libunwind is known to work on FreeBSD i386, amd64 (x86_64) and arm64.
It is the unwinder provided by the base system on all of those
architectures.

In OpenCL the kernel function and non-kernel function has different calling conventions.
For certain targets they have different argument ABIs. Also kernels have special function
attributes and metadata for runtime to launch them.

The blocks passed to enqueue_kernel is supposed to be executed as kernels. As such,
the block invoke function should be emitted as kernel with proper calling convention and
argument ABI.

This patch emits enqueued block as kernel. If a block is both called directly and passed
to enqueue_kernel, separate functions will be generated.

These select the same instruction as the non-bitcasted pattern. So this provides no additional value.

llvm-svn: 315799

[X86] Remove unnecessary bitconverts as the root of patterns for zero extended VCVTPD2UDQZ128rr and VCVTTPD2UDQZ128rr.

We don't need a bitconvert as a root pattern in these cases. The types in the other parts of the pattern are sufficient to express the behavior of these instructions.

llvm-svn: 315798

This matches the patterns we have for the SSE/AVX version.

This is a prerequisite for D38714.

I believe these were added incorrectly under the belief that the load size was smaller than the input register size, but that's not true.

[X86] Add an additional isel pattern to CVTDQ2PDrm/VCVTDQ2PDrm to enable load folding without the peephole pass.

This pattern is already used in AVX512VL version of these instructions. Though AVX512VL version is missing other patterns.

This reverts r315697 and my ill-fated attempts to fix it on Windows.
I'll try again when I get access to a Windows machine.

"No such file or directory: C:\\...\\tests\\Output\\shared-output.py.tmp/Output/Shared/SHARED.tmp"

And yet other forward-slashes don't seem to be causing the same
problem. I'll see if I can get ahold of a Windows machine to poke at
this directly later.

Currently llvm assembler emits parsing error for valid IR assembly

alloca i32, i32 9, addrspace(5)
when alloca addr space is 5.

This patch fixes that.

Summary:
This patch removes the `verifyNCD` check.

The reason for this is that the other checks are sufficient to prove or disprove correctness of any DominatorTree, and that `verifyNCD` doesn't provide (in my option) better error messages then the other ones.
Additionally, this should give a (small) improvement to the total verification time, as the check is O(n), and checking the sibling property takes O(n^3).

There were two copies of the logic needed to construct a line stats
object for each line in a range: this patch brings it down to one. In
the future, this will make it easier for IDE clients to display coverage
in-line in source editors. To do that, we just need to move the new
LineCoverageIterator class to libCoverage.

[globalisel][tablegen] Fix an unused variable warning caused by a typo (corrected OtherInsnID->OtherOpIdx).

The tests were passing by luck since the instruction ID and operand index happened to be the same.

If the variable construction can be constant evaluated it doesn't have
side effects, so removing it is always safe. We only try to evaluate
variables that are unused, there should be no impact on compile time.

The function sanitizer only checks indirect calls through function
pointers. This excludes all non-static member functions (constructor
calls, calls through thunks, etc. all use a separate code path). Don't
emit function signatures for functions that won't be checked.

Apart from cutting down on code size, this should fix a regression on
Linux caused by r313096. For context, see the mailing list discussion:
