[PATCH] D134477: [X86] Lower vector interleave into unpck and perm

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/test/CodeGen/X86/vector-interleave.ll:247
+; AVX2-NEXT:    vperm2f128 {{.*#+}} ymm0 = ymm1[0,1],ymm2[0,1]
+; AVX2-NEXT:    vperm2f128 {{.*#+}} ymm1 = ymm1[2,3],ymm2[2,3]
 ; AVX2-NEXT:    retq
----------------
Wouldn't AVX1 benefit from the v8f32 case as well?
