← Language Reference | IR Reference | Target Reference
All Trident compiler diagnostics — errors, warnings, and optimization hints. Derived from the language specification (language.md), target constraints (targets.md), and IR tier rules (ir.md).
This catalog is the source of truth for diagnostics. If a rule in the reference can be violated, the error must exist here. Entries marked (planned) are specification-required but not yet implemented in the compiler.
The catalog is derived systematically from the specification, not reverse-engineered from compiler source. Every violable rule produces at least one diagnostic entry.
-
Extract — Scan language.md, targets.md, and ir.md for prohibition keywords: "must", "cannot", "only", "requires", "forbidden", "not supported", "rejected", "maximum", "minimum".
-
Classify — Is the constraint user-violable? Internal compiler invariants don't need user-facing errors. Only rules that a programmer could break in source code qualify.
-
Map — Each violable constraint maps to at least one catalog entry. Some constraints produce multiple errors (e.g., "no subtraction" catches
-,--,-=). -
Audit — Gaps cluster in predictable categories:
- Excluded-feature diagnostics (every Rust/C keyword users try)
- Tier-gating for compound features (seal uses sponge internally)
- Semantic domain errors (inv(0), hash rate mismatches)
- Attribute argument validation
-
Maintain — When adding a language feature, add its violation modes to the catalog simultaneously. The spec change and the error entry ship together.
165 diagnostics cover every user-violable "must"/"cannot"/"only" constraint in the language reference (language.md, grammar.md), targets.md, and ir.md. The derivation was audited by scanning all reference documents for prohibition keywords and cross-referencing each against the catalog.
