This reorganization kills the ugly module-export-all hacks in bootstrap.scm and core.scm. In fact, it gets rid of core.scm entirely, breaking out its functionality into separate files. * module/system/vm/trace.scm: * module/system/vm/profile.scm: * module/system/vm/disasm.scm: * module/system/vm/debug.scm: * module/system/vm/conv.scm: * module/system/vm/assemble.scm: * module/system/repl/repl.scm: * module/system/repl/common.scm: * module/system/base/compile.scm: * module/system/repl/command.scm: Update for changes, and fix a bug in procedure-documentation. * module/system/vm/bootstrap.scm: Just call scm_bootstrap_vm, which handles setting load-compiled for us. * module/system/vm/core.scm: Removed, functionality folded into other modules. * module/system/vm/frame.scm: Export the C frame procedures here; also move scheme functions from core.scm here. * module/system/vm/instruction.scm: New file, exports procedures from instructions.c. * module/system/vm/objcode.scm: New file, exports procedures from objcodes.c. * module/system/vm/program.scm: New file, exports procedures from programs.c, and some scheme functions originally from core.scm. * module/system/vm/vm.scm: New file, from vm.c and core.scm. * src/Makefile.am (libguile_vm_la_SOURCES): Add bootstrap.h. * src/bootstrap.h: New file, prototypes scm_bootstrap_vm (), which the scm_init_* functions call. * src/frames.h: * src/frames.c (scm_init_frames): * src/frames.c (scm_bootstrap_frames): * src/vm.h: * src/instructions.h: * src/instructions.c (scm_init_instructions): * src/instructions.c (scm_bootstrap_instructions): * src/objcodes.h: * src/objcodes.c (scm_bootstrap_objcodes): * src/objcodes.c (scm_init_objcodes): * src/programs.h: * src/programs.c (scm_bootstrap_programs): * src/programs.c (scm_init_programs): * src/vm.c (scm_bootstrap_vm): * src/vm.c (scm_init_vm): Call scm_bootstrap_vm() before doing anything in an init function. Bootstrap_vm will call bootstrap_instructions(), etc to initialize types, then set load-compiled to point to load-compiled/vm. * src/vm.c (scm_load_compiled_with_vm): Code to load .go files, if they're present.
