Subject: Add more libm tests (fabs, fdim, fma, fmax, fmin, fmod) [committed]
Message-ID: <alpine.DEB.2.10.1510162253110.6532@digraph.polyomino.org.uk>
User-Agent: Alpine 2.10 (DEB 1266 2009-07-14)
MIME-Version: 1.0

This patch improves the libm test coverage for a few more functions.

Tested for x86_64 and x86.  Committed.

2015-10-16  Joseph Myers  <joseph@codesourcery.com>

	* math/libm-test.inc (fabs_test_data): Add more tests.
	(fdim_test_data): Likewise.
	(fma_test_data): Likewise.
	(fmax_test_data): Likewise.
	(fmin_test_data): Likewise.
	(fmod_test_data): Likewise.
