Hi,
Silvermont processors have penalty for instructions having 4+ bytes of prefixes
(including escape bytes in opcode). This situation happens when REX prefix is
used in SSE4 instructions. This patch tries to avoid such situation by
preferring xmm0-xmm7 usage over xmm8-xmm15 in those instructions. I achieved
it by adding new tuning flag and new alternatives affected by tuning.
SSE4 instructions are not very widely used by GCC but I see some significant
gains caused by this patch (tested on Avoton on -O3).
DENmark (EEMBC2.0) +2%
TCPmark (EEMBC2.0) +32%
SPEC2000 +0,5%
Bootstrapped and tested on linux-x86_64.
Does it look OK for trunk?
Thanks,
Ilya
