Implement the single LLVM-compatible MIR document path with structured\nembedded-IR references, YAML mappings, constants, and deterministic printing.\n\nKeep pointer LLT widths DataLayout-derived, reject layout-dependent output\nwhen embedded IR is omitted, and record the fixed-baseline compatibility\ncontract and regression coverage.
[MIR] Add machine instruction parser and printer2026-08-03T21:34:15ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-03T21:34:15Zurn:sha1:183e2354e9fdd107be420cbb185c1d239434aa48
Parse MachineFunction bodies in two passes and serialize the same MachineIR model in complete or readable form. Extend instruction attachments and memory operands required by the fixed LLVM MIR grammar, and cover deterministic parse-print round trips.

Replace marker-based metadata operands with scoped references and inline DIExpression values. Add structured DILocation chains, instruction debug attachments, stack variable records, and entry values with unified verification, builder support, and deterministic cloning.
[CodeGen] Add machine metadata graphs2026-08-01T18:56:39ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-01T18:56:39Zurn:sha1:49d70380a6a95e4039f6b5e5ccce09671d5b4796
Model ordered function-local metadata tuples with explicit embedded-IR and MachineFunction reference scopes. Preserve slot zero, distinct nodes, forward references, and cyclic graphs while verifying function-local closure and cloning the graph deterministically.
[CodeGen] Track debug instruction identities2026-08-01T10:17:33ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-01T10:17:33Zurn:sha1:e0c77d80585428818c32886eb8c26755ea8ed159
Add monotonic MIR debug instruction numbers and structured value substitutions. Verify live number uniqueness, meta-instruction exclusion, substitution graph integrity, and target subregister references while preserving debug identities during cloning.
