* module/system/base/language.scm (<language>): Rework so that instead of hardcoding passes in the language, we define compilers that translate from one language to another. Add `parser' to the language fields, a bit of a hack but useful for languages with s-expression external representations but with record internal representations. (define-language, *compilation-cache*, invalidate-compilation-cache!) (compute-compilation-order, lookup-compilation-order): Add an algorithm that does a depth-first search for a translation path from a source language to a target language, caching the result in a lookup table. * module/language/scheme/spec.scm: * module/language/ghil/spec.scm: Update to the new language format. * module/language/glil/spec.scm: Add a language specification for GLIL, with a compiler to objcode. Also there are parsers and printers, for repl usage, but for some reason this doesn't work yet. * module/language/objcode/spec.scm: Define a language specification for object code. There is some sleight of hand here, in the "compiler" to values; but there is method behind the madness, because this way we higher levels can pass environments (a module + externals pair) to objcode->program. * module/language/value/spec.scm: Define a language specification for values. There is something intellectually dishonest about this, but it does serve its purpose as a foundation for the language hierarchy. * configure.in: * module/language/Makefile.am * module/language/ghil/Makefile.am * module/language/glil/Makefile.am * module/language/objcode/Makefile.am * module/language/value/Makefile.am: Autotomfoolery for the ghil, glil, objcode, and value languages. * module/language/scheme/translate.scm (translate): Import the bits that understand `compile-time-environment' here, and pass on the relevant portions of the environment to the next compiler pass. * module/system/base/compile.scm (current-language): New procedure, refs the current language fluid, or lazily sets it to scheme. (call-once, call-with-output-file/atomic): Refactor these bits to use with-throw-handler. No functional change. (compile-file, compile-and-load, compile-passes, compile-fold) (compile): Refactor the public interface of the compiler to be generic and simple. Uses `lookup-compilation-order' to find a path from the source language to the target language. * module/system/base/syntax.scm (define-type): Adapt to changes in define-record. (define-record): Instead of expecting all slots in the first form, expect them in the body, and let the first form hold the options. * module/system/il/compile.scm (compile): Adapt to the compilation pass API (three in and two out). * module/system/il/ghil.scm (<ghil-var>, <ghil-env>) (<ghil-toplevel-env>): Adapt to define-record changes. * module/system/il/glil.scm (<glil-vars>): Adapt to define-record changes. (<glil>, print-glil): Add a GLIL record printer that uses unparse. (parse-glil, unparse-glil): Update unparse (formerly known as pprint), and write a parse function. * module/system/repl/common.scm (<repl>): Adapt to define-record changes. (repl-parse): New function, parses the read form using the current language. Something of a hack. (repl-compile): Adapt to changes in `compile'. (repl-eval): Fix up the does-the-language-have-a-compiler check for changes in <language>. * module/system/repl/repl.scm (start-repl): Parse the form before eval. * module/system/repl/command.scm (describe): Parse. (compile): Be more generic. (compile-file): Adapt to changes in compile-file. (disassemble, time, profile, trace): Parse. * module/system/vm/debug.scm: * module/system/vm/assemble.scm: Adapt to define-record changes. * module/language/scheme/translate.scm (receive): Fix an important bug that gave `receive' letrec semantics instead of let semantics. Whoops!
