Subject: [PATCH] i386: Add ssemov2, sseicvt2 for some load instructions that
use memory on operand2
The memory attr of some instructions should be 'load', but these are
'none', currently.
gcc/ChangeLog:
* config/i386/i386.md: Add ssemov2, sseicvt2.
* config/i386/sse.md (sse2_cvtsi2sd): Apply sseicvt2.
(sse2_cvtsi2sdq<round_name>): Ditto.
(vec_set<mode>_0): Apply ssemov2 for 4, 6.
