Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|unassigned at gcc dot gnu.org |jakub at gcc dot gnu.org Status|NEW |ASSIGNED --- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 54789 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54789&action=edit gcc13-pr91645.patch This seems to work right on the testcase I've been trying: float sqrtf (float); float foo (float x) { return sqrtf (x); } float bar (float x) { if (__builtin_isless (x, 0)) __builtin_unreachable (); return sqrtf (x); } float baz (float x) { if (!__builtin_isless (x, 0)) __builtin_unreachable (); return sqrtf (x); } float qux (float x) { x = x * x; return sqrtf (x); } Do we want this for GCC 13, or at least parts of it like the range-op-float.cc fixes and/or the value-range.cc change, or defer everything for GCC 14?
