[llvm-commits] [PATCH] Add X86 specific BUILD_VECTOR to SHUFFLE+INSERT_VEC_ELT transformation

[Michael Liao]

Hi

This patch obsoletes a previous patch adding the same functionality but
limited to X86 backend only. In general, this patch enables to build a
vector with SHUFFLE plus few INSERT_VECTOR_ELT to avoid the overhead to
BUILD_VECTOR entirely if possible.

Thanks for your review

Yours
- Michael
