As opposed to GCC/GAS the default ABI for Mips64 is n64.
Compatibility bit should be set if o32 ABI is used when targeting Mips64.

The code was missing the case for aggregate parameters and
hence was emitting them as .b0 type. Also fixed a couple
of comments.

This improves the fix committed at revision 199683 adding the
following new target specific combine rules:

1) fold (v4i32: vselect <0,0,-1,-1>, A, B) ->
        (v4i32 (bitcast (movsd (v2i64 (bitcast A)), (v2i64 (bitcast B))) ))

2) fold (v4f32: vselect <0,0,-1,-1>, A, B) ->
        (v4f32 (bitcast (movsd (v2f64 (bitcast A)), (v2f64 (bitcast B))) ))

3) fold (v4i32: vselect <-1,-1,0,0>, A, B) ->
        (v4i32 (bitcast (movsd (v2i64 (bitcast B)), (v2i64 (bitcast A))) ))

4) fold (v4f32: vselect <-1,-1,0,0>, A, B) ->
        (v4f32 (bitcast (movsd (v2i64 (bitcast B)), (v2i64 (bitcast A))) ))

When simplifycfg moves an instruction, it must drop metadata it doesn't know
is still valid with the preconditions changes. In particular, it must drop
the range and tbaa metadata.

The patch implements this with an utility function to drop all metadata not
in a white list.

The llvm_headers_do_not_build project needs to be excluded from the default build, otherwise it gets built (at least in Visual Studio 2013).

Thanks to chapuni200000 for help with this in IRC!

Mozilla and WebKit seem to use a space after @property (verified by
grepping their codebases) so we turn this on there as well.

Change by Christian Legnitto. Thank you!

[ASan] Reinstate ASAN_LOW_MEMORY, which has nothing to do with signal handling and thus should not be moved to common.

Express the strto* interceptors though macros. This removes a lot of
duplicate code and fixes a couple of copypasto bugs (where "res" was declared of
a different type than the actual return type). Also, add a few more interceptors
for strto*_l.

Verification of base addresses is difficult as the independent blocks pass may
introduce aliasing that was not there during scop detection. As a midterm
solution -polly-codegen-scev will remove the need for the independent blocks
pass. For now, we do not verify at compile time that the independent blocks pass
does not make the base addresses loop invariant. Disabling this just removes
one of the multiple safety layers we have. We still can check for correctness
in our regression tests.

llvm-svn: 200315

Array base addresses need to be invariant in the region considered. The base
address has to be computed outside the region, or, when it is computed inside,
the value must not change with the iterations of the loops. For example, when a
two-dimensional array is represented as a pointer to pointers the base address
A[i] in an access A[i][j] changes with i; therefore, such regions have to be
rejected.

Make sure that we don't introduce illegal build_vector dag nodes
when trying to fold a sign_extend of a build_vector.

This fixes a regression introduced by r200234.
Added test CodeGen/X86/fold-vector-sext-crash.ll
to verify that llc no longer crashes with an assertion failure
due to an illegal build_vector of type MVT::v4i64.

Thanks to Ilia Filippov for spotting this regression and for
providing a reproducible test case.

[CMake] llvm_update_compile_flags(name) doesn't require source files. TARGET PROPERTY SOURCES has them.

This change is a part of refactoring intended to have common signal handling behavior in all tools.
Note that this particular change doesn't enable use_sigaltstack support in every tool.

At present, this handles .tc (error) and needs to be expanded to deal properly with .machine

They seems to be unused, but cause maintenance pain.

Arguments and return values must always be marshalled as for the base

It is the final step to deprecate contextual CMAKE_CXX_FLAGS.

[CMake] Enhance llvm_update_compile_flags(name sources) to handle LLVM_REQUIRES_EH and LLVM_REQUIRES_RTTI.

LLVM_REQUIRES_EH implies LLVM_REQUIRES_RTTI. It is as same behavior as Makefile.rule's.
llvm/examples/ExceptionDemo is affected. (It was built with -fno-rtti.)

For MSVC, Remove flags like "/EHsc /GR" in HandleLLVMOptions, or CL.EXE complains with flags like "/GR /GR-".

llvm_update_compile_flags() updates source file property if the target contains *.c.
COMPILE_FLAGS in target properties affects both C++ and C!

LLVM_NO_RTTI is deprecated. It was introduced by me and was my mistake.

llvm-svn: 200301

llvm-svn: 200300

With this tweaks, also unittests are compiled with -ffunction-sections.

It's hard to control contextual CMAKE_CXX_FLAGS. We should get rid of twiddling it as possible.
