[PATCH] D151863: [x86][MC] Fix movdir64b addressing

[Akshay Khadse via Phabricator via llvm-commits]

akshaykhadse added a comment.

I am working on adding a proper test for this issue, but wanted to get a discussion started as I don't believe this is a proper fix. The reason why `if (getMemBaseReg() == X86::AH)` works is that an operand like`ZMMWORD PTR [RAX]` has `Memory: ModeSize=64,Size=512,BaseReg=ah,Scale=1,Disp=arr` i.e. the base reg is `ah`. Please guide me to indentify such operands when inside the `isMem512_GR64()` function.
