* libguile/continuations.c (scm_i_continuation_to_frame): Adapt to vra field renaming. (scm_i_reinstate_continuation, grow_stack, copy_stack_and_call) (scm_dynthrow): Take mra of continuation. Set on the vp before the longjmp. * libguile/continuations.h: Update scm_i_reinstate_continuation prototype. * libguile/dynstack.h: * libguile/control.c (scm_suspendable_continuation_p): * libguile/dynstack.c (PROMPT_WORDS, PROMPT_VRA, PROMPT_MRA): (PROMPT_JMPBUF, scm_dynstack_push_prompt, scm_dynstack_find_prompt) (scm_dynstack_wind_prompt): Store both virtual and machine return addresses on the dynstack, for prompts. * libguile/eval.c (eval): Pass NULL for mra. * libguile/intrinsics.c (push_prompt): Add mra arg, and pass it to the dynstack. * libguile/intrinsics.h: Update prototypes so that continuation-related intrinsics can save and restore the MRA. * libguile/jit.h: * libguile/jit.c: Return VRA when JIT code needs to tier down. * libguile/stacks.c (find_prompt, scm_make_stack) * libguile/throw.c (catch): Adapt find-prompt calls. * libguile/vm-engine.c (instrument-entry, instrument-loop): Add logic to continue with vcode after the mcode finishes. (compose-continuation, capture-continuation, abort, prompt): Add logic to pass NULL as captured MRA, but continue with mcode from new continuations, if appropriate. * libguile/vm.c (scm_i_vm_cont_to_frame, capture_stack) (scm_i_capture_current_stack, reinstate_continuation_x) (capture_continuation, compose_continuation_inner, compose_continuation) (capture_delimited_continuation, abort_to_prompt): Adapt to plumb around machine code continuations. (scm_call_n): Check "mra_after_abort" field for machine code continuation, if any. * libguile/vm.h (struct scm_vm): Add "mra_after_abort" field. (struct scm_vm_cont): Rename "ra" field to "vra" and add "mra" field.
