CMAKE_SOURCE_DIR is not the right directory if llvm is included in
another cmake project. PROJECT_SOURCE_DIR is always the same and should
be used instead.
Instead of having different names for the same Lit feature accross code
bases, use the same name everywhere. This NFC commit is in preparation
for a refactor where all three projects will be using the same Lit
feature detection logic, and hence it won't be convenient to use
different names for the feature.

Add 96-bit, 160-bit and 256-bit AReg classes to match VReg and SReg.
NFC as far as I know, but it may avoid weird legalization problems.

After D78301 MC no longer emits a relocation for this case. Change to use
.inst and .reloc to synthesize the same instruction and relocation. One
more test case I missed.
Prior to this patch, llvm-objdump would only look in the last section
(according to the section header table order) that matched an address
for a symbol when identifying the target symbol of a call or branch
operation. If there are multiple sections with the same address, due to
some of them being empty, it did not look in those, even if the symbol
couldn't be found in the first section looked in.
This patch causes llvm-objdump to look in all sections for possible
candidate symbols. If there are multiple possible symbols, it picks one
from a non-empty section, if possible (as that is more likely to be the
"real" symbol since functions can't really be in emptiy sections),
before falling back to those in empty sections. If all else fails, it
falls back to absolute symbols as it did before.

The `Offset` field is used to set the file offset of a program header.
In a normal object it should not be greater than the minimal offset
of sections included into segment.
This patch adds a check for that and adds tests.

Finding the loop tripcount is the first crucial step in preparing a loop for
tail-predication, and this adds a debug message if a tripcount cannot be found.
And while I was at it, I added some more comments here and there.

Summary:
Moving this out of the monorepo for consistency with other editor plugins.
There's no version lock with clangd itself, and we never ran tests with lit.
The first version from the new repo has been published.

Summary:
Use a nested symbol to identify the kernel to be invoked by a `LaunchFuncOp` in the GPU dialect.
This replaces the two attributes that were used to identify the kernel module and the kernel within seperately.
Differential Revision: https://reviews.llvm.org/D78551
Summary:
Use the shortcu `kernel` for the `gpu.kernel` attribute of `gpu.func`.
The parser supports this and test cases are easier to read.

Fix a broken test case in the `invalid.mlir` lit test case.
`expect` was missing its `e`.

Summary:
Rationale:
Using the --debug-only flag requires a debug build. Also, the debug output is not always consistent over different builds.
This change avoids all problems by just testing the generated assembly for AVX.

We also need to lock the LLVMDialect mutex when initializing
LLVM targets or destroying llvm modules concurrently. Added another

The number of different access location kinds we track is relatively
small (8 so far). With this patch we replace the DenseMap that mapped
from index (0-7) to the access set pointer with an array of access set
pointers. This reduces memory consumption.
No functional change is intended.

This patch exploits rldimi instruction for patterns like
`or %a, 0b000011110000`, which saves number of instructions when the
operand has only one use, compared with `li-ori-sldi-or`.

We were disabling verification for no reason in a bunch of places; just
turn it on.
At this point, there are two key places where we don't run verification:
during register allocation, and after addPreEmitPass. Regalloc probably
isn't worth messing with; it has its own invariants, and verifying
afterwards is probably good enough. For after addPreEmitPass, it's
probably worth investigating improvements.
Summary: Switch to pc-relative lookup of the xray handler function to avoid text relocations.
