--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alice Carlotti <[email protected]>: https://gcc.gnu.org/g:b41352c7aa2645de6c5751d447589c2ef8c4fa4d commit r17-3185-gb41352c7aa2645de6c5751d447589c2ef8c4fa4d Author: Alice Carlotti <[email protected]> Date: Fri Aug 7 17:56:49 2026 +0100 aarch64: Fix -march=native when -mtune is used [PR124629] Handling of -march=native for recognised cores was broken by r13-2937-g00c22ba69d8e73, which added "V" to ARCH_IDENT values and filtered it out in some locations. This causes a lookup by stringified ARCH_IDENT values to fail. If no -mtune or -mcpu option is used, then we avoid this bug by upgrading -march=native to -mcpu=native. Fix this by removing the '+ 1' string offset, so that the ident strings match again. It would be marginally more efficient to use enum values here, but I've stuck with this simpler fix instead. gcc/ChangeLog: PR target/124629 * config/aarch64/driver-aarch64.cc (AARCH64_ARCH): Don't skip first character of #ARCH_IDENT. gcc/testsuite/ChangeLog: PR target/124629 * gcc.target/aarch64/cpunative/info_36: New test file. * gcc.target/aarch64/cpunative/native_cpu_36.c: New test.
