Vincent Lefèvre <vincent-gcc at vinc17 dot net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |vincent-gcc at vinc17 dot net --- Comment #5 from Vincent Lefèvre <vincent-gcc at vinc17 dot net> --- The -frounding-math option should solve the issue on this particular example. But on my machine, ld gives an "undefined reference to `_up'" error. For a more general bug, see PR34678.
