[SYCL] Correct emission status reporting for function templates declared with SYCL attributes. (#185522)
Commit cf6cc662eeee2b1416430f517850be9032788e39 ([OpenMP][SYCL] Improve
diagnosing of unsupported types usage) customized
`Sema::getEmissionStatus()` to return `Emitted` for a function declared
with the `sycl_kernel` attribute during device compilation. That change
is appropriate, but was inserted before a check for a dependent context
and resulted in `Emitted` being returned instead of `TemplateDiscarded`
for templated functions declared with the attribute. That appears to be
incorrect; templated functions are still discarded.
The customization was extended to include the `sycl_kernel_entry_point`
and `sycl_external` attributes in commit
23e4fe040b67e2dd419652830a87093a93ea1a97 ([SYCL] SYCL host kernel launch
support for the sycl_kernel_entry_point attribute). Those additions are
appropriate, but the effect on templated functions (as opposed to their
instantiations) resulted in the incorrect status being observed in a
downstream fork of Clang.
This change corrects `Sema::getEmissionStatus()` to once again
unconditionally return `TemplateDiscarded` for templated functions.
[lldb][test] Fix TestLongjmp on Linux (#185464)
Patch fixes llvm.org/pr20231.
The original test was expecting clock() to return 0 when stepping in
debugger which in reality can never happen.
[SPIR-V] Make SPIRVModuleAnalysis::MAI a non static member (#160956)
Otherwise multiple translation units in the same process could run into
ID reuse collisions cause invalid SPIR-Vs to be generated due to having
multiple definition for the same SPIR-V SSA value.

NAS-140066 / 26.0.0-BETA.2 / Fix WebSocket connection drops caused by nginx proxy_read_timeout (by mgrimesix) (#18413)
### Problem
WebSocket connections to the middleware API were being silently dropped
during long-running jobs, causing API clients to receive
ClientException('WebSocket connection closed with code=None,
reason=None').
The root cause is nginx's proxy_read_timeout, which defaults to 60
seconds. This timeout governs how long nginx will wait for data from the
upstream (middlewared) before closing the proxied connection. For
ordinary HTTP requests this default is reasonable, but WebSocket
connections are long-lived: once established, they stay open for the
duration of the client session. When a job runs for more than 60 seconds
without sending any WebSocket frames (no progress updates, no interim
results), nginx interprets the silence as a stalled upstream and tears
down the proxy connection — dropping the WebSocket tunnel.

[AArch64] Remove dangling function declaration in AArch64PointerAuth (#185439)
Function `checkAuthenticatedLR` was declared but not defined anywhere.
This patch removes the dangling declaration.
[flang][NFC] Converted five tests from old lowering to new lowering (part 28) (#185549)
Tests converted from test/Lower/Intrinsics: dreal.f90, dshiftl.f90,
dshiftr.f90, eoshift.f90, erfc_scaled.f90
[LLVM][CodeGen][SVE] Implement isel for maximumnum/minimumnum. (#185074)
Patch to add custom lowering for FCANONICALIZE, FMAXNUM_IEEE, and
FMINNUM_IEEE, all of which are required when relying on default
expansion of FMAXIMUMNUM and FMINIMUMNUM.
The lowering is very simple because AArch64's FMAXNM and FMINNM
instructions are IEEE754-2008 compliant, with the implementation
effectively follow the same path take for NEON.
NOTE: Bfloat support will be provided separately.
[lldb][test] PlatformDarwinTest.cpp: add full error message to expected assertion
I'm about to reword the error message. Having test coverage for the
message will make that change easier to review/reason about.
[Clang] Restrict AMDGCN image built-ins (#180949)
Introduced validation for the `dmask` argument of the aforementioned
built-ins to match LLVM IR verifier behavior that is being changed in
llvm/llvm-project#179511.
[SystemZ] Add a SystemZ specific pre-RA scheduling strategy. (#135076)
This is a relatively simple strategy as it is omitting any heuristics for
liveness and register pressure reduction. This works well as the SystemZ ISel
scheduler is using Sched::RegPressure which gives a good input order to begin
with.
It is trying harder with biasing phys regs than GenericScheduler as it also
considers other instructions such as immediate loads directly into phys-regs
produced by the register coalescer. This can hopefully be refactored into
MachineScheduler.cpp.
It has a latency heuristic that is slightly different from the one in
GenericScheduler: It is activated for a specific type of region that have
many "data sequences" consisting of SUs connected only with a single
data-edge that are next to each other in the input order. This is only 3% of
all the scheduling regions, but when activated it is applied on all the
candidates (not just once per cycle). At the same time it is a bit more
careful by checking not only the SU Height against the scheduled latency but

[AMDGPU] Poison invalid globals after emitting error in LowerBufferFatPointers pass (#184662)
After the change from `report_fatal_error` to `Ctx.emitError` in #142014
there is a necessity to remove unsupported globals. Otherwise there is a
secondary crash during ISel when processing them

[TableGen] Do not order register classes based on heap addresses (#185644)
Compare registers using their enum values instead, which I suspect was
the intention in the first place, since we already have lexicographical
ordering defined for CodeGenRegisters.
This does not cause any changes in .inc files and is likely NFC, but
it's still best to have it be deterministic.
[libc] 185136 - added iswlower entry point (#185221)
Changes include:
- Added iswlower entrypoint in wctype.yaml to expose the function
- Created iswlower.h header and iswlower.cpp implementation
- Added CMake entrypoint object for iswlower
- Created unit test in iswlower_test.cpp
- Added test entry to wctype CMakeLists.txt
this PR helps in exposing iswlower which internally calls islower on
wide character
built using : ninja -C build libc
tested using : ninja libc_wctype_unittests and all the 3 tests passed
resolves issue #185136
