Andy Wingo d08cc4f6e2 Allow string->utf8 to constant-fold ... * module/language/tree-il/primitives.scm (*interesting-primitive-names*): (*primitive-accessors*): Add string->utf8, utf8->string, and string-utf8-length. (primitive-module): New public function, moved here from (language tree-il compile-bytecode). * module/language/tree-il/compile-bytecode.scm: Use primitive-module from (language tree-il primitives). * module/language/tree-il/peval.scm (peval): A bugfix: load primitives from their proper module. Allows bytevector primitives to fold. * module/language/cps/guile-vm/reify-primitives.scm: * module/language/cps/effects-analysis.scm: * module/language/cps/types.scm * module/language/tree-il/primitives.scm: * module/language/tree-il/cps-primitives.scm: * module/language/tree-il/effects.scm (make-effects-analyzer): Add string->utf8, utf8->string, and string-utf8-length. * module/language/tree-il/compile-cps.scm (string->utf8) (string-utf8-length, utf8->string): New custom lowerers, including type checks and an unboxed result for string-utf8-length. * module/system/vm/assembler.scm: * libguile/intrinsics.h: * libguile/intrinsics.c: Because string-utf8-length returns an unboxed value, we need an intrinsic for it; go ahead and add an intrinsic for string->utf8 and utf8->string too, as we will likely be able to use these in the future.		2023-11-15 10:44:21 +01:00
