* libguile/continuations.h (scm_t_contregs): Remove "struct vm*" member;
unneeded.
* libguile/continuations.c (scm_i_make_continuation): No need to store
continuation->vp.
(scm_i_contregs): New internal function, replaces scm_i_contregs_vp
and scm_i_contregs_vm_cont.
(scm_i_check_continuation): Remove; moved to vm.c.
(scm_i_reinstate_continuation): Add an abort(), to satisfy
SCM_NORETURN.
* libguile/intrinsics.h: Add new "reinstate-continuation!" intrinsic.
* libguile/vm-engine.c (continuation-call): Use new
reinstate-continuation! intrinsic.
* libguile/vm.c (vm_return_to_continuation_inner): Move later in the
file.
(reinstate_continuation_x): New intrinsic.
(scm_bootstrap_vm): Init new intrinsic.
* libguile/intrinsics.h (SCM_FOR_ALL_VM_INTRINSICS): Add
push-interrupt-frame.
* libguile/vm.c (push_interrupt_frame): New intrinsic. Goal is to
reduce the amount of inline code the JIT will generate for handling
interrupts.
* libguile/vm-engine.c (handle-interrupts): Call out to the
push_interrupt_frame intrinsic in the slow case.
* libguile/intrinsics.h (scm_t_thread_sp_intrinsic): Change to take
thread instead of vp.
(SCM_FOR_ALL_VM_INTRINSICS): Change expand_stack to expect thread, not
vp.
* libguile/vm-engine.c (ALLOC_FRAME): Call expand_stack with thread.

* libguile/vm.c (scm_t_vm_engine, scm_call_n): Remove "vp" argument.

all uses of vp with this.
* libguile/threads.c (thread_mark): Unconditionally call
scm_i_vm_mark_stack.
(guilify_self_1): Eagerly prepare the thread stack, before entering
Guile mode. It's only a page of mmap, after all.
* libguile/vm.c (scm_i_vm_prepare_stack): Rename from init_vm.
(thread_vm, scm_the_vm): Remove.
(VM_DEFINE_HOOK, scm_vm_trace_level, scm_set_vm_trace_level_x)

* libguile/throw.c (catch, abort_to_prompt): Get VM from thread.
As the FSF advises, 'There is no legal significance to using the
three-character sequence “(C)”, but it does no harm.' It does take up
space though! For that reason, we remove it here from our C files.
* libguile/foreign.c (ROUND_UP): Copy here.
* libguile/vm.c (SCM_NOINLINE): Move here, to the only file that uses
it.
(ROUND_UP): Copy here.
* libguile/_scm.h (ROUND_UP, SCM_NOINLINE): Remove. Centralizing
private definitions isn't bad, but _scm.h also includes a bunch of
Guile API as well, and the include itself is poorly named.
* libguile/__scm.h (scm_i_jmp_buf): Remove definition, which was a shim
for ia64. Instead, always use setjmp/longjmp and jmp_buf.
* libguile/_scm.h (SCM_I_SETJMP, SCM_I_LONGJMP): Remove; instead use
setjmp and longjmp.

(restore_auxiliary_stack): New helpers.
(scm_i_make_continuation): Use capture_auxiliary_stack.

the aux stack on the thread, either.
* libguile/continuations.h (scm_t_contregs): Use
SCM_HAVE_AUXILIARY_STACK to flag when to have an auxiliary_stack
member.
* libguile/control.h:
* libguile/control.c (reify_partial_continuation, scm_c_abort):
(scm_suspendable_continuation_p): Adapt to use setjmp/longjmp
directly.
* libguile/deprecated.h: Add deprecated scm_i_jmp_buf define.
* libguile/dynstack.h:
* libguile/dynstack.c (PROMPT_JMPBUF):
(scm_dynstack_push_prompt, scm_dynstack_find_prompt):
(scm_dynstack_wind_prompt): Adapt to jmp_buf type.
* libguile/eval.c (eval): Use jmp_buf and setjmp directly.
* libguile/gc-malloc.c: No need for ia64-specific things.
* libguile/gc.c: No need for ia64-specific things.
* libguile/gc.h: No need to declare scm_ia64_ar_bsp.
* libguile/init.c: Remove typedef of setjmp_type for Cray, unused.
* libguile/threads.c (guilify_self_1): No more pending_rbs_continuation
in scm_i_thread, and register_backing_store_base is handled by libgc.
(scm_ia64_ar_bsp): Remove definitions; inlined into continuations.c's
capture_auxiliary_stack.
* libguile/threads.h (scm_i_thread): jmpbuf member is plain jmp_buf.
* libguile/throw.c (catch): Just use jmp_buf and setjmp.
* libguile/vm-engine.c (VM_NAME): Adapt prototype to take jmp_buf
pointer.

(scm_call_n): Use setjmp.
* libguile/bytevectors.h: Include uniform.h, for use in the macros.
* libguile/extensions.h: Include libpath.h, for the
SCM_EFFECTIVE_VERSION, which is almost always used with these
routines.
* libguile/frames.h:
* libguile/instructions.h:
* libguile/intrinsics.h:
* libguile/loader.h:
* libguile/programs.h:
* libguile/vm.h: Include <libguile/__scm.h> instead of <libguile.h>.
Cuts a circular include, but also precipitates a lot of maintenance in
the .c files.
* libguile/*.c: Update C files to add needed all needed includes that
before were getting automatically pulled in by the indirect inclusion
of libguile.h.
* libguile/intrinsics.h: Rename intrinsic types added in previous
commit.
* libguile/vm-engine.c (call-scm<-scm-scm, call-scm<-scm-uimm): New
instructions.
* libguile/vm.c: Include intrinsics.h.

(gc-pointer-set!/immediate): New instructions.
(SP_REF_PTR, SP_SET_PTR): New helper definitions.
* libguile/vm.c (SLOT_DESC_LIVE_GC): Rename from SLOT_DESC_LIVE_SCM, as
it can indicate GC-protected raw pointers also.
(scm_i_vm_mark_stack): Adapt.
* module/system/vm/assembler.scm (write-arities):
* module/system/vm/debug.scm (arity-definitions): Add gcptr
representation. This is a binary-incompatible change!
* libguile/vm.c (vm_dispatch_hook): Save the compare result before
calling out to the hook. This only really matters for the "next"
hook, which can be called between a compare and its corresponding
branch instruction.
* libguile/throw.h (scm_ithrow, scm_throw): Mark as SCM_NORETURN.
* libguile/throw.c (scm_throw, scm_ithrow): Adapt to not return.

argument. Unless the vector handle is mutable, null out its
writable_elements member.
(scm_array_get_handle): Adapt to determine mutability of the various
arrays.
(scm_array_handle_elements, scm_array_handle_writable_elements):
Reverse the sense: instead of implementing read-only in terms of
read-write, go the other way around, adding an assertion in the
read-write case that the array handle is mutable.
* libguile/array-map.c (racp): Assert that the destination is mutable.
* libguile/bitvectors.c (SCM_F_BITVECTOR_IMMUTABLE, IS_BITVECTOR):
(IS_MUTABLE_BITVECTOR): Add a flag to indicate immutability.
