--- Comment #15 from Andreas Tobler <andreast at gcc dot gnu.org> --- Regarding comment #10, Steve is right with his guess, configure doesn't find the fenv functionalities needed. The reason is pretty simple, for aarch64 and powerpc, they are not public. A quick trial showed that if they are visible, then gfortran is 'happy' and nearly all ieee testcases pass. I did not investigate the failing parts. The big issue is, how can we make them available to libm. This is an OS issue and not a gcc issue. The only thing I'm confused in gcc land, as Steve as well, why is the file named fpu-glibc and not fpu-fenv? Regarding the OS issue, it might take a while to (re)solve this.
