* module/system/base/syntax.scm (keywords): Don't enable :keywords, it
breaks code that may assume that ':foo is a symbol, like boot-9.
* module/*.scm: Don't use :keywords, use #:keywords. The user can decide
if she wants #:keywords in their .guile, and :keywords might make us
compile modules differently.
* module/system/vm/assemble.scm (make-meta, codegen): Hide the "meta"
information -- the names of the bindings, source info, procedure
properties, etc -- behind a lambda. This way, loading up a program
conses less, because the metadata stays as mmap'd code until it is
needed.
* libguile/vm-i-loader.c (load-program): Adjust load-program to expect
the metadata to be a program.
* module/system/vm/program.scm (program-bindings, program-sources)
(program-properties): Adjust to new meta format.
* 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?
* module/system/il/compile.scm (codegen): The currently-executing
instruction is actually the one right before the instruction pointer;
so for purposes of assv to find a source location for an ip, put the
source after the code, as it was before.
* module/system/vm/debug.scm (vm-backtrace): Move more code to frame.scm.
* module/system/vm/frame.scm (make-frame-chain): Include all frames, even
the bootstrap one. For a reentrant backtrace we'll have boostrap
programs anyway. Probably should check for objcode[2] == scm_op_halt,
to not show those frames in the trace.
(frame-line-number, frame-file): New helpers.
(print-frame): Print out the line number too.
(frame-call-representation): Code from print-frame-call moved here.
(print-frame-chain-as-backtrace): A backtrace printer, yays.
(program-name): Check link validity before calling frame-address on it.
* module/system/vm/program.scm (source:addr, source:line, source:column)
(source:file): New accessors for the elements of program-sources.
* module/system/vm/vm.scm (vm:last-ip): New export.
(vm-last-frame-chain): Use vm:last-ip in making the frame chain.
* src/vm.h (struct scm_vm):
* src/vm.c (make_vm, scm_vm_last_ip, scm_vm_save_stack): Save the last
instruction pointer when saving the stack. Really though, we should be
saving all of the stack data on a spaghetti stack.
* src/vm_system.c (late-variable-ref): Pointless s/REGISTER/BEFORE_GC/.
* module/system/repl/command.scm: Coerce rationals to floats.
* module/system/vm/program.scm (program-documentation): Fix a typo, doh!
* src/vm.c (vm_reset_stack, struct vm_unwind_data): Add unwind handler to
reset vp->sp, vp->fp, and vp->this_frame when performing a nonlocal
exit from a vm_run.
(vm_heapify_frames_1): Don't repack the stack, it causes stack
corruption. I think we need spaghetti stacks to handle continuations,
not separate heap frames. I don't think call/cc is working now.
(vm-save-stack): Don't call heapify_frames, that modifies the stack
that we're copying. Instead call its helper, heapify_1.
* src/vm_engine.c (vm_run): Set up the vm_reset_stack unwind handler.
* src/vm_engine.h (IP_REG, SP_REG, FP_REG): If we got through all of the
checks without having these macros defined, define them as empty.
Happens on x86-64.
* src/vm_system.c (halt): End the dynwind before we return from the VM.
* src/vm_scheme.c (REL): Sync the regs before calling scm_lt_p et al,
cause they can do a nonlocal exit.
This reorganization kills the ugly module-export-all hacks in
bootstrap.scm and core.scm. In fact, it gets rid of core.scm entirely,
breaking out its functionality into separate files.
* module/system/vm/trace.scm:
* module/system/vm/profile.scm:
* module/system/vm/disasm.scm:
* module/system/vm/debug.scm:
* module/system/vm/conv.scm:
* module/system/vm/assemble.scm:
* module/system/repl/repl.scm:
* module/system/repl/common.scm:
* module/system/base/compile.scm:
* module/system/repl/command.scm: Update for changes, and fix a bug in
procedure-documentation.
* module/system/vm/bootstrap.scm: Just call scm_bootstrap_vm, which
handles setting load-compiled for us.
* module/system/vm/core.scm: Removed, functionality folded into other
modules.
* module/system/vm/frame.scm: Export the C frame procedures here; also
move scheme functions from core.scm here.
* module/system/vm/instruction.scm: New file, exports procedures from
instructions.c.
* module/system/vm/objcode.scm: New file, exports procedures from
objcodes.c.
* module/system/vm/program.scm: New file, exports procedures from
programs.c, and some scheme functions originally from core.scm.
* module/system/vm/vm.scm: New file, from vm.c and core.scm.
* src/Makefile.am (libguile_vm_la_SOURCES): Add bootstrap.h.
* src/bootstrap.h: New file, prototypes scm_bootstrap_vm (), which the
scm_init_* functions call.
* src/frames.h:
* src/frames.c (scm_init_frames):
* src/frames.c (scm_bootstrap_frames):
* src/vm.h:
* src/instructions.h:
* src/instructions.c (scm_init_instructions):
* src/instructions.c (scm_bootstrap_instructions):
* src/objcodes.h:
* src/objcodes.c (scm_bootstrap_objcodes):
* src/objcodes.c (scm_init_objcodes):
* src/programs.h:
* src/programs.c (scm_bootstrap_programs):
* src/programs.c (scm_init_programs):
* src/vm.c (scm_bootstrap_vm):
* src/vm.c (scm_init_vm): Call scm_bootstrap_vm() before doing anything
in an init function. Bootstrap_vm will call bootstrap_instructions(),
etc to initialize types, then set load-compiled to point to
load-compiled/vm.
* src/vm.c (scm_load_compiled_with_vm): Code to load .go files, if
they're present.
