[PATCH] D145893: [X86][MC]Fix wrong action for encode movdir64b

[Kan Shengchen via Phabricator via llvm-commits]

skan added a comment.

> Now llvm-mc can encode the asm 'movdir64b (%edx), rcx' but the result is the same as

I am confused about this statement.

1. What does the "Now" mean here? Before this patch or after this patch?
2. I can only see memory operand change in this patch, why it affects the register operand?
