46d2d6f80e allocate variables that are set! on the heap
* module/system/il/ghil.scm (ghil-lookup): So, it turns out this function
  needed to be split into three:
  (ghil-var-is-bound?, ghil-var-for-ref!, ghil-var-for-set!): The
  different facets of ghil-lookup. Amply commented in the source. The
  difference being that we now allocate variables that are set! on the
  heap, so that other continuations see their possibly-modified values.
  (force-heap-allocation!): New helper.

* testsuite/Makefile.am:
* testsuite/t-call-cc.scm: New test, that variables that are set! are
  allocated on the heap, so that subsequent modifications are still
  seen by the continuation. The test was distilled from test 7.3 in
  r5rs_pitfall.test.

535ed4d041 fix *another* bug in compiling `or'. incredible.
* module/system/il/compile.scm (codegen): Fix *another* bug in compiling
  `or' -- in the case in which the value was being discarded, as in `or'
  used as a control structure, we were sometimes leaving a value on the
  stack.

* testsuite/t-or.scm: Add another test case for `or'.

  (trans-quasiquote): Fix handling of nested quasiquotes.

* testsuite/Makefile.am (vm_test_files):
* testsuite/t-quasiquote.scm: Add a quasiquote test case.

83495480e8 merge guile-vm into libguile itself
* ice-9/boot-9.scm: Only define load-compiled as #f if it's not already
  defined, which won't normally be the case.

* libguile/guile-vm.c: Removed, there's no more guile-vm binary.

* libguile/frames.c: (with change frame? -> heap-frame?)
* libguile/frames.h:
* libguile/instructions.c:
* libguile/instructions.h:
* libguile/objcodes.c:

* libguile/vm-i-system.c: (was vm_system.c)
* libguile/vm.c:
* libguile/vm.h: These files moved here from src/, as guile-vm is now a
  part of libguile.

* libguile/init.c: Bootstrap the VM. Yay!

* libguile/Makefile.am: The necessary chicanery here.

* module/system/vm/Makefile.am:

* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:

  the path in the empty-$GUILE_LOAD_PATH case as well.

* src/Makefile.am: Moved out everything except guilec and guile-disasm,
  which probably should be moved to the scripts directory?

* testsuite/Makefile.am: Update to find guile-vm in the right place.

* module/system/vm/Makefile.am:
* module/system/vm/bootstrap.scm: Removed bootstrap.scm, scm_init_guile
  handles the bootstrapping for us.

7e4760e413 fix bug in compilation of and' and or'; more robust underflow detection.
* module/system/il/compile.scm (codegen): Rewrite handling of `and' and
  `or' ghil compilation, because it was broken if drop was #t. Tricky
  bug, this one! Took me days to track down!

* module/system/repl/repl.scm: Export call-with-backtrace, which probably
  should go in some other file.

* src/vm.c (scm_vm_save_stack): Handle the fp==0 case for errors before
  we have a frame.

* src/vm_engine.h (NEW_FRAME, FREE_FRAME): Stricter underflow checking,
  raising the stack base to the return address, in an attempt to prevent
  inadvertant stack smashing (the symptom of the and/or miscompilation
  bug).
  (CHECK_IP): A check that the current IP is within the bounds of the
  current program. Not normally compiled in. Perhaps it should be?

* src/vm_system.c (halt): Set vp->ip to NULL. Paranoia, I know.
  (return): Call CHECK_IP(), if such a thing is compiled in.

* testsuite/Makefile.am (vm_test_files):
* testsuite/t-catch.scm:
* testsuite/t-map.scm:
* testsuite/t-or.scm: New tests.

b571a648d5 fix distcheck
* src/Makefile.am (AM_CFLAGS, libguile_vm_la_LDFLAGS): Don't build with
  -pg. (There are better profilers out there.)
  (CLEANFILES): Add guilev and guile-disasm.

* testsuite/Makefile.am (GUILE_VM): s/srcdir/builddir/.

6297d22907 bind all module-level variables lazily
comments in ghil-lookup are pertinent.

* module/system/il/compile.scm (make-glil-var): Require that ghil vars
  have environments. Remove the 'unresolved case -- we'll treat all
  module-level variables as late bound.

* module/system/il/ghil.scm (ghil-lookup): Treat all module level vars as
  late bound.

* module/system/vm/assemble.scm: Instead of vlink and vlate-bound, have
  vlink-now and vlink-later.
  (codegen): Add a bunch of crap to get the various cases right.
  (object-assoc, dump-object!): Handle the new cases, remove the old
  cases.

* src/vm_loader.c (link-now, link-later): Change from link and lazy-bind.
  Include the module in which the link is to be done, so that callers
  from other modules get the right behavior.

* src/vm_system.c (late-variable-ref, late-variable-set): Instead of a
  sym, the unbound representation is a module name / symbol pair.

* testsuite/run-vm-tests.scm (run-vm-tests): Remove some debugging.

9cc649b880 Add instructions for doing very late binding
Fixes the mutually-recursive toplevel definitions case. This could be
fixed by rewriting bodies as letrecs, as r6 does, but that's not really
repl-compatible.

* module/system/il/ghil.scm (ghil-lookup): Ok, if we can't locate a
  variable, mark it as unresolved.

* module/system/il/compile.scm (make-glil-var): Compile unresolved
  variables as <glil-late-bound> objects.

* module/system/il/glil.scm: Add <glil-late-bound> definition.

* module/system/vm/assemble.scm (codegen): And, finally, when we see a
  <vlate-bound> object, allocate a slot for it in the object vector,
  setting it to a symbol. Add a new pair of instructions to resolve that
  symbol to a variable at the last minute.

* src/vm_loader.c (load-number): Bugfix: the radix argument should be
  SCM_UNDEFINED in order to default to 10.
  (late-bind): Add an unresolved symbol to the object vector. Could be
  replaced with load-symbol I guess.

* src/vm_system.c (late-variable-ref, late-variable-set): New
  instructions to do late symbol binding.

* testsuite/Makefile.am (vm_test_files):
* testsuite/t-mutual-toplevel-defines.scm: New test, failing for some
  reason involving the core even? and odd? definitions.

0658041d11 fix use-syntax / use-modules confusion -- fixes testsuites
* testsuite/t-match.scm:
* testsuite/t-records.scm: While the attempt to redefine use-syntax as
  being "use during compilation" was cute, it does not reflect the
  historical usage of use-syntax, nor does it correspond to existing code
  that includes other modules and uses them during compilation.

  So use-syntax has been replaced with use-modules. The test suites now
  pass. In the future, compilation phases should be done on whole
  modules, I think; r5rs-style computation does not have phases.

  (&current-macro-module): Removed.
  (&compile-time-module): New.
  (eval-at-compile-time): New.
  (translate): Initialize `&compile-time-module'.
  (expand-macro)[use-syntax]: New case.
  [begin let...]: Don't expand these built-in macros.
  [else]: Rewrote the macro detection and invocation logic.  Invoke macro
  transformers in the current compile-time module.
  (trans): Let `expand-macro' raise an exception if needed.
  (trans-pair)[defmacro define-macro]: Evaluate the macro definition in
  the compile-time module.

* testsuite/t-match.scm: Use `use-syntax' instead of `use-modules' for
  `(ice-9 match)' and `(srfi srfi-9)'.

23b587b0a1 Encode the length of constant lists/vectors on 2 octets instead of 1.
* module/system/vm/assemble.scm (dump-object!): New sub-procedure
  `too-long'.  For `list' and `vector', encode the length on 2 octets
  instead of 1 and report an error if a list/vector is longer than 65535.

* module/system/vm/disasm.scm (original-value): New sub-procedure
  `list-or-vector?'; when true, return the number of elements for that
  list/vector.

  (vector): Likewise.

* testsuite/t-basic-contructs.scm: New.

b6368dbbb9 Fixed a Scheme translation bug; cleaned compilation with GCC 4.
* module/language/scheme/translate.scm (trans-pair): In the `set!' case,
  when a procedure-with-setter is passed, call `trans:pair' with an
  actual pair.  This fixes a long-lasting bug which prevented compilation
  of `set!' statements with procedures-with-setter (this showed up when
  compiling `(system vm assemble)').

* module/system/base/compile.scm: Added `objcode->u8vector' to the
  `#:select' clause.

* module/system/base/syntax.scm: Cosmetic changes.

* module/system/vm/assemble.scm (preprocess): Removed debugging
  statements.

* src/frames.c: Cosmetic changes.

* src/frames.h (SCM_FRAME_SET_DYNAMIC_LINK): New.

* src/objcodes.c: Use `scm_t_uint8' instead of `char' when relevant.

* src/vm.c (vm_heapify_frames_1): Use `SCM_FRAME_SET_DYNAMIC_LINK ()'.

* src/vm_loader.c: Added casts to mute GCC 4 warnings.

* testsuite/run-vm-tests.scm (*scheme*): Renamed to `%scheme'.
  (run-test-from-file): Renamed to `compile/run-test-from-file'.
  (run-vm-tests): Run each test using both the VM and the interpreter;
  compare the results.

* testsuite/t-proc-with-setter.scm: Try out `get/set'.

* doc/Makefile.am (info_TEXINFOS): New.

* doc/guile-vm.texi: Added index entries and indices.

* doc/texinfo.tex: New file.

0b5f0e49a8 * src/objcodes.c (make_objcode_by_mmap): Fixed the error type when the
object file is too small.

* doc/guile-vm.texi:  Documented `make-closure'.  Improved the documentation
  of `load-program'.

* testsuite:  New directory.
