- Subject: Add more tests of acosh, atanh, cos, csqrt, erfc, sin, sincos [committed]
- Authentication-results: sourceware.org; auth=none
This patch adds more randomly-generated tests of various libm
functions that are observed to increase ulps on x86_64.
Tested for x86_64 and x86 and ulps updated accordingly. Committed.
(auto-libm-test-out diffs omitted below.)

* math/auto-libm-test-in: Add more tests of acosh, atanh, cos,
csqrt, erfc, sin and sincos.
* math/auto-libm-test-out: Regenerated.
* sysdeps/i386/fpu/libm-test-ulps: Update.
