This patch introduces lowering of the OpenMP parallel operation to LLVM
IR using the OpenMPIRBuilder.

Functions topologicalSort and connectPhiNodes are generalised so that
they work with operations also. connectPhiNodes is also made static.

Lowering works for a parallel region with multiple blocks. Clauses and
arguments of the OpenMP operation are not handled.

Summary: Fixed an implicit definition warning by including <string.h>. Also fixed run-time assertions that the return value of strxfrm_l calls is less than the buffer size by increasing the size of the referenced buffer.

Currently, a transformation like pow(2.0, x) -> exp2(x) copies the pow
attribute list verbatim and applies it to exp2. This works out fine
when the attribute list is empty, but when it isn't clang may error due
due to the mismatch.

The source function and destination don't necessarily have anything
to do with one another, attribute-wise. So it makes sense to remove
the attribute lists (this is similar to what IPO does in this
situation).

This was discovered after implementing the `noundef` param attribute.

This reverts commit 9649c209. See
discussion on the llvm-commits thread: if it's OK to preserve the
location when sinking a call, it's probably OK to always preserve the
location.

This is exposed by https://reviews.llvm.org/D83486.
When the host is UTF8, we may get n >10, causing assert failure.
Increase the buffersize to support UTF-8 to C conversion.

Check that the implicit cast from `id` used to construct the element
variable in an ObjC for-in statement is valid.

This check is included as part of a new `objc-cast` sanitizer, outside
of the main 'undefined' group, as (IIUC) the behavior it's checking for
is not technically UB.

The check can be extended to cover other kinds of invalid casts in ObjC.

That's just asking for ODR violations. Also drop a call to lower()
that's not needed.

https://reviews.llvm.org/D78411 introduced test changes which relied on
the ability to strip debugify metadata even if module-level metadata is
missing. This introduces a more targeted test for that ability.

Fix the requirements for that test.

Summary: The native alignment may generally not be used when lowering a vector.transfer to the underlying load/store operation. This revision fixes the unmasked load/store alignment to match that of the masked path.

This is intended to address a compile-time regression from
1eddce41. A SmallPtrSet was
replaced with a SetVector there, which had an unexpected large
compile-time impact. It turns out that this structure is getting
swapped a lot, and previously this used an optimized std::swap()
specialization for SmallPtrSet. Now it ends up using the default,
triple-move based implementation, which is much more expensive.

This patch (partly) addresses the issue by specializing std::swap()
for SetVector.

[MLIR] Change ODS collective params build method to provide an empty default value for named attributes

- Provide default value for `ArrayRef<NamedAttribute> attributes` parameter of
  the collective params build method.
- Change the `genSeparateArgParamBuilder` function to not generate build methods
  that may be ambiguous with the new collective params build method.
- This change should help eliminate passing empty NamedAttribue ArrayRef when the
  collective params build method is used
- Extend op-decl.td unit test to make sure the ambiguous build methods are not
  generated.

Right now slicing would assert if an operation with multiple results is in the

Per the Vulkan's SPIR-V environment spec, "for the OpSRem and OpSMod
instructions, if either operand is negative the result is undefined."
So we cannot directly use spv.SRem/spv.SMod if either operand can be
negative. Emulate it via spv.UMod.

Because the emulation uses spv.SNegate, this commit also defines
spv.SNegate.

This is in preparation for the 'development' mode advisor. We currently
want to track what the default policy's decision would have been, this
refactoring makes it easier to do that.

Character literals can be formatted using octal or hex escapes for
non-ascii characters. This is so that the program can be unparsed for
either pgf90 or gfortran to compile. But modfiles should not be affected
by that -- they should be consistent.

This changes causes modfiles to always have character literals formatted
with octal escapes.

Place the ssa.copy instructions for assumes after the assume,
instead of before it. Both options are valid, but placing them
afterwards prevents assumes from being replaced with assume(true).
This fixes https://bugs.llvm.org/show_bug.cgi?id=37541 in NewGVN
and will avoid a similar issue in SCCP when we handle more
predicate infos.

Result might not be exactly the same as under GVN, but all the
desired transforms are made.

Add an -xfail.ll suffix to tests marked XFAIL, so these files can
