Crate llvmkit_asmparser 

.ll (LLVM IR) lexer and parser.

The crate’s module layout mirrors the LLVM 22.1.4 AsmParser source tree (include/llvm/AsmParser/*.h + lib/AsmParser/*.cpp). One Rust file per C++ translation unit; header-only C++ files map to a Rust file of the same stem.

Rust module	LLVM source	Status
ll_lexer	LLLexer.h + LLLexer.cpp	done
ll_token	LLToken.h	done
file_loc	FileLoc.h	done
numbered_values	NumberedValues.h	done
slot_mapping	SlotMapping.h	done
asm_parser_context	AsmParserContext.h + .cpp	done
parse_error	LLParser.{h,cpp} diagnostic surface	seeded
ll_parser	LLParser.h + LLParser.cpp (subset)	seeded
parser	Parser.h + Parser.cpp	seeded

The substrate listed as done is the support layer the parser-first roadmap pulls in alongside LLParser; it ships before the parser core so Sessions 2-3 can wire their resolution / location pipelines against a stable interface (Roadmap section 10.5 forward-reference typestate).

Modules

asm_parser_context

Optional file-location registry produced by LLParser.

file_loc

Line / column source locations for parser diagnostics.

ll_lexer

.ll lexer — direct port of LLVM’s textual-IR lexer.

ll_parser

Textual .ll parser — module-level slice (Session 2).

ll_token

Token type and supporting enums for the .ll lexer.

module_summary

Module summary index parser and display support.

numbered_values

Slot-numbered value tables used by the textual IR parser.

parse_error

Typed parser-error catalogue.

parser

Public parser facade.

slot_mapping

Public parser-by-product table mapping slot numbers to IR handles.

Functions

read_to_owned

Drain r into a fresh Vec<u8>. Convenience helper for the common case where a caller has any Read source and wants to feed it to ll_lexer::Lexer::new.
