Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Ever confirmed|0 |1 Status|UNCONFIRMED |NEW Last reconfirmed| |2025-02-11 --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note the original testcase no longer produces the trap; I have not looked into why. But a better testcase comes from https://github.com/llvm/llvm-project/pull/126807: ``` #define V int g(); void h(long long); void f() { long long a; int el2 = g(); if(el2) asm V ("mrs $0, SPSR_EL2": "=r"(a)); else asm V ("mrs $0, SPSR_EL3": "=r"(a)); h(a); } ``` Right now if V is defined to empty, ifcvt (ce1) pulls up one of the inline-asm to before the branch.
