Eric Christopher	e6d6bfcc32	Don't lower splat vector load to relative to the esp if the ... stack may be misaligned. Update test accordingly. Patch by Evan Cheng! llvm-svn: 94291	2010-01-23 06:02:43 +00:00

Evan Cheng	9e2442c0be	Optimize splat of a scalar load into a shuffle of a vector load when it's legal. e.g. ... vector_shuffle (scalar_to_vector (i32 load (ptr + 4))), undef, <0, 0, 0, 0> => vector_shuffle (v4i32 load ptr), undef, <1, 1, 1, 1> iff ptr is 16-byte aligned (or can be made into 16-byte aligned). llvm-svn: 90984	2009-12-09 21:00:30 +00:00
