Subject: Add more sNaN tests (cimag, conj, copysign, creal, fma, fmod)
	[committed]
Message-ID: <alpine.DEB.2.20.1606132126510.21659@digraph.polyomino.org.uk>
User-Agent: Alpine 2.20 (DEB 67 2015-01-07)
MIME-Version: 1.0

This patch adds tests of sNaN inputs to further libm functions.

Tested for x86_64 and x86.  Committed.

2016-06-13  Joseph Myers  <joseph@codesourcery.com>

	* math/libm-test.inc (cimag_test_data): Add sNaN tests.
	(conj_test_data): Likewise.
	(copysign_test_data): Likewise.
	(creal_test_data): Likewise.
	(fma_test_data): Likewise.
	(fmod_test_data): Likewise.
