rcc-project/backend/include/rcc/CodeGen/MachineMetadata.h, branch master An optimizing compiler for C. https://git.richardqin.org/rcc-project/atom?h=master 2026-08-06T17:27:41Z [MIR] Complete document parsing and printing 2026-08-06T17:27:41Z Richard-Qin-X richard.qin.001@gmail.com 2026-08-06T17:27:41Z urn:sha1:76d89700953ddd81cf31ab8f260eddf67e93aa85 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. [CodeGen] Model machine debug metadata 2026-08-01T19:37:46Z Richard-Qin-X richard.qin.001@gmail.com 2026-08-01T19:37:46Z urn:sha1:a8a9d7d926202450645deae872d4d9dc11d63215 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 graphs 2026-08-01T18:56:39Z Richard-Qin-X richard.qin.001@gmail.com 2026-08-01T18:56:39Z urn: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.
