[PATCH] x86emul: add missing EVEX.R' checks

2024-02-21 Thread Jan Beulich
EVEX.R' is not ignored in 64-bit code when encoding a GPR or mask register. While for mask registers suitable checks are in place (there also covering EVEX.R), they were missing for the few cases where in EVEX-encoded instructions ModR/M.reg encodes a GPR. While for VPEXTRW the bit is replaced befo
