Bug ID: 115714
Summary: rs6000: Refine option -mabi={no-}altivec handlings
with some related option
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: linkw at gcc dot gnu.org
Target Milestone: ---
As Peter found in [1], even with altivec flag explicitly unset, we can still
have altivec_abi set, it's unexpected.
And we want to raise error when specify -mabi=no-altivec for linux 64 bit ABI
as Segher's comments in [2].
Besides, we need to sort out the combination between -mabi={no-}altivec and
-m{no-,}altivec (or -mvsx etc.) and raise warning/error if needed.
So filing this to track these.
