glibc/sysdeps/i386/fpu
History
Joseph Myers 9bd3ef8e19 Fix i386/x86_64 expl, exp10l, expm1l for sNaN input (bug 20226). 
The i386 and x86_64 implementations of expl, exp10l and expm1l (code
shared between the functions) return sNaN for sNaN input.  This patch
fixes them to add NaN inputs to themselves so that qNaN is returned in
this case.

Tested for x86_64 and x86.

	[BZ #20226]
	* sysdeps/i386/fpu/e_expl.S (IEEE754_EXPL): Add NaN argument to
	itself.
	* sysdeps/x86_64/fpu/e_expl.S (IEEE754_EXPL): Likewise.
	* math/libm-test.inc (exp_test_data): Add sNaN tests.
	(exp10_test_data): Likewise.
	(expm1_test_data): Likewise.
