The artifact combiner searches for the uses of G_MERGE_VALUES for
unmerge/trunc that need further combining. This also needs to handle
the vector merge opcodes the same way. This fixes leaving behind some
pairs I expected to be removed, that were if the legalizer is run a
second time.
isWriteAtEndOfFunction needs to check all memory uses of Def, which is
much more expensive than getting the underlying objects in practice.
Switch the call order, as recommended by the TODO, which was added as

This shaves off a bit of compile-time.
Pin the test to use -enable-npm-optnone.
Before, optnone wasn't implemented under NPM, so the LPM and NPM runs produced different IR. Now with -enable-npm-optnone, that is no longer necessary.

This fails due to the clang invocation running at -O0, producing an optnone function.
Then even with -O2 in the later invocations, LoopVectorizePass doesn't run on the optnone function.
So split this into an -O0 run and an -O2 run.

Rename the existing expectedFailure to expectedFailureIfFn to better
describe its purpose and provide an overload for
unittest2.expectedFailure in decorators.py.
Currently the code does not account for the fact that getDomMemoryDef
can be called with ScanLimit == 0, if we reached the limit while
processing an earlier access. Also tighten the check a bit more and bump
the scan limit now that it is handled properly.
In some cases, this brings a 2x speedup in terms of compile-time.
Only link against Python3_LIBRARY when LLDB_ENABLE_PYTHON is true. We

We may have an SGPR->VGPR copy if a totally uniform pointer

Also hack around a bug in MUBUF matching which would incorrectly use

The comment says that TestMultipleDebuggers was XFAILed because it was
failing nondeterministically in which case it should be skipped not
failed (as XPASS will cause the test suite to fail).
The reason it fails is because it was not marked as a no-debug-info test
case. I've ran the test in a loop and it has been passing consistently.
Let's enable it and see if the bots agree, if not we can skip it.
This function is available on llvm::Type and has been used by some clients of

- Add OpPassManager::getAnalysis() to always call the base getAnalysis() with OpT.
- With this, an OperationPass can call getAnalysis<> using an analysis type that

If the same stream object is used for multiple compiles, the PAL metadata from eariler compilations will leak into later one. See https://github.com/GPUOpen-Drivers/llpc/issues/882 for how this is happening in LLPC.
No tests were added because multiple compiles will have to happen using the same pass manager, and I do not see a setup for that on the LLVM side. Let me know if there is a good way to test this.

This patch implements the handling for the R_PPC64_PCREL_OPT relocation as well
as the GOT relocation for the associated R_PPC64_GOT_PCREL34 relocation.
On Power10 targets with PC-Relative addressing, the linker can relax
GOT-relative accesses to PC-Relative under some conditions. Since the sequence
consists of a prefixed load, followed by a non-prefixed access (load or store),
the linker needs to replace the first instruction (as the replacement
instruction will be prefixed). The compiler communicates to the linker that
this optimization is safe by placing the two aforementioned relocations on the
GOT load (of the address).
The linker then does two things:
- Convert the load from the got into a PC-Relative add to compute the address
relative to the PC
- Find the instruction referred to by the second relocation (R_PPC64_PCREL_OPT)
and replace the first with the PC-Relative version of it
It is important to synchronize the mapping from legacy memory instructions to
their PC-Relative form. Hence, this patch adds a file to be included by both
the compiler and the linker so they're always in agreement.

Legacy implementation of the LLVM dialect in MLIR contained an instance of
llvm::Module as it was required to parse LLVM IR types. The access to the data
layout of this module was exposed to the users for convenience, but in practice
this layout has always been the default one obtained by parsing an empty layout
description string. Current implementation of the dialect no longer relies on
wrapping LLVM IR types, but it kept an instance of DataLayout for
compatibility. This effectively forces a single data layout to be used across
all modules in a given MLIR context, which is not desirable. Remove DataLayout
from the LLVM dialect and attach it as a module attribute instead. Since MLIR
does not yet have support for data layouts, use the LLVM DataLayout in string
form with verification inside MLIR. Introduce the layout when converting a
module to the LLVM dialect and keep the default "" description for
compatibility.
This approach should be replaced with a proper MLIR-based data layout when it
becomes available, but provides an immediate solution to compiling modules with
different layouts, e.g. for GPUs.
This removes the need for LLVMDialectImpl, which is also removed.

Existing implementation always aborts on syntax errors in a DataLayout

only abort in the top-level parsing function instead.
