8b87567085 Fix 64->32 bit cross-compilation of large-ish fixnums
* module/system/vm/assembler.scm (immediate-bits): Fix a bug whereby
  compiling to a 32-bit target from a 64-bit host would treat all
  integers whose representation fit into 32 bits as immediates.  This
  would result in integer constants between #x20000000 and 0x3fffffff
  being residualized in such a way that they would be loaded as negative
  numbers.

8998f1539f Update statprof documentation; deprecate `with-statprof'
* module/statprof.scm: Remove most of the commentary, as it was
  duplicated in the manual and was getting out of date.
  (stats): Remove self-secs-per-call and cum-secs-per-call fields as
  they can be computed from the other fields.
  (statprof-call-data->stats): Adapt.
  (statprof-stats-self-secs-per-call):
  (statprof-stats-cum-secs-per-call): New functions.
  (statprof-display/flat): Don't print the seconds-per-call fields, as
  we are no longer stopping the clock around call counters.  Anyway
  these times were quite misleading.
  (with-statprof): Deprecate.  It took its keyword arguments at the
  beginning; very complicated!  Better to use the `statprof' function.
  (`statprof' was introduced after `with-statprof' and then
  `with-statprof' was adapted to use it.)

* doc/ref/statprof.texi (Statprof): Port this documentation away from
  the automatically generated text and update it for the new interfaces
  like #:display-style.

* module/system/base/syntax.scm (record-case): Remove comment that
  referenced with-statprof.  Add comment indicating that record-case
  should be replaced.

* doc/ref/scheme-using.texi (Profile Commands): Update to mention
  keyword arguments and to link to the statprof documentation.

cd0b61a04e Frame <binding> objects capture frame, can ref value directly
* module/system/repl/debug.scm (print-locals): Adapt to
  frame-binding-ref change.

* module/system/vm/frame.scm (<binding>): Add `frame' field.
  (available-bindings): Capture the frame.
  (binding-ref, binding-set!): New functions, accessing a local variable
  value directly from a frame.
  (frame-binding-ref, frame-binding-set!): Remove.  As these are very
  low-level debugging interfaces introduced in 2.0, never documented,
  and quite tied to the VM, we feel comfortable making this change.
  (frame-call-representation): Adapt to available-bindings change.
  (frame-environment, frame-object-binding): Adapt to binding-ref
  interface change.

* doc/ref/vm.texi (Stack Layout): Mention that slots can be re-used.
  Update disassembly in example.

* doc/ref/api-debug.texi (Frames): Remove documentation for
  frame-local-ref, frame-local-set!, and frame-num-locals.  Replace with
  documentation for frame-bindings, binding accessors, and binding-ref /
  binding-set!.

* libguile/frames.h (scm_frame_num_locals, scm_frame_local_ref)
  (scm_frame_local_set_x): Remove.  As long as we are changing the
  interface in a backward-incompatible way, we might as well remove
  these.
* libguile/frames.c (scm_frame_num_locals, scm_frame_local_ref)
  (scm_frame_local_set_x, scm_init_frames_builtins, scm_init_frames):
  Arrange to make frame-local-ref et al private to frames.scm.

* module/system/vm/frame.scm: Load scm_init_frames_builtins extensions.
  (frame-instruction-pointer-or-primitive-procedure-name): New public
  function.
  (frame-binding-ref, frame-binding-set!): Allow binding objects as
  vars.

* module/system/repl/debug.scm (print-locals): Pass binding directly to
  frame-binding-ref.

* module/statprof.scm (sample-stack-procs, count-call): Use new
  frame-instruction-pointer-or-primitive-procedure-name function.

e4be4aea34 Fix cross-compilation of immediates to targets with different word sizes
* module/system/vm/assembler.scm (immediate-bits): Rename from
  immediate?, and return the bits.  Take asm argument so that we measure
  what's an immediate not on the host but for the target.  Adapt all
  callers.
  (write-immediate): Take bits instead of SCM object.  Adapt callers.
  (write-placeholder): New helper, to write bits for #f.  Adapt callers
  that wrote #f to use write-placeholder.

8a39162160 Assembler O(n) in instruction encodings, not instruction count
* module/system/vm/assembler.scm: Change define encoders for all of the
  kinds of instructions and have the emit-foo procedures call the common
  encoders.  No change to public interface.  This decreases the amount
  of generated code in the assembler.

362907810b Fix emit-receive* for many locals

* module/system/vm/assembler.scm (u32-ref, u32-set!, s32-ref, s32-set!):
  Remove these helpers.
* module/system/vm/assembler.scm (<asm>): Track offsets in bytes, not
  u32 units.

* module/system/vm/assembler.scm (<asm>): Instead of writing words into
  a list of fixed-size buffers, use a growable vector.
  (expand, emit): Instead of assuming that there is enough space for
  only one word, check that there is space for the entire instruction at
  the beginning.

bdfa1c1b42 Add tagged and untagged arithmetic ops with immediate operands
* libguile/vm-engine.c (add/immediate, sub/immediate)
  (uadd/immediate, usub/immediate, umul/immediate): New instructions.
* module/language/cps/compile-bytecode.scm (compile-function):
* module/language/cps/slot-allocation.scm (compute-needs-slot):
* module/language/cps/types.scm:
* module/system/vm/assembler.scm (system):
* module/language/cps/effects-analysis.scm: Support
  for new instructions.

* module/language/cps/optimize.scm (optimize-first-order-cps): Move
  primcall specialization to the last step -- the only benefit of doing
  it earlier was easier reasoning about side effects, and we're already
  doing that in a more general way with (language cps types).
* module/language/cps/specialize-primcalls.scm (specialize-primcalls):
  Specialize add and sub to add/immediate and sub/immediate, and
  specialize u64 addition as well.  U64 specialization doesn't work now
  though because computing constant values doesn't work for U64s; oh
  well.

  with add/immediate and sub/immediate.
* module/language/tree-il/peval.scm (peval): If we reify a new
  <primcall>, expand it.  Removes 1- and similar primcalls.
* module/language/tree-il/primitives.scm: Don't specialize (+ x 1) to 1+.
  (expand-primcall): New export, does a single primcall expansion.
  (expand-primitives): Use the new helper.

a7e1c392c2 Remove frame->module
* module/system/repl/debug.scm (frame->module): Remove.  Has been broken
  for a while, had no callers, and was calling frame-procedure.  We can
  revive again in a better way, like ice-9 local-eval.

3582787cb0 VM traps don't match on value of slot 0
* module/system/vm/traps.scm (frame-matcher): Always match on a
  procedure's code, instead of the value in slot 0.  Prevents confusion
  with closure-optimized procedures, re-use of slot 0, and untagged
  values in slot 0.
  (trap-at-procedure-call, trap-in-procedure)
  (trap-instructions-in-procedure, trap-at-procedure-ip-in-range)
  (trap-at-source-location, trap-in-dynamic-extent)
  (trap-calls-in-dynamic-extent, trap-instructions-in-dynamic-extent):
  Update to adapt to frame-matcher change and remove #:closure?
  argument, effectively changing the default behavior to #:closure? #t.

* doc/ref/api-debug.texi (Low-Level Traps): Update documentation.

adb2329863 Remove `procedure' repl command
* doc/ref/scheme-using.texi (Debug Commands):
* module/system/repl/command.scm (procedure): Remove REPL command.
  Since there is a closure binding and we have improved the ,registers
  output, this is no longer necessary and by removing it we remove
  another bogus use of frame-procedure.

2d0214a9b7 ,registers doesn't use frame-procedure
* module/system/repl/debug.scm (print-registers): Avoid frame-procedure,
  and be more useful and print an offset in units of 4 bytes.

c960c76fe0 Better frame-call-representation printing of GC clobbers
* module/system/vm/frame.scm (frame-call-representation): Assume that
  unspecified values are GC clobbers rather than actual arguments, and
  print as _.

029af6f68a frame-call-representation avoids frame-procedure.
* module/system/vm/frame.scm (frame-call-representation): Never use
  frame-procedure, as we don't know that slot 0 is a SCM value and even
  if it were, we don't know that it corresponds to the procedure being
  applied, except in the case of primcalls.  Print _ as the procedure
  name if we don't know it, instead of #f.
