[libc][math] Add iscanonical functions to math.yaml
Surface the existing iscanonical, iscanonicalbf16, iscanonicalf, iscanonicalf128, iscanonicalf16, and iscanonicall
implementations through the generated math.h.
To test:
`cmake -Bbuild -Sruntimes -GNinja -DLLVM_ENABLE_RUNTIMES=libc -DLLVM_LIBC_FULL_BUILD=ON`
`pip install pyyaml`
`ninja -C build libc.include.math.__generated_hdr__`
Then check `build/libc/include/math.h` for their signatures.
Add `-DLIBC_TYPES_HAS_FLOAT128=ON` to test for iscanonicalf128
in cmake invocation if host does not support it.
And `LIBC_TYPES_HAS_FLOAT16=ON` for iscanonicalf16.
[RISCV][TTI] Make getShuffleCost check we have a vector before querying getVectorElementCount (#199286)
Fixes the assert reported here:
<https://github.com/llvm/llvm-project/pull/198446#issuecomment-4522589671>
I believe this happens when the element type isn't a legal RVV element
type and so has been scalarised by type legalisation.
Adding this guard also matches the AArch64 implementation.
The test change is LLM generated.
[Clang][CodeGen] map `noescape` to capture(address) (was capture(none)) (#199281)
`capture(none)` has very restrictive semantics and an easy footgun to
accidentally fire some UB into your code with. Most significantly it
does not allow any visible side-effects of whether a pointer was null or
not to escape the function. This means that the function cannot perform
different side effects depending on whether a pointer marked `noescape`
is null. Relax this to `captures(address)`, which allows information
about the numerical address to escape the function, but no provenance
(i.e. nothing that could be dereferenced) may escape.
As discussed in
https://discourse.llvm.org/t/rfc-updating-the-semantics-of-the-noescape-attribute/90326.
[MLIR][XeGPU]Extend load_matrix/store_matrix to support 1D SLM access (#198652)
This PR extended xegpu.load_matrix and xegpu.store_matrix to support 1D
mem_desc for contiguous SLM access
- Added unit tests for 1D load/store (valid ops and invalid cases)
- Added integration test verifying both 1D (<4096xbf16>) and 2D
(<64x128xbf16>), correctly lower through the full WG→SG→WI→XeVM pipeline

[VPlan][test] Fix use-after-free in dumpRecipeInPlan/dumpRecipeUnnamedVPValuesInPlan tests (#199275)
https://github.com/llvm/llvm-project/pull/195891 exposed a
use-after-free in the tests: `BinaryOperator *AI` [*] is deleted prior
to VPlan's destructor, which expects all the operands to still be alive.
This patch fixes the test (suggested by a Florian in
https://github.com/llvm/llvm-project/pull/199252#pullrequestreview-4348337988),
by preemptively detaching AI from the VPlan.
[*] No AI was harmed or used during the creation of this patch.
[Instrumentor] Add Cast instruction instrumentation support
We now allow to have instrumentation opportunities for many instructions
(=opcodes) to bundle common classes together. Users can use filters on
the opcode, type-id, and size to statically select what they are
interested in.
fix: iconv: move NULL checks before pointer arithmetic in iconvctl()
strchr() result was used in pointer arithmetic and incremented before
being checked for NULL. Move the guards above the strlcpy() call.
tcplay/cryptdisks: Suppress GCC 15 false-positive -Wmaybe-uninitialized.
GCC 15 cannot see that mem is always initialized after the
malloc NULL check. Use a guarded diagnostic pragma to suppress
the warning only on GCC >= 15.
various: Fix -Wstringop-overread and -Wdangling-pointer warnings.
Fix sizeof(&sum) vs sizeof(sum) bug in adventure save/restore.
Fix strcmp() on non-NUL-terminated fgetln() buffer in libfetch.
Suppress false positives in libefivar and libnvmm.
