llvm-svn: 286094

We shouldn't access past the end of an array, even if we think that the
layout of the struct containing the array is always what we expect. The
compiler is free to optimize away the stores as undefined behavior, and
in fact, GCC 6.2.1 claims it will do exactly this.

[AVX-512] Remove masked pmovzx/pmovsx builtins and autoupgrade them to selects and native zext/sext.

This mostly reuses earlier autoupgrade support for the sse and avx equivalents. Just needed to add the code to add the select.

llvm-svn: 286092

[X86] Remove GCCBuiltins from cvtsi2ss/cvtsi2sd/cvtss2sd intrinsics as they aren't used by clang. Add TODOs to remove these and some other unused intrinsics.

llvm-svn: 286091

llvm-svn: 286090

[AVX-512] Remove 128/256 masked pshufb intrinsics. Autoupgrade them to legacy intrinsics and a select.

llvm-svn: 286089

I will probably submit a lot of small trivial changes
like this over the coming weeks.  The end goal is to
convert Options::SetOptionValue to take the option arg
as a StringRef, but doing so in one pass would be a huge
mess of disparate changes just to satisfy the compiler,
and with a high risk of breaking.  So I'm going to do
this in small pieces, changing seemingly random things
here and there until the final change to the signature
of Options::SetOptionValue() can be done trivially.

Also delete a comment I forgot to delete.

llvm-svn: 286085

Cmake has not recognized that Hexagon.td has a new dependency in
HexagonPatterns.td. All changes to that file were not visible to
the build bots.

llvm-svn: 286083

This handles the last case of the builtin function calls that we would
generate code which differed from Microsoft's ABI.  Rather than
generating a call to `__pow{d,s}i2` we now promote the parameter to a
float or double and invoke `powf` or `pow` instead.

Addresses PR30825!

llvm-svn: 286082

llvm-svn: 286081

The clr/set/toggle-bit instructions (with the bit index given as an
immediate operand) had both, custom selection code that generated them,
and selection patterns at the same time. The selection patterns were
not used, because the custom selection code was executed first.
This patch removes the custom code in favor of the selection patterns.
The custom code handled 64-bit registers as well with an immediate bit
index, and so new patterns were added to implement that.

It was also the same case for the instruction "Rd += asr(Rs, Rt)",
except that the custom code did not offer any additional functionality,
and was simply removed.

llvm-svn: 286080

Remove unnecessary type casts in patterns.

llvm-svn: 286079

Give simpler or more meaningful names to pat frags and xforms.

llvm-svn: 286078

Remove unnecessary C++ functions for SDNode transforms. Move more
pat frags to files where they are used.

llvm-svn: 286077

Add pat frags for any-, sign-, and zero-extensions.

In preparation for demandedelts support

llvm-svn: 286074

[AVX-512] Remove intrinsics for 128/256-bit masked variable shift. Instead upgrade them to a select and the older AVX2 intrinsic.

llvm-svn: 286073

[AVX-512] Remove intrinsics for 128/256-bit masked shift by immediate. Instead upgrade them to a select and the older SSE/AVX2 intrinsic.

llvm-svn: 286072

llvm-svn: 286071

[AVX-512] Remove intrinsics for 128/256-bit masked shift by single element in xmm. Instead upgrade them to a select and the older SSE/AVX2 intrinsic.

llvm-svn: 286070

[AVX-512] Remove a 512-bit test cases from the avx512vl test file. It already exists in the avx512f test file.

llvm-svn: 286069

In preparation for demandedelts support

llvm-svn: 286068

Don't regenerate a zeroable element mask with computeZeroableShuffleElements when its already available.

llvm-svn: 286067

No functional change intended.

llvm-svn: 286066

This fixes casting warning and removes the need of that cast at all.

llvm-svn: 286065

llvm-svn: 286064

[X86] Add a few more fptoui test cases to the vec_fp_to_int.ll. The codegen for these test cases will be improved for AVX512 in a future commit.

llvm-svn: 286063

Summary:
This kill various depreacated API related to attribute :
 - The deprecated C API attribute based on LLVMAttribute enum.
 - The Raw attribute set format (planned to be removed in 4.0).

llvm-svn: 286062

Patch switches computing of --build-id hash to tree.

This is the way when input data is splitted by chunks,
hash is computed for each one in threaded/non-threaded way.
At the end hash is conputed for result tree.

With or without -threads the result hash is the same.

Summary:
Fixes PR30869.

In D25977 I meant to change all functions that care about lifetime. I
changed constructors, factory functions, but I missed member/free
functions that return new instances. This patch changes them.

[AVX-512] Add avx512vl command line to the fpext test and add -show-mc-encoding to show where we aren't using EVEX instructions.

llvm-svn: 286058

[AVX-512] Lower AVX cvtpd2ps intrinsic to ISD::FP_ROUND so it can use EVEX instruction when available.

llvm-svn: 286057

[AVX-512] Lower SSE/AVX cvtdq2ps intrinsics directly to ISD::SINT_TO_FP so they can use EVEX instructions when available.

llvm-svn: 286056

[AVX-512] Add -show-mc-encoding to legacy vector intrinsic tests so we can see when VEX or EVEX encoded instructions are being emitted. Make sure the tests all have an avx2 command line and an skx command line.
