Hello!
y->r and r->y interunit alternatives were missing for 64bit targets
for true MMX moves. These alternatives are present in a movdi pattern.
2013-03-24 Uros Bizjak <ubiz...@gmail.com>
* config/i386/mmx.md (mov<mode>): Add ?!Ym,r and r,?!Ym alternatives.
Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN.
Uros.
