Andy Wingo	53e28ed9b2	static opcodes; refactor program/objcode division; use new assembly pipeline * gdbinit: Untested attempts to get the stack fondling macros to deal with the new program representation. * libguile/frames.c (scm_vm_frame_arguments, scm_vm_frame_source) (scm_vm_frame_local_ref, scm_vm_frame_local_set_x): SCM_PROGRAM_DATA is a struct scm_objcode. libguile/instructions.h: * libguile/instructions.c: Hide the instruction table and the struct scm_instruction structure; all access to instructions now goes through procedures. This is because instructions are no longer in a packed array indexed by opcode. Also, declare a mask that all instructions should fit in. * libguile/objcodes.h: * libguile/objcodes.c: Rewrite so that object code directly maps its arity and length from its bytecode. This makes it unnecessary to keep this information in programs, allowing programs to be simple conses between the code (objcodes) and data (the object table and the closure variables). * libguile/programs.c (scm_make_program): Rework so that make-program takes objcode, an object table, and externals as arguments. It's much clearer this way, and we avoid malloc(). * libguile/stacks.c (is_vm_bootstrap_frame): Update for program/objcode changes. * libguile/vm-engine.c (vm_run): Initialize the jump table on the first run, with the opcodes declared in the instruction sources, and with bad instructions raising an error instead of wandering off into the Unknown. * libguile/vm-engine.h (FETCH_LENGTH): Always represent lengths as 3 bytes. The old code was too error-prone. (NEXT_JUMP): Mask the instruction with SCM_VM_INSTRUCTION_MASK. (NEW_FRAME): Update for program/objcode changes. * libguile/vm-expand.h (VM_DEFINE_FUNCTION, VM_DEFINE_INSTRUCTION) (VM_DEFINE_LOADER): Update so that we explicitly specify opcodes, so that we have a stable bytecode API. * libguile/vm-i-loader.c: Update license to LGPLv2+. Explicitly declare opcodes. (load-integer): Use an int instead of a long as the accumulator; still need to revisit this code at some point, I think. (load-program): Simplify, thankfully!! Just creates the objcode slice and rolls with it. * libguile/vm-i-scheme.c: Number the opcodes explicitly. * libguile/vm-i-system.c: Update license to LGPLv2+. Explicitly declare opcodes. (make-closure): Update for new program API. * libguile/vm.c (vm_make_boot_program): Update for new program/objcode API. Still a bit ugly. (scm_load_compiled_with_vm): Update for new program/objcode API. * module/language/assembly.scm (byte-length): Fix byte-length calculation for loaders, and load-program. (code-pack, code-unpack): Start to move things from (system vm conv) here. (object->code, code->object): More things from conv.scm. * module/language/glil.scm (<glil-program>): Add a new field, closure-level. (make-glil-program, compute-closure-level): Calculate the "closure level" when making a glil program. This is the maximum depth of external binding refs in this closure. (unparse-glil): Fix label serialization. * module/language/glil/compile-assembly.scm (make-meta): Prepend #f for the meta's object table, though maybe in the future we can avoid creating assembly in the first place. (assoc-ref-or-acons, object-index-and-alist): GRRR! Caught again by the different sets of arguments to assoc and assoc-ref! (glil->assembly): Attempt to make the <glil-program> case more readable, and fix the bugs. Sorry I don't know how to comment this change any more than this. (glil->assembly): For <glil-module> serialize the whole key, not just the name. (dump-object): subprogram-code is already a list. Serialize integers as strings, not u8vectors. Fix the order of lists and vectors. * module/language/glil/spec.scm (glil): Switch orders, so we prefer glil -> assembly -> objcode. Actually glil->objcode doesn't work any more, needs to be removed I think. * module/language/objcode/spec.scm (objcode->value): s/objcode->program/make-program/. * module/language/scheme/inline.scm: Add acons inline. * module/system/vm/conv.scm (make-byte-decoder): Skip the first 8 bytes, they are header. Handle subprograms properly. Still needs help though. (decode-length): Lengths are always 3 bytes now. * module/system/vm/disasm.scm: Superficial changes to keep things working. I'd like to fix this better in the future. * module/system/vm/frame.scm (bootstrap-frame?): Fixes for program-bytecode. * module/system/vm/program.scm: Export make-program. It's program-objcode now, no more program-bytecode. * module/system/vm/vm.scm (vm-load): Use make-program. * test-suite/tests/asm-to-bytecode.test: New test, very minimal. * module/system/vm/objcode.scm: Export word-size, byte-order, and write-objcode.	2009-01-29 21:12:00 +01:00
Andy Wingo	3de80ed52f	recompiling with compile environments, fluid languages, cleanups * ice-9/boot-9.scm (compile-time-environment): Remove definition from boot-9 -- instead, autoload it and `compile' from (system base compile). * libguile/objcodes.h: * libguile/objcodes.c (scm_objcode_to_program): Add an optional argument, `external', the external list to set on the returned program. * libguile/vm-i-system.c (externals): New instruction, returns the external list. Only used by (compile-time-environment). * libguile/vm.c (scm_load_compiled_with_vm): Adapt to scm_objcode_to_program change. * module/language/scheme/translate.scm (translate): Actually pay attention to the environment passed as an argument. (custom-transformer-table): Expand out (compile-time-environment) to something that can be passed to `compile'. * module/system/base/compile.scm (current-language): Instead of hard-coding `scheme' in various places, use a current language fluid, initialized to `scheme'. (compile-file, load-source-file): Adapt to current-language. (load-source-file): Ada (scheme-eval): Removed, no one used this. (compiled-file-name): Don't hard-code "scm" and "go"; instead use the %load-extensions and %load-compiled-extensions. (cenv-module, cenv-ghil-env, cenv-externals): Some accessors for compile-time environments. (compile-time-environment): Here we define (compile-time-environment) to something that will return #f; the compiler however produces different code as noted above. (compile): New function, compiles an expression into a thunk, then runs the thunk to get the value. Useful for procedures. The optional second argument can be either a module or a compile-time-environment; in the latter case, we can recompile even with lexical bindings. (compile-in): If the env specifies a module, set that module for the duration of the compilation. * module/system/base/syntax.scm (%compute-initargs): Fix a bug where the default value for a field would always replace a user-supplied value. Whoops. * module/system/il/ghil.scm (ghil-env-dereify): New function, takes the result of ghil-env-reify and turns it back into a GHIL environment. * scripts/compile (compile): Remove some of the tricky error handling, as the library procedures handle this for us. * test-suite/tests/compiler.test: Add a test for the dynamic compilation bits.	2008-10-30 10:57:36 +01:00

merge guile-vm into libguile itself

* ice-9/boot-9.scm: Only define load-compiled as #f if it's not already
  defined, which won't normally be the case.

* libguile/frames.c: (with change frame? -> heap-frame?)
* libguile/frames.h:
* libguile/instructions.c:
* libguile/instructions.h:
* libguile/objcodes.c:
* libguile/objcodes.h:
* libguile/programs.c:
* libguile/programs.h:

* libguile/vm-i-scheme.c: (was vm_scheme.c)
* libguile/vm-i-system.c: (was vm_system.c)
* libguile/vm.c:
* libguile/vm.h: These files moved here from src/, as guile-vm is now a
  part of libguile.

* libguile/init.c: Bootstrap the VM. Yay!

* libguile/Makefile.am: The necessary chicanery here.

* module/system/vm/Makefile.am:

* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm:

* pre-inst-guile-env.in: Add builddirs to the load path; add module/ to
  the path in the empty-$GUILE_LOAD_PATH case as well.

* src/Makefile.am: Moved out everything except guilec and guile-disasm,
  which probably should be moved to the scripts directory?

* testsuite/Makefile.am: Update to find guile-vm in the right place.

* module/system/vm/Makefile.am:
* module/system/vm/bootstrap.scm: Removed bootstrap.scm, scm_init_guile
  handles the bootstrapping for us.

* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
