* m4/labels-as-values.m4: New file, checks for computed goto.
* configure.in: Use AC_C_LABELS_AS_VALUES.
* module/system/repl/command.scm (procedure-documentation): Extend the
core's procedure-documentation in an ad-hoc way, so that ,help works.
* module/system/vm/core.scm (program-properties): New function.
(program-documentation): New function.
* src/vm_engine.h (DROP, DROPN): Decrement sp before checking for
underflow.
* src/vm_system.c (call, tail-call): Add some optimized dispatch for some
C functions, so that we can avoid consing and the interpreter if
possible. However currently it seems that I'm always getting the
scm_call_* trampolines back.
* benchmark/lib.scm: Add a comment, update the loop disassembly. Loop is
now faster in the VM, thankfully.
* src/vm_engine.h (CACHE_PROGRAM): Only release and regrab the object
array handle if the program changed. That is to say, optimize the
self-tail-recursive case. But perhaps the thing to optimize here are
the procedure calls themselves. Worth looking at in the future.
* doc/guile-vm.texi: Documented the compiler (node `The Compiler').
Removed a number of things that might have been relevant to Guile-VM 0.0.
* module/system/il/compile.scm (optimize): Commented out the case
using `<ghil-inst?>'.
* src/vm_engine.c (vm_run)[objects_handle]: New variable.
Before leaving the function, release OBJECTS_HANDLE.
* src/vm_engine.h (CACHE_PROGRAM): Use `scm_vector_writable_elements'
instead of `scm_vector_elements'; don't release the handle right away.
* src/vm_loader.c (load-program): New commented out piece of code
dealing with simple vectors.
* src/vm_system.c (object-ref): Added the type of OBJNUM.

object file is too small.
* doc/guile-vm.texi: Documented `make-closure'. Improved the documentation
of `load-program'.
* testsuite: New directory.
* configure.in: Added `testsuite/Makefile' to `AC_OUTPUT'.
* Makefile.am (SUBDIRS): Added `testsuite'.
* src/vm_engine.h (VM_CHECK_OBJECT): New option.
(CHECK_OBJECT): New macro.
* src/vm_system.c (object-ref): Use VM_CHECK_OBJECT.
* module/system/vm/assemble.scm (preprocess): Commented out the debugging
code.
* benchmark/lib.scm (do-loop): New procedure.
git-archimport-id: lcourtes@laas.fr--2005-mobile/guile-vm--mobile--0.6--patch-2
* src/objcodes.c (do-pair): New experiment.
* src/vm_engine.h (ALIGN_AS_NON_IMMEDIATE): New macro.
(POP_LIST_ON_STACK): New experimental macro.
* src/vm_engine.c (call): In the procedure call case, I tried using the above
macro.
git-archimport-id: lcourtes@laas.fr--2004-libre/guile-vm--revival--0.6--patch-8
* src/*.[ch]: Replaced `scm_mem2symbol' by `scm_from_locale_symboln' and
`scm_ulong2num' by `scm_from_ulong'.
* src/vm_system.c (tail-call): Fixed stack leak (SP lacked decrement by
one more Scheme object in the tail-recursive case).
* benchmark/measure.scm (measure): Make sure we are using the compiled
procedure (i.e. a program object) when measuring. This yields better
results than before. :-)
* doc/guile-vm.texi: Augmented the instruction set documentation with
branch instructions, `call' and `tail-call'.
git-archimport-id: lcourtes@laas.fr--2004-libre/guile-vm--revival--0.6--patch-7
* benchmark/lib.scm: New file.
* benchmark/measure.scm: New file.
* README: Added useful pointers to various threads.
* doc/guile-vm.texi: Fixed the description of `load-program' (it now expects
_immediate_ integers).
* src/*.[ch]: Use immediate integers whereever possible, as in the original
code. For `CONS', use `scm_cell' rather than `scm_cons'.
git-archimport-id: lcourtes@laas.fr--2004-libre/guile-vm--revival--0.6--patch-6
* src/*.[ch]: Replaced the remaining `SCM_MAKINUM', and changed `SCM_VELTS'
into `scm_vector_elements ()'.
* src/vm_loader.c (link): Fixed so that it pushed a variable object on
the stack.
* src/vm_system.c (variable-ref): Fixed so that it uses `scm_variable_ref ()'
and friends.
* module/system/vm/assemble.scm (dump-object!): Fixed the string case.
* src/vm_engine.h (CONS): Use `scm_cons' instead of `SCM_NEWCELL'.
* doc/guile-vm.texi: Added actual instruction definitions, explanations of
the program invocation mechanism, programs' object tables, etc., in the
`Instruction Set' chapter.
