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.
[CodeGen] Add machine function records2026-08-01T09:58:12ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-01T09:58:12Zurn:sha1:6e09614afd2a589690d107b41308f6fe6614c266
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.
[CodeGen] Add MIR function and block attributes2026-08-01T09:36:40ZRichard-Qin-Xrichard.qin.001@gmail.com2026-08-01T09:36:40Zurn:sha1:787f3a7a20958bfa6f231abccc617f4d8de25c4d[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.
