Bug ID: 112096 Summary: `(a || b) ? a : b` should be simplified to a Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: missed-optimization Severity: enhancement Priority: P3 Component: tree-optimization Assignee: unassigned at gcc dot gnu.org Reporter: pinskia at gcc dot gnu.org Target Milestone: --- Take: ``` int t0(int x, int y) { _Bool t = x == 0 && y == 0; if (t) return x; return y; } // y int t0_(int x, int y) { _Bool t = x == 0 && y == 0; if (t) return 0; return y; } // y int t1(int x, int y) { _Bool t = x || y; if (t) return x; return y; } // x int t1_(int x, int y) { _Bool t = x || y; if (t) return x; return 0; } // x ``` These should be simplified as the comment says All 4 of these are caught by LLVM.
