* libguile/vm-engine.c: Remove VM_HANDLE_INTERRUPTS before entering a
subr or foreign call. The bytecode stub will have already done so
when entering the stub, and the return sequence handles doing so
before returning.
* module/system/vm/trace.scm (print-return): Remove frame argument.
(trace-calls-to-procedure, trace-calls-in-procedure): Adapt callers.
* module/system/vm/traps.scm (trap-in-procedure, trap-frame-finish):
(trap-calls-to-procedure): Since the pop continuation hook is now
called after the continuation is popped, we need to check the right
frame. Fixes tail-calls in the trace root, and probably other things.
* module/language/cps/slot-allocation.scm (lookup-dead-slot-map)
(allocate-slots): For each non-tail call in a function, compute the
set of slots that are dead after the function has begun the call.
* module/language/cps/compile-bytecode.scm (compile-fun): Emit the
`dead-slot-map' macro instruction for non-tail calls.
* module/system/vm/assembler.scm (<asm>): Add `dead-slot-maps' member.
(dead-slot-map): New macro-instruction.
(link-frame-maps, link-dynamic-section, link-objects): Write dead
slots information into .guile.frame-maps sections of ELF files.
* module/system/vm/elf.scm (DT_GUILE_FRAME_MAPS): New definition.
* libguile/loader.h:
* libguile/loader.c (DT_GUILE_FRAME_MAPS, process_dynamic_segment):
(load_thunk_from_memory, register_elf): Arrange to parse
DT_GUILE_FRAME_MAPS out of the dynamic section.
(find_mapped_elf_image_unlocked, find_mapped_elf_image): New helpers.
(scm_find_mapped_elf_image): Refactor.
(scm_find_dead_slot_map_unlocked): New interface.
* libguile/vm.c (scm_i_vm_mark_stack): Mark the hottest frame
conservatively, as before. Otherwise use the dead slots map, if
available, to avoid marking data that isn't live.
* module/ice-9/boot-9.scm:
* module/ice-9/i18n.scm:
* module/ice-9/poll.scm:

* module/oop/goops/dispatch.scm:
* module/srfi/srfi-88.scm:
* module/system/foreign.scm:
* module/texinfo/serialize.scm: Change most uses of 'compile' to
'expand', except where we must avoid it during initial bootstrap
before the module system is loaded. Remove redundant uses of
'compile' where 'expand' is also given. Standardize on the
"(expand load eval)" order of conditions.
* doc/ref/api-macros.texi (Eval When): Explain in detail what each
condition means, including 'expand' which was previously undocumented.
Change the example to use (expand load eval) and recommend that set of
conditions, instead of (compile load eval) which was previously
recommended and shown in the example.

bytevector if not; copy the data back from BV to c_port->read_pos.
Remove 'again' label, and don't loop there.

* libguile/ports.c (scm_new_port_table_entry): Clear 'pti->setvbuf'.
* libguile/fports.c (scm_setvbuf): Accept any open port, and error out
when PORT's setvbuf' field is NULL. Remove explicit 'scm_gc_free' calls.

* test-suite/tests/ports.test ("setvbuf")["closed port", "string port"]:
New tests.
