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] 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.
