<pre>
    I have a few questions for you good folks.

1、How to use "MCAsmParser" to parse Microsoft style inline assembly, the current llvm syntax [mov %eax, %eax] and Microsoft style syntax [mov eax, eax], if I use Microsoft inline assembly syntax, llvm will report an error [error: unknown use of instruction mnemonic without a size suffix
mov eax, eax]
2、Is there any relevant setting, any idea to add relevant setting in "MCAsmLexer"?
3、Can I modify the lexical analysis in the source code to remove the % prefix, which files should I modify, or key files?
