https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68356 --- Comment #15 from Iain Sandoe --- by coincidence (triaging Darwin bugs at the moment) I was looking at this last night. An alternative, for platforms with math_errhandling and which use MATH_ERREXCEPT, (Darwin and a couple of others) could be to arrange for the tests to check the exception conditions when MATH_ERREXCEPT is set in math_errhandling and errno otherwise (I was thinking of looking into adding an extra field to the TEST macro for the exception bit value). However, if there's not 1:1 mapping (it could be that the exception bits are more fine-grained), then perhaps better to skip the test and add a similar one that is keyed off the exception bits instead.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68356 --- Comment #14 from joseph at codesourcery dot com --- I'd expect any complete patch default to -fno-math-errno to add -fmath-errno to all tests relating to errno setting by libm functions (so that patch was incomplete for lack of test updates). Those tests, independently, should be disabled on platforms which do not support errno setting in libm.

There has been discussion on making ALL platforms default to -fno-math-errno lately on gcc-patches: https://gcc.gnu.org/ml/gcc-patches/2018-01/msg01065.html I assume if that were to happen, it'd make sense just to remove the test entirely?

The other tests pass okay, so I think I'll do the same skip as __sun__ around exp2 and expm1 even though I think expm1 would pass since it supports ERANGE errors.

Yes, or at least what's testing errno in it (which looks like pretty much the whole test). Or, better, add an effective-target keyword for math-errno support and restrict the test based on that (and convert any present skips of math-errno tests for Darwin to use the new effective-target keyword) - it's not the only system without math-errno support in its libm.
