| | | | Add an RCC-owned build-time target description generator and the initial RV64GC register model. Keep ABI aliases separate from canonical MIR register spelling.
* [MIR] Complete document parsing and printingRichard-Qin-X2026-08-0745-218/+11465
| | | | 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 printerRichard-Qin-X2026-08-0415-19/+5394
| | | | 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.

* [CodeGen] Add machine metadata graphsRichard-Qin-X2026-08-028-0/+492
| | | | 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 identitiesRichard-Qin-X2026-08-0110-0/+471
| | | | 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.

| | | | Represent callee-saved registers, call-site information, called globals, and prefetch targets in the core MachineIR model. Verify target and instruction references and remap StableIDs during explicit function cloning.
