[InstCombine] Preserve fdiv metadata on fneg folds (#179157)
Copy metadata from the original fdiv when folding fneg into fdiv or
hoisting fneg above fdiv. This keeps !fpmath (and other metadata)
intact, preventing !fpmath loss seen in libclc tanpi function. fneg only
flips sign bit, so it does not affect precision.
[clang-tidy][NFC] Fix incorrect `list.rst` modification by `add_new_check.py` (#179297)
We have observed unexpected and extensive modifications to `list.rst` in
a few Pull Requests. After some investigation I found that
`add_new_check.py` was misclassifying existing checks, leading to
instability in the generated documentation list.
More specifically:
- The script relies on `http-equiv=refresh` meta tags to identify alias
checks, which is missing in several existing checks, causing them to be
incorrectly listed as regular checks.
- The script fails to detect fix-its in checks that use CamelCase helper
methods.
With this patch, running `add_new_check.py` now generates a stable and
correct `list.rst` consistent with the actual codebase state.
[BOLT] Get symbol for const island referenced across func by relocation (#178988)
When handling relocation in one function referencing code or
data defined in another function, we should check if relocation
target is constant island or not, and get the referenced symbol
accordingly for both cases.
workflows/commit-access-review: Use a GitHub App access token instead of llvmbot
This replaces the use of an access token associated with the llvmbot
account with one that is generated by a GitHub App. This is slightly
better, because it eliminates the need to periodically rotate the
llvmbot tokens, which is difficult to do, since it requires sharing
a password and 2fa code among all the admins.
The tokens generated by the app automatically expire after an hour, and
the private key that is used to request it can be easily rotated by
an LLVM Organization owner. Also, since a single private key can
be used to generate many tokens, there is only one secret to rotate
instead of many.
acpi: Post/pre device suspend/resume eventhandlers
These eventhandlers are called after suspending the device tree and
before resuming it. This is useful for PMC (power management controller)
drivers.

acpi_spmc: Register SPMC suspend/resume routines
SPMC suspend runs after the device tree is suspended using the
acpi_post_dev_suspend eventhandler, and SPMC resume runs before the
device tree is resumed using the acpi_pre_dev_suspend eventhandler.

[mlir][MemRef] Make fold-memref-alias-ops use memref interfaces
This replaces the large switch-cases and operation-specific patterns
in FoldMemRefAliashops with patterns that use the new
IndexedAccessOpInterface and IndexedMemCopyOpInterface, which will
allow us to remove the memref transforms' dependency on the NVGPU
dialect.
This does also resolve some bugs and potential unsoundnesses:
1. We will no longer fold in expand_shape into vector.load or
vector.transfer_read in cases where that would alter the strides
between dimensions in multi-dimensional loads. For example, if we have
a `vector.load %e[%i, %j, %k] : memref<8x8x9xf32>, vector<2x3xf32>`
where %e is
`expand_shape %m [[0], [1], [2. 3]] : memref<8x8x3x3xf32> to 8x8x9xf32,
we will no longer fold in that shape, since that would change which
value would be read (the previous patterns tried to account for this
but failed).
2. Subviews that have non-unit strides in positions that aren't being

[mlir] Add [may]updateStartingPosition to VectorTransferOpInterface
This commit adds methods to VectorTransferOpInterface that allow
transfer operations to be queried for whether their base memref (or
tensor) and permutation map can be updated in some particular way and
then for performing this update. This is part of a series of changes
designed to make passes like fold-memref-alias-ops more generic,
allowing downstream operations, like IREE's transfer_gather, to
participate in them without needing to duplicate patterns.
[mlir] Implement indexed access op interfaces for memref, vector, gpu, nvgpu
This commit implements the IndexedAccessOpInterface and
IndexedMemCopyInterface for all operations in the memref and vector
dialects that it would appear to apply to. It follows the code in
FoldMemRefAliasOps and ExtractAddressComputations to define the
interface implementations. This commit also adds the interface to the
GPU subgroup MMA load and store operations and to any NVGPU operations
currently being handled by the in-memref transformations (there may be
more suitable operations in the NVGPU dialect, but I haven't gone
looking systematically)
This code will be tested by a later commit that updates
fold-memref-alias-ops.
