Hello,
This series adds support for the priority syntax in aarch64 version strings.
This series makes a small change to the same_function_version hook in order
to support priority syntax, and requires updating the callers to that function.
Changes for V4:
- Addressed Wilco's feedback on logic in disjoint_version_decls.
- Pushed approved patches
Changes for V3:
- Addressed Wilco's feedback on logic in aarch64_parse_fmv_features.
- Fixed grammar in commit message.
Changes for V2:
- Added tests for priority version errors.
- Changed disjoint_version_decls to have an explicit new_decl and old_decl
- Change a call to disjoint_version_decls in c frontend where they were the
wrong way around.
- Simplified and corrected some of my parsing logic as Wilco suggested.
- Changed how the aarch64 version order test works as discussed with Wilco.
- Adds patch to add FMV support macro
Regr tested on aarch64-linux-gnu and x86-linux-gnu.
Ok for master?
Thanks.
Alfie
