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/guile-vm.c: Removed, there's no more guile-vm binary. * 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-bootstrap.h: (was bootstrap.h) * libguile/vm-engine.c: (was vm_engine.c) * libguile/vm-engine.h: (was vm_engine.h) * libguile/vm-expand.h: (was vm_expand.h) * libguile/vm-i-loader.c: (was vm_loader.c) * 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/bootstrap.scm: * 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: * module/system/vm/vm.scm: Call the init functions in libguile; should fix at some point to avoid the dlopen?
