[TargetParser][Clang] Parse Intel GPU architecture names (#229247)
Add support for Intel GPU names in --offload-arch.
#222072 added the mapping from a detected GPU version to its name. This
PR adds the reverse mapping, needed when a user names a GPU through
--offload-arch. Previously, clang recognized only the hardcoded name
bmg_g21.
The shared Intel GPU list now recognizes device names such as
xe-bmg-g21, compatibility names such as xe-dg2, aliases for products on
the same GPU IP such as xe-arl-u, and numeric names such as xe_20.1.0.
The driver keeps each name as given, so it reaches ocloc unchanged.
bmg_g21 is replaced by xe-bmg-g21.
Building one device job per IGCA target follows once IGCA targets are an
OffloadArch (#227468). Selecting the SPIR-V target from an Intel GPU
name and diagnosing unknown names follow in #229248 and #229249.

[SPARC] Fix the f128 one and ueq compares without hard quad (#234315)
_Q_cmp returns 0 for equal, 1 for less, 2 for greater, and 3 for
unordered. Masking with 3 does not do anything. fcmp one should return
true when ordered and not equal, so add 1 and mask with 2.
```
1 001 equal - false
2 010 less - true
3 011 greater - true
4 100 unordered - false
```
fcmp ueq is the complement.
Found when building glibc.

[MemProf] Include callsite/alloc index in duplicate clone hash (#236790)
The ThinLTO backend computes a hash of each function clone's callsite
clone numbers and allocation hints, in order to detect clones that are
duplicates of an earlier clone (or the original function), which are
then emitted as aliases instead of separate copies. However, the hash
only included the non-default values, not which callsite or allocation
they were for. Therefore, for example, a clone whose callsites call
callee clones [1, 0] had the same hash as one with [0, 1], and was
incorrectly emitted as an alias of the latter, causing its callers to
call the wrong callee clones.
Include the index of each callsite or allocation, along with a tag
distinguishing the two kinds, in the hash.

[X86] Remove dead code from LowerADDSUBO_CARRY. Improve variable names. NFC (#236830)
The illegal type checks are unreachable as this code is only called
after type legalization.
Move a getValue(1) call earlier and give it its own variable name.
This matches the review feedback I received when copying the current
code structure to M68k in #235569.

[libc][math] Return a floating NaN from the cbrtf16 signaling path (#236478)
Return a floating quiet NaN from cbrtf16's signaling-NaN path instead of

The ordinary cube-root approximation is unchanged.

[OpenMP] Mostly remove experimental taskgraph support from runtime (#194046)

removal part.

- Various fixes (Alexei Starovoitov):
- Use emit_rsb_call() to call bpf_unwind_target() in x86 JIT to fix
objtool warning during the build
- Fix scalar evolution: clear delta of a widened register, don't
widen a pointer to a buffer, don't clamp a register whose type
changed in the loop, and reset the range of a clamped packet
pointer

mbuf: Match TCP RSS hash types exactly
RSS hash types are encoded values, not independent flags. The bitmask
check in M_HASHTYPE_ISHASH_TCP() also accepts UDP, address-only and opaque
hash types, causing the syncache to retain them instead of falling back
to a software TCP hash.
Compare against the three TCP four-tuple hash types after masking the
inner-header flag. Keep the existing macro interface and use an inline
helper to preserve single evaluation of its argument.
Add ATF coverage for all 256 hash-type byte values, including inner-header
hashes, and verify single evaluation of the mbuf argument.

[SPIR-V] Fix and enforce minimum versions of decoration operands (#229058)
Version lookups decoded the hex table values as decimal, so no minimum
version was ever met, also add the missing minimum versions for
UniformId (1.4), BufferBlock (1.3), AlignmentId and MaxByteOffsetId
(1.2)
Requirement contract for operands without capabilities:
- Version only: the target version must meet it
- Version and extension: a met version is enough and the extension is
not emitted (e.g. NoSignedWrap at 1.4+), otherwise an enabled extension
stands in for the unmet version
[AMDGPU] Retire dead uses before adding defs in GCNDownwardRPTracker (#228294)
Before this patch, the downward order for each instruction was the
following: advanceToNext() added an instruction's defs to the live set
while the uses that died at that instruction were still in it. Then it
sampled MaxPressure. At the next step, advanceBeforeNext() called
retireDeadOperands to drop the dead uses and defs. Then it sampled
MaxPressure. But this order could lead to inflated register pressure
reporting that could adversely affect the scheduler stages. This was
additionally inconsistent with the add/drop order of the generic
tracker.
The changes in this patch apply the transfer function in the order the
generic tracker uses in RegPressureTracker::advance(). Retire the lanes
that die at the instruction first, then add its defs. Early-clobber defs
are the exception. PHIs are skipped because nothing dies there. All of
these are now done by advanceToNext().
advanceBeforeNext() now only drops dead def lanes, the uses having been

[ASan][test] Keep Posix/waitid.cpp overflow within stack redzone (#236825)
`waitid.cpp` previously pointed `siginfo_t *si` completely past a
12-byte local `int x[3]`, causing the kernel `waitid` syscall to write
128 bytes beyond `x`'s right stack redzone.
On AArch64 without UAR (such as Android, where
`detect_stack_use_after_return` defaults to `false`), at `-O3` the
64-byte ASan stack frame sits immediately below `main`'s saved `[x29,
x30]` whenever ASLR aligns `x29` to 32 bytes (~50% of runs), so `waitid`
overwrote the caller frame pointer on the stack before
`COMMON_INTERCEPTOR_WRITE_RANGE` ran. Commit `be8b3f0c2204` previously
attempted to disable the test on AArch64 with `UNSUPPORTED: aarch64`,
which did not match compiler-rt lit's `aarch64-target-arch` feature.
Size `x` to `sizeof(siginfo_t)` and offset `si` by `argc * sizeof(void
*)` so the overflow stays inside ASan's right stack redzone without
corrupting the caller frame record, and remove the ineffective `aarch64`
exclusion.

[clang][docs] Fix the __block import example in the Block ABI (#226626)
The helpers in this example passed `BLOCK_FIELD_IS_BYREF |
BLOCK_BYREF_CALLER`, but clang passes only `BLOCK_FIELD_IS_BYREF` there,
as the rest of the document says.
Also fixed the field names, the type of `forwarding`, the helpers of the
`int` variable and a missing comma, to match what clang generates.
Checked with `clang -cc1 -rewrite-objc -fblocks` from clang 3.0 on this
example; current clang passes the same flag.
