2020-08-30 Uros Bizjak <ubizjak@gmail.com>
gcc/ChangeLog:
PR target/96744
* config/i386/i386-expand.c (split_double_mode): Also handle
E_P2HImode and E_P2QImode.
* config/i386/sse.md (MASK_DWI): New define_mode_iterator.
(mov<mode>): New expander for P2HI,P2QI.
(*mov<mode>_internal): New define_insn_and_split to split
movement of P2QI/P2HI to 2 movqi/movhi patterns after reload.
gcc/testsuite/ChangeLog:
* gcc.target/i386/double_mask_reg-1.c: New test.
