[Docs][AMDGPU] availability/visibility in addrspace(3)
addrspace(3) on AMDGPU corresponds to LDS, which is a fast memory directly
accessed by all threads in a workgroup (there is no intervening cache). Thus,
any accesses to this addrspace have built-in availability and visibility at
"workgroup" scope.
flnews-snapshot: Update to 1.4.0pre3
Bug fixes:
- FILTER: Avoid double free in filter rule constructor if regular
expression for string could not be compiled (reported by
Michael Uplawski, patch from Robert Kuhn assisted by Claude AI).
New features and improvements:
- FILTER: Display line number in scorefile (if debug mode is enabled).
AMDGPU: Add supports-wgp subtarget feature
Whether the hardware supports WGP (work-group processor) execution mode is a
fixed per-GPU capability, distinct from the per-kernel cumode selection. Add
a dedicated feature instead of inferring from the generation and instructions.

authpf(8) read_config() should chop off trailing white space
if administrator mistakenly types into configuration file
anchor=authpf_test
where 'authpf_test' is followed by white space, the authpf(8)
is going to use anchor 'authpf_test ' instead of the 'authpf_test'
which is defined in pf.conf(5) as 'anchor authpf_test/*'

[clang] Improve diagnostics around constexpr limits (#212091)
1) Mention the limit in the "constexpr evaluation hit maximum step
limit" diagnostic as well
2) Move the "use -fconstexpr-steps" instruction to its own note so we
can reuse it for two different diagnostics
For
```c++
struct S {
constexpr S() {}
};
constexpr S foo[1'500'000] = {};
```
we used to emit
```console
array.cpp:1028:13: error: constexpr variable 'foo' must be initialized by a constant expression
1028 | constexpr S foo[1'500'000] = {};
| ^ ~~

[test] Migrate Hexagon/PowerPC thunk tests to the default thunk order (#212693)
Drop -z nosort-thunks (added by #211721 to keep creation order) and
update expectations to the default order: forward thunks sorted by
descending destination.
[Clang][X86] Introduce Clang ABI Gate for MSVC alignment (#210305)
On x86_64-windows-msvc after 8ecec455183f, clang applies the MSVC
size-based global-alignment scheme (Microsoft64BitMinGlobalAlign) and
does not apply the Sys V "large array" alignment increase. Users may
want to preserve the earlier ABI for compatibility with objects produced
by older clang releases.
Gate this behavior on the Clang ABI compatibility level. When
`-fclang-abi-compat=22` (or lower) is in effect,
MicrosoftX86_64TargetInfo restores LargeArrayMinWidth/LargeArrayAlign to
128 and getMinGlobalAlign skips the Microsoft64BitMinGlobalAlign step,
matching the older alignment choices.
Assisted by Claude (Anthropic).

Revert "[AArch64] Enable Spillage Copy Elimination by default" (#211572)
Reverts llvm/llvm-project#186093
Issue https://github.com/llvm/llvm-project/issues/206839 shows that
EliminateSpillageCopies is not currently ready to be enabled by default
on AArch64. https://github.com/llvm/llvm-project/pull/207169 was raised
to fix the issue, but concerns were raised around complexity of the
function and change. Until a suitable solution can be found,
EliminateSpillageCopy will be disabled on AArch64 by default.
For those who wish to still use the pass, `-enable-spill-copy-elim=true`
will ensure the pass is run.
