[BZ #3919]
* math/libm-test.inc (log_test): Test -Inf and NaN. (log10_test, log1p_test, log2_test): Test -Inf. * sysdeps/i386/fpu/e_log.S (__ieee754_log): Don't raise FE_INVALID when argument is qNaN. * sysdeps/i386/fpu/e_logl.S (__ieee754_logl): Likewise. * sysdeps/i386/fpu/e_logf.S (__ieee754_logf): Likewise. * sysdeps/x86_64/fpu/e_logl.S (__ieee754_logl): Likewise. * sysdeps/x86_64/fpu/e_log10l.S (__ieee754_log10l): Replace andb $1, %ah with testb $1, %ah, don't test for parity, instead testb $4, %ah and jump if non-zero. * sysdeps/x86_64/fpu/e_log2l.S (__ieee754_log2l): Likewise. * sysdeps/x86_64/fpu/s_log1pl.S (__log1pl): Likewise. 2007-03-15 Jakub Jelinek <jakub@redhat.com>
