[lldb] Don't add remap entries for empty segments (#183651)
There are some binaries in the shared cache with a zero-length segment,
or segments who get mapped to lldb address 0 to indicate a failure. Do
not add entries to the VirtualDataExtractor's LookupTablefor those -
they
are not readable.

[MLIR][XeGPU] XeGPU Layout adds support for fractional-subgroup-size vector (#183434)
This PR enhances the layout assignment for XeGPU load/store operations
to handle vector size smaller than subgroup size.
Say for vector[4], in case of lane_data=[1], lane_layout=[4] and
inst_data=[4].
The fractional-subgroup-size vector support is required to support the
cross-subgroup reduction case. The number of participant subgroups in
reduction can be small, so it causes each subgroup needs to reduce a
small vector size, often a fraction of subgroup size.
Most layout-based subgroup distribution patterns support
fraction-subgroup-size without no change except a few: reduction,
insert/extract, constant. We don't expect ND operations (like
load_nd/store_nd/dpas) accept fractional-subgroup-size vector.
Revert "[mlir-tblgen] Remove `namespace {}` around OpDocGroup (#182721)" (#183458)
Reverts #182721, it's not needed after #183457.
It was a work around for #182720.
This reverts commit a0f344f69d7eb5d87dd78c628a196a3a7440e792.
[SafeStack] Allow -fsanitize-minimal-runtime with -fsanitize=safestack (#183644)
SafeStack does not require a full sanitizer runtime, so it should be
compatible
with the minimal runtime flag.
[mlir][vector] Fix fold result for empty vector.mask with no results (#180345)
This PR fixes `foldEmptyMaskOp` to return `failure` when folding an
empty vector.mask whose terminatorhas no operands. Previously this case
returned success without producing any folded results, which violates
the folding contract. Fixes #177825.

- Documentation organization and navigation can be specialized by
language family, to allow users to interact with documentation in a
way that is tailored to that language family. This is currently used
by Rhombus.
- The `for` form and its variants accept an `#:on-length-mismatch`
specifier. 3.18 Iterations and Comprehensions: for, for/list, ...
- DrRacket improves the GUI for choosing color schemes.
- DrRacket has curved syntax arrows. The degree of curvature indicates
the relative left- or right-displacement of the arrow's target.
- DrRacket's "Insert Large Letters" uses characters that match the
comment syntax of the buffer's language, making it useful (and fun!)
in Rhombus.
- The `exn-classify-errno` maps network and filesystem error numbers
on various platforms to posix-standard symbols, to enable more
portable code. 10.2 Exceptions
- The behavior of Racket BC on certain character operations (most
notably `eq?`) is changed to match that of Racket CS, with a small

[DenseMap] Add memory barrier for sanitizers in getInlineBuckets/getLargeRep (#183457)
Add a compiler memory barrier to prevent optimizations from triggering
false positives on partially poisoned buckets in (HW)ASan.
Fixes #182720.

[Sema] Fix crash on invalid operator template-id (#181404)
Add checks in GetNameFromUnqualifiedId to handle invalid TemplateId
cases safely. This avoids a crash when handling an invalid template-id
during error recovery and allows normal error reporting to continue.
Fixes #177549
