[PATCH] D32273: [X86][AVX512]

[Guy Blank via Phabricator via llvm-commits]

guyblank created this revision.

Following this RFC <https://groups.google.com/forum/#!msg/llvm-dev/-OmfyIY3SaU/n0ak_jyyBQAJ;context-place=forum/llvm-dev>.
This patch defines the i1 type as illegal in the X86 backend for AVX512.
for DAG operations on <N x i1> types (build vector, extract vector element, ...) i8 is used, and should be truncated/extended.
A v1i1 MVT is added to support scalar instruction that use masks, like floating point compare.
