Hi!
I think it is better to merge ulps results rather than regenerate, that way
we don't suddenly start getting many errors when using slightly older
compilers.
Also, I think it is a bad idea to put
ldouble: 17987982955981951215498976719132
and similar into the libm-test-ulps file, only the ulps we want to tolerate
(< 10, < 12 or something like that).
2006-01-30 Jakub Jelinek <jakub@redhat.com>
* sysdeps/powerpc/fpu/libm-test-ulps: Merge ulps with older libm-test-ulps
rather than overwrite it. Remove excessively high ulps.
