------- Additional Comments From jvdelisle at gcc dot gnu dot org 2008-03-30 00:09 -------
On a openSUSE 11.0alpha3, x86_64, glibc 2.7 (20071106 system, the sinf() calls
the ../sysdeps/x86_64/fpu/s_sincosf.c:175 FPU function whereas on a Fedora 8
system with glibc 2.7 the ../sysdeps/ieee754/flt-32/s_sinf.c, line 29 software
implementation of sinf is called.
Any suggestions on how to fix this. We should be using the FPU calls.
