Stage 1 Task 1. analyzer.clj punted set literals to the interpreter
((form-set? form) (uncompilable "set literal")); now it builds the set-node IR
(already defined in ir.clj) from (form-set-items form), and backend.janet emits
(make-phs e1 e2 …) — each element evaluated then the persistent set built,
mirroring compiler.janet's emit-set-expr and the interpreter's :jolt/set path.
Closes a self-hosted-analyzer vs bootstrap-compiler parity gap: #{…} no longer
forces interpreter fallback on the compile path.
Gate: conformance 262x3 (+4 set-literal cases incl computed elements / empty /
in-let), fixpoint, self-host, sci, suite 3981/66, specs+unit green; core-bench
neutral (A/B). set?/disj-as-fns remain deliberately interpreted (in-sync across
all three lists) — adjudicated in Task 2.
adds self-hosted compiler is functionally:
- The default compile path is the portable pipeline using jolt.analyzer (Clojure) → host-neutral IR → backend.janet.
- The analyzer is itself Clojure, compiled by jolt for true self-hosting.
- bootstrap-fixpoint passes (stage1 == stage2 == stage3): rebuilding the compiler on its own output.
- clojure.core is now self-hosted in the overlay.
- Stateful forms (defmacro/ns/deftype/defmulti/require/in-ns) are interpreted by design.
