--- Comment #23 from Jan Kratochvil <jkratochvil at azul dot com> --- Created attachment 54542 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54542&action=edit fmoderrno.cpp (In reply to Uroš Bizjak from comment #21) > When g:93ba85fdd253b4b9cf2b9e54e8e5969b1a3db098 is reverted, current > mainline does not emit anything that would handle errno (even with > -fmath-errno flag explicitly set at command line). With 4341106354c6a463ce3628a4ef9c1a1d37193b59 (=2023-02-25), 93ba85fdd253b4b9cf2b9e54e8e5969b1a3db098 reverted and fmoderrno.cpp I get: fmod(1.0D, 0.0D) g++ -o fmoderrno fmoderrno.C -O3 -Wall; ./fmoderrno -nan errno=33=Numerical argument out of domain
