[PATCH] test/math: Adjust arm tests for older ULPs format

Gregory Fong gregory.0xf0 at gmail.com
Mon Apr 21 19:08:03 UTC 2014


The ULPs format in glibc has changed slightly and now deviates from
that in uClibc, so when using the files directly from glibc, for
certain types of tests the ULPs values were incorrectly defaulting to
0 rather than using the values provided.  This caused some tests to
fail despite the max ULPs being correctly marked.

Regenerated and updated part of the ULPs file to fix this issue.  This
also added values for exp and log.
