This commit add an initial support for a better type propagation and integer range propagation. Each mvar can be now characterized by a set of types, a set of values and an integral range. * lisp/emacs-lisp/comp.el (comp-known-ret-types): Store into typeset and remove fixnum. (comp-known-ret-ranges, comp-type-predicates): New variables. (comp-ctxt): Remove supertype-memoize slot and add union-typesets-mem. (comp-mvar): Remove const-vld, constant, type slots. Add typeset, valset, range slots. (comp-mvar-value-vld-p, comp-mvar-value, comp-mvar-fixnum-p) (comp-mvar-symbol-p, comp-mvar-cons-p) (comp-mvar-type-hint-match-p, comp-func-ret-typeset) (comp-func-ret-range): New functions. (make-comp-mvar, make-comp-ssa-mvar): Update logic. (comp--typeof-types): New variable. (comp-supertypes, comp-common-supertype): Logic update. (comp-subtype-p, comp-union-typesets, comp-range-1+) (comp-range-1-, comp-range-<, comp-range-union) (comp-range-intersection): New functions. (comp-fwprop-prologue, comp-mvar-propagate) (comp-function-foldable-p, comp-function-call-maybe-fold) (comp-fwprop-insn, comp-call-optim-func, comp-finalize-relocs): Logic update. * src/comp.c (emit_mvar_rval, emit_call_with_type_hint) (emit_call2_with_type_hint): Logic update. * lisp/emacs-lisp/cl-preloaded.el (cl--typeof-types): Undo the add of fixnum and bignum as unnecessary. * test/src/comp-tests.el (comp-tests-mentioned-p-1, comp-tests-cond-rw-checker-val) (comp-tests-cond-rw-checker-type, cond-rw-1, cond-rw-2) (cond-rw-3, cond-rw-4, cond-rw-5): Update for new type interface. (range-simple-union, range-simple-intersection): New integer range tests. (union-types): New union type test. |
