Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Ever confirmed|0 |1 Status|UNCONFIRMED |WAITING Last reconfirmed| |2025-05-26 --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- a0_in_asm() looks like invalid inline asm in the first place. It does not clobber r0. And a0_in_asm() has no return statement. Can you fix up the a0_in_asm function to have the correct code in thr first place and try again?
