[ms] [llvm-ml] Standardize blocking of lexical substitution

Authored by epastor on Jun 13 2021, 8:19 AM.



In MASM, the ifdef family of directives treats its argument literally, without expanding it as a text macro. Add support for this, and also replace the special handling that was previously used for echo.

Nice! lg with clang-tidy addressed.


nit: Consider instead:

enum ExpandKind { ExpandMacros, DoNotExpandMacros };
const AsmToken &Lex(ExpandKind);

Then the call sites are much easier to read. (Also something similar for the other method below taking a bool below)


Why is this a pointer? You never set it to anything else and it can't be null -- make it a reference?


no else after return…oh, clang-tidy already said that. Do what clang-tidy says :) (also above)
