Some checks are pending
docs / build-and-deploy (push) Waiting to run
Add `long`, a 64-bit signed integer primitive (i64), threaded through codegen: llty; int<->long coercion (coerce_code/to_long) at let/assign/ return/call-args; i64 arithmetic + comparison promotion in emit_bin; unary negate/~; print via %lld and str()/interpolation via @fn_long_str. Editor vocabulary (syntax header, TextMate grammar, formatter, LSP) synced; check-vocabulary green. Numeric literals stay i32 — build large values by widening (documented on the type page). Complete the Hash.* namespace (issue #17) with both 32- and 64-bit algorithms: Hash.of/fnv1a/crc32/mix/combine (32-bit) and Hash.of64/fnv1a_64/mix64 (64-bit, returning long). Deterministic and C-free; CRC-32 (poly 0xEDB88320) and FNV vectors verified against reference implementations. Tests: selfhost/tests/{hash,long}.ludic. Docs: docs/language/hash/*, type-long.md. Seed reseeded; C-free bootstrap fixpoint holds; 23 selfhost + 45 regression + 29 tooling checks green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
