commit 526af54142db14c1edcd2d80dc1b56d33ff4e8ce
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue May 19 23:05:22 2015 +0000
Fix i386 atanhl spurious underflows (bug 18049).
The i386 implementation of atanhl, for small arguments, does a
calculation that involves computing twice the square of the argument,
resulting in spurious underflows for some arguments. This patch fixes
this by just returning the argument when its exponent is below -32,
with underflow being forced as needed for subnormal arguments.
Tested for x86 and x86_64.
[BZ #18049]
* sysdeps/i386/fpu/e_atanhl.S (__ieee754_atanhl): For exponents
below -32, return the argument, with underflow if subnormal.
* math/auto-libm-test-in: Add more tests of atanh.
* math/auto-libm-test-out: Regenerated.
