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.
[CodeGen] Add target MIR text schema2026-08-03T11:24:30ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-03T11:24:30Zurn:sha1:432efe39315ed5ad0162f9c08dbf10941bc21dc1[CodeGen] Add target register descriptions2026-08-01T08:07:24ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-01T08:07:24Zurn:sha1:924dcd36ebed84f04729de05ec08b311a36a04c1
Introduce an immutable register topology for units, subregisters, classes, banks, and preserved masks. Bind instruction descriptors to this topology through TargetDescription so builders, cloning, and verification share one target-aware contract. Add the test-only TestTarget model and positive and negative target fact coverage.
[CodeGen] Add target state and compilation status2026-08-01T06:50:04ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-01T06:50:04Zurn:sha1:cfdbcc469f9691bd9dce3b0b86982a63d86ca6b7[CodeGen] Add constant and jump table state2026-08-01T06:19:20ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-01T06:19:20Zurn:sha1:a69d14b8ebc028dddc689658b08d42d3e83f5e38
Add stable, tombstone-preserving MachineConstantPool and MachineJumpTableInfo ownership. Define the versioned TargetConstant contract and integrate all table references with builders, verification, and deterministic deep cloning.
[CodeGen] Add MachineFrameInfo2026-08-01T05:55:21ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-01T05:55:21Zurn:sha1:c9634fa9f529afbdf622a9cd96741bd09d14ef86
Model stable frame indices, stack object kinds, tombstones, lifetimes, and frozen layouts. Validate owned frame references in the builder and verifier, and remap complete frame state during MachineFunction cloning.
