Does -ffloat-store help on ppc64 though? I believe that target doesn't have
excess precision... Perhaps fma is used somewhere (can you objdump -dr
check_value.exe | grep madd ?)? No idea if it is possible

On big-endian ppc64 ext/special_functions/hyperg/check_value.cc these tests
fail:
data167, toler167 on line 11579 max_abs_frac = 4.82864e-13
data171, toler171 on line 11579 max_abs_frac = 5.15741e-12

On i686-linux, it is clearly a matter of excess precision that sometimes
substantially changes the result. With -mfpmath=sse -msse2 or -ffloat-store it
passes.
The abs errors for various tests that fail are

It's arguable whether this should be marked as a regression, as it's new code
and new tests, so the tests wouldn't even compile before gcc6.

FAIL: ext/special_functions/hyperg/check_value.cc execution test
seen also on i686-linux (dunno about x86_64, that is still doing make check).

--- Comment #3 from Jonathan Wakely ---
Apparently ext/special_functions/hyperg/check_value.cc is also failing on i686.
