* libguile/vm-engine.c (rtl_vm_engine): Add new VM. (vm_engine): Add support for calling RTL programs. * libguile/tags.h (scm_tc7_rtl_program): New type for procedures that run on the new VM. * libguile/evalext.c (scm_self_evaluating_p): * libguile/goops.c (scm_class_of): * libguile/print.c (iprin1): * libguile/procprop.c (scm_i_procedure_arity): * libguile/procs.c (scm_procedure_p): Add hooks for the new tc7. * libguile/programs.h: * libguile/programs.c (scm_make_rtl_program, scm_i_rtl_program_print) (scm_rtl_program_p, scm_rtl_program_code): * module/system/vm/program.scm: Add constructors and accessors for the new "RTL programs". * libguile/vm.c (rtl_boot_continuation): Define a boot program. (rtl_apply, rtl_values): New static RTL programs. * libguile/frames.c (scm_frame_num_locals): Adapt for frames of RTL programs. * libguile/frames.h: Add description of RTL frames. * libguile/Makefile.am: Add rules to generate vm-operations.h. * .gitignore: Ignore vm-operations.h. * module/system/vm/instruction.scm: * libguile/instructions.c: * libguile/instructions.h: Use vm-operations.h to define enumerated values for the new RTL opcodes. Define some helper macros to pack and unpack 32-bit instruction words. (rtl-instruction-list): New function, exported by (system vm instruction). * libguile/objcodes.c: Wire up the bits needed to detect the new RTL bytecode and load it, as appropriate.
