This series backports Arrow Lake and Arrow Lake-S x86 enablement from GCC 14 to
GCC 13 release branch code.
Changes in v2:
- Drop non-upstream helper artifacts under contrib/:
- contrib/arrowlake-backport-gap-report.md
- contrib/verify-arrowlake-backport.sh
- Keep the functional backport/tests/doc updates unchanged.
Scope:
- Add -march/-mtune Arrow Lake and Arrow Lake-S CPU handling.
- Backport AVXVNNIINT16, SM3, SM4 and SHA512 i386 backend/intrinsic support.
- Add missing invoke.texi option index/documentation entries.
- Fix SM3 immediate-argument compatibility in umbrella tests.
Testing:
- Targeted i386 tests for arrowlake/arrowlake-s feature and intrinsic coverage
pass with the same GCC 13 build tree used during validation.
Notes:
- All commits are DCO-signed.
- I do not have GCC write access; if this series is approved, please help
commit.
