--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For the original testcase.
Starting in GCC 4.8.0 we produce now:
movl $7, %ecx
leal -1(%edi), %eax
xorl %edi, %eax
sarl $15, %eax
subb ff_h264_norm_shift(%eax), %cl
sall %cl, %esi
Which is better and still one less register as you wanted.
So the original issue was fixed in GCC 4.8.
