Hello!
movd to/from MMX or SSE registers is SSE2 instruction. Also, remove
wrong x,x alternative.
2012-06-14 Uros Bizjak <[email protected]>
* config/i386/i386.md (*zero_extendsidi2): Mark movd alternatives
SSE2 only. Remove x,x alternative.
(*zero_extendsidi2_rex64): Ditto.
Bootstrapped and regression tested on x86_64-pc-linux-gnu, committed
to mainline SVN. Patch will be backported to other release branches.
Uros.
