* libguile/vm-engine.c (vm_run): Move nvalues to the top level, to avoid
(spurious, it seems) gcc warnings about it being used uninitialized.
* libguile/vm-i-system.c (halt, return/values): Adapt to gcc silliness.
Deindent some of return/values.
(return/values*): New instruction, does what (apply values . args)
would do.
* module/language/scheme/translate.scm (custom-transformer-table): Move
the apply and @apply cases here from inline.scm, because we need some
more cleverness when dealing with cases like (apply values . args).
(lookup-apply-transformer): Define an eval transformer for `values',
turning it into ghil-values*.
* module/system/il/compile.scm (codegen): Compile <ghil-values*> into
return/values*.
* module/system/il/ghil.scm: Add <ghil-values*> and accessors.
(ghil-lookup): Add optional argument, define?, which if false tells us
not to actually cache the binding if it is not found in the toplevel.
* module/system/il/inline.scm: Remove apply clauses.
* module/system/vm/frame.scm (bootstrap-frame?): Update heuristic for
bootstrap-frame?, as the bootstrap frame is now 5 bytes since it
accepts multiple values.
* libguile/vm-engine.c (vm_run): The bootstrap program now uses mv_call,
so as to allow multiple values out of the VM. (It did before, because
multiple values were represented internally as single scm_values
objects, but now that values go on the stack, we need to note the boot
frame as accepting multiple values.)
(vm_error_no_values): New error, happens if you pass no values into a
single-value continuation. Passing more than one is OK though, it just
takes the first one.
* libguile/vm-i-system.c (halt): Assume that someone has pushed the
number of values onto the stack, and package up that number of values
as a scm_values() object, for communication with the interpreter.
(mv-call): New instruction, calls a procedure with a multiple-value
continuation, even handling calls out to the interpreter.
(return/values): New instruction, returns multiple values to the
continuation. If the continuation is single-valued, takes the first
value or errors if there are no values. Otherwise it returns to the
multiple-value return address, pushing the number of values on top of
the values.
* module/system/il/compile.scm (codegen): Compile <ghil-values> forms.
* module/system/il/ghil.scm (<ghil-values>) Add new GHIL data structure
and associated procedures.
* module/language/scheme/translate.scm (custom-transformer-table):
Compile (values .. ) forms into <ghil-values>.
* 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/objcodes.h:
* libguile/programs.c:
* libguile/programs.h:
* libguile/vm-bootstrap.h: (was bootstrap.h)
* libguile/vm-engine.c: (was vm_engine.c)
* libguile/vm-engine.h: (was vm_engine.h)
* libguile/vm-expand.h: (was vm_expand.h)
* libguile/vm-i-loader.c: (was vm_loader.c)
* libguile/vm-i-scheme.c: (was vm_scheme.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/bootstrap.scm:
* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm:
* pre-inst-guile-env.in: Add builddirs to the load path; add module/ to
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.
* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm: Call the init functions in libguile; should
fix at some point to avoid the dlopen?
