[PATCH] D74344: [ms] [llvm-ml] Add a draft MASM parser

[Eric Astor via Phabricator via llvm-commits]

epastor created this revision.
Herald added subscribers: llvm-commits, aheejin, hiraditya, mgorny.
Herald added a project: LLVM.

Many directives are unavailable, and support for others may be limited.

This first draft has preliminary support for:

- conditional directives (including errors),
- data allocation (unsigned types up to 8 bytes, and ALIGN),
- equates/variables (numeric and text),
- and procedure directives (without parameters),

as well as COMMENT, ECHO, INCLUDE, INCLUDELIB, PUBLIC, and EXTERN. Text variables (aka text macros) are expanded in-place wherever the identifier occurs.

We deliberately ignore all ml.exe processor directives.

Prominent features not yet supported:

- structs
- macros (both procedures and functions)
- procedures (with specified parameters)
- substitution & expansion operators
