--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-04-14 08:22:06 UTC ---
I confirm I can see this problem in RHEL6 libm, on the other side I can't
reproduce with git trunk glibc, even if I compile e_rem_pio2f.c with GCC
4.4-RH, 4.6 or GCC trunk.
.LVL0:
        pushq   %rbp
.LCFI0:
        .cfi_def_cfa_offset 16
        .cfi_offset 6, -16
.LBB2:
        .loc 1 113 0
#APP
# 113 "../sysdeps/ieee754/flt-32/e_rem_pio2f.c" 1
        movd %xmm0, %ebp
is correct.
