x11-wm/plasma6-kwin: backport upstream patch
to fix a regression that made it impossible to turn
offscreens through kscreen in some setups.
(cherry picked from commit 3e947f94758b29071ab7f52c4bfd71d4600b2827)
[libc] Clean up pthread.yaml (#178327)
Remove pthread.h.def and use pure generation. Fix YAML records
for standards to correct syntax and remove redundancies.
Don't declare NULL, which is not specified for <pthread.h>.
Do declare PTHREAD_NULL.
[libc++] Don't define _LIBCPP_INSTRUMENTED_WITH_ASAN for hwasan builds (#178278)
This macro should not be defined if `LLVM_USE_SANITIZER` is `HWAddress`.
[MTE][Darwin] This patch extends support for the stack frame history buffer to Darwin. (#178049)
Darwin reserves slot 231 for storing a pointer to the history ring
buffer. It also uses bits 60-62 to store the size of the ring buffer

[AMDGPU][SIInsertWaitcnts] Cleanup: Remove WaitEventMaskForInst member variable (#178030)
The event mask is constant and target dependent it should be accessed
through the WCG object.
mvc: support throwing exceptions in importRecordSet(.., $data_callback, ..) for importCsv() to add validation on the input data.

[libc] [math] Refactor fsqrtl to be header-only (#176169)
This PR refactors fsqrtl to be header only as discussed. No functional
change intended. Test and build files were updated as required by the
refactor
Fixes #175335
[StaticDataLayout][MemProf] Annotate string literal hotness by making use of data access profiles. (#178333)
The change is gated under a new option
`memprof-annotate-string-literal-section-prefix` so we can flag-gate it
for rollout purposes.
A follow-up PR https://github.com/llvm/llvm-project/pull/178336/changes
updates the codegen pass to reconcile the hotness similar to the
reconciliation for other global variables.
[NFC] update doc comment on `setLoopEstimatedTripCount` (#178091)
See [this
discussion](https://github.com/llvm/llvm-project/pull/174896#issuecomment-3802361713)
prompted by PR #174896.
A 0-0 encoding in branch weights is invalid (the probability of an edge
is computed as a fraction where the denominator is the sum of the
weights and the numerator is its - the edge's - weight). So BPI actually
handles it as 1-1, which then results in raising the BFI of the loop
body that's meant to be cold.
The aforementioned PR addressed this, but didn't update the doc comment.
[mlir][xegpu] Add initial support for layout conflict handling. (#173090)
This PR adds initial support for layout conflict resolution in XeGPU.
Layout conflict occurs when some op's use point expects a different
layout than what the op can currently provide. This conflict needs to be
resolved by adding certain other xegpu ops.
Initially, We only focus conflict handling at tensor desc use points.
[EarlyIfConversion] Add analysis for data-dependent conditional branches(#174457)
Add infrastructure to identify conditional branches on values loaded from
memory. Such branches are likely to be harder to predict accurately since
branch history (probably) provides little useful information.
This analysis walks the def-use chain from the branch condition to find
loads that feed into it. Several cases are excluded from consideration:
- Loads from constant pools (predictable values)
- Dereferenceable invariant loads (loop-invariant)
- Branches with biased probability (null checks, etc.)
- Loads not "close in program time" to the branch (must be in the same
basic block with no intervening calls)
The analysis is disabled by default behind -enable-early-ifcvt-data-dependent.
