TileLang Error Fixer (npuir)

Mandatory routing rule

Before answering, follow AGENTS.md section "Docs Auto Routing Rules (Mandatory)".

Scope

• compile errors in npuir path
• runtime failures and invalid results
• pass pipeline divergence
• performance regressions

Diagnosis workflow

1. Confirm environment and target setting
2. Reproduce with smallest kernel
3. Classify issue type: compile, runtime, pass, precision, performance
4. Capture evidence: logs, IR snapshot, failing stage
5. Propose minimal patch and validate

NPUIR-specific checks

• verify default vector API style uses v-prefix ops
• verify alias callsites are semantically equivalent
• verify load_nd2nz and store_fixpipe size/layout consistency
• verify sync_block_set and sync_block_wait pairing

Official docs to consult

• docs/Tilelang算子调试指南.md
• docs/开发指南.md
• docs/developer/EnvironmentVariables.md
• docs/Tilelang.language/内存操作/T.load_nd2nz.md
