# Review report for pipeline/04b-pre-link-passes.md

## Summary

The pre-link mandatory-pass page is aligned with `generateIRForTranslationUnit` at the recorded source commit. I found no ordered-pass, gate, loop, or link issues.

## Items checked

- Ran `regenerate.py show pipeline/04b-pre-link-passes.md` and read the target page, `_common.md`, `pipeline-04b-pre-link-passes.md`, and dependencies `pipeline/03-semantic-check.md`, `pipeline/04-ast-to-ir.md`, `pipeline/05-ir-passes.md`, and `ir-reference/index.md`.
- Verified front matter keys, recorded source commit, and 64-character hex watched-path digest.
- Checked every line-number citation in the body against `source/slang/slang-lower-to-ir.cpp` and sampled linked pass implementation headers/files.
- Verified the ordered Phase A-D tables against `generateIRForTranslationUnit`, including `prelinkIR`, `lowerErrorHandling`, `lowerDefer`, `synthesizeBitFieldAccessors`, `lowerExpandType`, debug-value insertion, SSA/SCCP/CFG/peephole/DCE, loop inversion, early inlining, non-essential validation, stripping, obfuscation, validation, and mangled-name-map construction.
- Confirmed the pass-level loop description matches the `for (;;)` body and that the page does not mislabel pre-link calls as `SLANG_PASS` calls.
- Resolved relative links with `regenerate.py lint` for this assigned doc group; lint reported no issues.

## Findings

(no findings)

## No-issues notes

- The source line numbers reflect the current shifted locations around `generateIRForTranslationUnit`.
- The mandatory-early-inlining loop description correctly notes the overwritten `changed` value after `peepholeOptimizeGlobalScope`.
- The adjacent constructs section stays within the required three constructs.
