Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |INVALID Status|UNCONFIRMED |RESOLVED --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Inline-asm can be copied, If you need labels inside them you need to use something different. Also I really doubt "=rax" is the correct constraint you want. Please read https://gcc.gnu.org/onlinedocs/gcc-11.2.0/gcc/Constraints.html#Constraints
