* module/language/cps/compile-bytecode.scm (compile-function): Expect eq-constant? instead of eq-null?, etc. * module/language/cps/effects-analysis.scm: Likewise. * module/language/cps/reify-primitives.scm (reify-primitives): For eq-constant?, reify a $const unless the constant is an immediate whose encoding fits in 16 bits. * module/language/cps/type-fold.scm (materialize-constant): Helper to make a constant from a type, min, and max. (fold-eq-constant?): New helper. (eq-constant?): New folder. (undefined?): Define specifically. (define-nullish-predicate-folder): Renamd from define-special-immediate-predicate-folder. Use only for null?, false, and nil?. (*branch-reducers*): New mechanism. Reduce eq? to eq-constant? if possible. (local-type-fold): Refactor to use materialize-constant, and to allow reducing branches. * module/language/cps/types.scm (constant-type): Return three values instead of a type entry. (constant-type-entry): New function that returns a type entry. Adapt callers. (infer-constant-comparison): New helper. (eq-constant?): New inferrer. (undefined?): New inferrer. * module/language/tree-il/compile-bytecode.scm (eq-constant?): Fix truncate-bits signed arg. (define-immediate-type-predicate): Adapt to visit-immediate-tags change. * module/language/tree-il/compile-cps.scm (convert): Convert eq? to constant to eq-constant?. Advantaged is that it gets fixnums and chars in addition to special immediates. * module/language/tree-il/cps-primitives.scm (define-immediate-type-predicate): Adapt to allow #f as pred. * module/system/base/types/internal.scm (immediate-tags): Use #f as pred for false, nil, etc. (immediate-bits->scm): Adapt. * module/system/vm/assembler.scm (emit-eq-null?, emit-eq-nil?) (emit-eq-false?, emit-eq-true?, emit-unspecified?, emit-eof-object?): Remove specialized emitters. * module/system/vm/assembler.scm (define-immediate-tag=?-macro-assembler): Allow for pred to be #f. * module/system/vm/disassembler.scm (define-immediate-tag-annotation): Adapt to pred being #f. |
