Compiler and backend validation archive

These records describe specific regression investigations and the checks performed at those checkpoints. They are historical evidence, not a claim that every backend or full application has been retested at the current revision. Keep each report’s source state, device, limitations and local artifact references when interpreting its results.

For current Tile status and route comparisons, see the Tile report. The original report paths are retained so existing links remain valid.

Execution storage and coroutine runtime

• Shared-capacity auxiliary pipelines
• Materializable auxiliary storage and admission
• Local storage epochs and coroutine frame reconstruction
• Physical frame indices in selective-copy regression
• Exact queue handoff for pre-resume annotations
• Fallback barrier-coroutine allocation
• Fallback native-call temporary alignment
• Fallback queue predicate publication
• Packed coroutine words require a defined seed
• Logical continuation selection and opt-in resume batching
• Scope-specific executable coroutine transitions

Control-flow reconstruction

• Reconstruct disconnected owned conditional blocks
• Loop epochs before selection-merge inference
• Shared switch bodies across representation and CFG lowering
• Generated exit dispatches and loop-epoch convergence
• Preserve update payload when normalizing prepare backedges

Backend code generation

• SSA formation after late HIP callable inlining
• Metal world-shader code generation regressions
