Hello,
Patch in the bottom fixes iterator for k<logic> insns
since QI mode is only available for AVX-512DQ.
It also adds support for kshift[rl][bwdq]. This patterns
will be used for mask load/store autogeneration on which
Ilya Enkovich is working on.
gcc/
* config/i386/i386.md (define_code_attr mshift): New.
(define_mode_iterator SWI1248_AVX512BW): Rename ...
(SWI1248_AVX512BW): ... to this. Make QI enabled for TARGET_AVX512DQ
only.
(define_insn "*k<logic><mode>"): Use new iterator name.
(define_insn "*<mshift><mode>3"): New.
Bootstrapped and regtest in progress
Is it ok for trunk (if regtest pass)?

Thanks, K
