Bug ID: 123460
Summary: aarch64: configure --with-arch incorrectly rejects
extension names containing hyphens
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: acarlotti at gcc dot gnu.org
Target Milestone: ---
The code in config.gcc to check the validity of an aarch64 --with-{arch|cpu}
extension string uses `sed -E -e 's/[a-z0-9]+//'` to remove an initial
extension name from the string before parsing the remaining extensions. This
fails for extensions containing a "-" character, which were first added in
r10-593-g28108a53416535.
