[lldb][Process/FreeBSDKernel] Remove libfbsdvmcore support (#181283)
Due to libfbsdvmcore, adding new features requires modifying both
`ProcessFreeBSDKernelFVC` and `ProcessFreeBSDKernelKVM` which also
requires testing on both. This is highly inefficient while the user base
of fvc is currently invisible since most package manager don't ship
libfbsdvmcore with LLDB.
There is still demand for cross-platform kernel dump debugging. This
will be implemented in future either by cloning and embedding kvm
interface into LLDB or unifying dump formats to ELF core with
minidump-to-elf conversion tool on FreeBSD side.

[mlir][tosa] Use 0 values for the dense resource in tosa-narrow-* tests (#182321)
For the test portability between little-endian and big-endian, just use
zeros as the dense resource values. It doesn't test the actual narrowing
but tests that the other conversions went well.
[NFC][SPIRV] Replace removeFromParent by eraseFromParent
`removeFromParent` doesn't deallocate the resources associated with the
`MachineInstruction`.
I was not able to remove all the uses of `removeFromParent` in the file.
llvm: Delete bugpoint
For crash reduction, I don't think it does anything that llvm-reduce
can't. Pass pipeline reduction also has a separate reduction script.
The main thing there isn't a replacement tool is the miscompilation
reducer, but I'm not sure that's actually functioned for years.
There are still some references to bugpoint in various comments
and pieces of documentation that don't all necessarily make sense
to replace or remove. In particular there are a few passes documented
as "only for bugpoint", but I've left those alone in case they are
useful for manual reductions.
[AArch64][llvm] Remove `+xs` gating for `tlbip *nxs` instructions (#179435)
A recent specification update has removed `FEAT_XS` gating for `tlbip *nxs`
instructions. It remains gated on `FEAT_XS` for `tlbi *nxs` instructions.
[emacs] Rework tablegen mode
This commit reworks tablegen-mode to be derived from prog-mode and
removes a lot of the manual work that define-derived-mode does for you
these days, along with fixing other lints (such as an over-long
summary).
This is a major version bump because td-decorators-face has been
renamed to tablegen-decorators-face in order to not pollute other
namespaces.
AMDGPU: Strip sign bit operations on llvm.amdgcn.trig.preop uses (#179712)
The instruction ignores the sign bit, so we can find the magnitude
source. The real library use has a fabs input which this avoids.
stripSignOnlyFPOps should probably go directly into PatternMatch in some
form.
[NFC][emacs] Fix emacs lints in the LLVM and MLIR modes (#182074)
This mainly involved explicitly declaring minimum emacs versions for
setq-local and adding a lexical-binding annotaton.
The commit also removes some workarounds from the MLIR mode for Emacs 23
(!).
docs: Delete incorrect code generation section of HowToSubmitABug (#182315)
I've never used this. Based on the description here, I'm assuming
it relied on the C backend, which was removed in 2012.
tools: Remove untested PluginLoader includes (#117644)
As far as I can tell there are 2 parallel plugin mechanisms.
opt -load=plugin does not work, and is ignored. opt -load-pass-plugin
does work. PluginLoader.h forces a static definition of the "load"
cl::opt into included TUs. Delete the cases with no tests.
[mlir][acc] Add attributes for parallelism dimensions (#182209)
As OpenACC gets lowered to eventually mapping to GPU (via GPU dialect),
we need to track parallelism assignment which we can use in how
variables get privatized, how barriers and synchronizations are inserted
to ensure appropriate OpenACC execution model, and for loop
work-sharing. This adds GPUParallelDimAttr and GPUParallelDimsAttr for
this.
[WebAssembly] Fix SELECT_CC lowering for reference types (#181622)
SELECT_CC nodes with externref or funcref return types were not being
expanded, causing "Cannot select" errors during instruction selection.
This adds SELECT_CC to the list of operations that should be expanded
for reference types, similar to how it's already handled for scalar
types (i32, i64, f32, f64). This allows the SELECT_CC to be lowered to a
SELECT node, which already has instruction patterns defined in
WebAssemblyInstrRef.td.
[X86] combineCMov - fold CMOV(LOAD(PTR0),LOAD(PTR1)) -> LOAD(CMOV(PTR0,PTR1)) (#182084)
As discussed on #182021 - if we have equivalent simple loads (chain,
addressspace etc.), just with different pointers then we can select
between the pointers directly and perform just a single load, which in
most cases will avoid branching.
A future patch might be able to further simplify some (mainly stack?)
address math with CMOV(X,ADD(X,C1)) -> ADD(X,CMOV(0,C1)) /
CMOV(ADD(X,C0),ADD(X,C1)) -> ADD(X,CMOV(C0,C1))

[MLIR] Fix a crash in CollapseLinalgDimensions (#181715)
This patch fixes #181610
Added a check in areDimSequencesPreserved()
to verify that each map is a projected permutation before calling
isDimSequencePreserved().
If a map is not a projected permutation, the
function returns false (dimension sequences cannot be preserved in
non-projected-permutation maps).
[mlir][Interface] Allow scalar operands and require ranked shaped operands in IndexingMapOpInterface (#179072)
This change adjusts `IndexingMapOpInterface::verifyImpl`: Scalars are
allowed as operands (treated as rank-0), vectors remain allowed,
unranked tensors/memrefs are rejected with explicit diagnostics.
Fixes https://github.com/llvm/llvm-project/issues/179043
