--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
From the trunk I get (on aarch64):
_Z6mirrorRff:
.LFB0:
.cfi_startproc
ldr s2, [x0]
fmov s1, 2.0e+0
fnmsub s0, s0, s1, s2
str s0, [x0]
ret
_Z7mirror2Rff:
.LFB1:
.cfi_startproc
ldr s2, [x0]
fmov s1, 2.0e+0
fnmsub s0, s0, s1, s2
str s0, [x0]
ret
I am not seeing any difference after the patch that fixed bug 63586 so closing
as a dup again.
