-violation" reports in crash tests.

Rafael Espindola dbaf0498a9 Revert "Centralize the information about which object format we are using."
This reverts commit r245047.

It was failing on the darwin bots. The problem was that when running

./bin/llc -march=msp430

llc gets to

  if (TheTriple.getTriple().empty())
    TheTriple.setTriple(sys::getDefaultTargetTriple());

Which means that we go with an arch of msp430 but a triple of
x86_64-apple-darwin14.4.0 which fails badly.

That code has to be updated to select a triple based on the value of
march, but that is not a trivial fix.

Rafael Espindola 90eb70c8a7 Centralize the information about which object format we are using.
Other than some places that were handling unknown as ELF, this should
have no change. The test updates are because we were detecting
arm-coff or x86_64-win64-coff as ELF targets before.

It is not clear if the enum should live on the Triple. At least now it lives
in a single location and should be easier to move somewhere else.

With this patch only the name is set. I will set the other fields shortly.

For now the table doesn't include local symbols. This is equivalent to using
--discard-all with gnu ld. This is OK for now since the symbols are not
needed for execution and for testing symbol resolution we only need the
global symbols.

Alexey Bataev b08f89ffc1 [OPENMP] Fix for http://llvm.org/PR24371: Assert failure compiling blender 2.75.
blender uses statements expression in condition of the loop under control of the '#pragma omp parallel for'. This condition is used several times in different expressions required for codegen of the loop directive. If there are some variables defined in statement expression, it fires an assert during codegen because of redefinition of the same variables.
We have to rebuild several expression to be sure that all variables are unique.

Manuel Klimek 54042e743c Add structed way to express command line options in the compilation database.
Currently, arguments are passed via the string attribute 'command',
assuming a shell-escaped / quoted command line to extract the original
arguments. This works well enough on Unix systems, but turns out to be
problematic for Windows tools to generate.

This CL adds a new attribute 'arguments', an array of strings, which
specifies the exact command line arguments. If 'arguments' is available
in the compilation database, it is preferred to 'commands'.

Currently there is no plan to retire 'commands': there are enough
different use cases where users want to create their own mechanism for
creating compilation databases, that it doesn't make sense to force them
all to implement shell command line parsing.
