avieira at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |avieira at gcc dot gnu.org --- Comment #2 from avieira at gcc dot gnu.org --- The last two should conflict though right? I never quite understood this warning to be fair. My personal preference would be to warn for any invocation where both -mcpu and -march are passed, but I understand that for legacy reasons that might be undesirable. Though yeah -mcpu=cortex-m55 with a -mfloat-abi=soft should not warn for anything obviously.
