* libguile/vm-i-loader.c (load-program):
* module/system/vm/assemble.scm (dump-object!): There are cases in which
we use the 16-bit representation for program params (nargs, nexts,
etc), but the actual 16-bit number actually fits into 8 bits -- which
is then misinterpreted by the loader as the 8-bit form. So ditch the
8-bit form entirely (it was never much of an optimization), and just
use the 16-bit form. Make sure to clear out all your .go files before
recompiling this one!
* libguile/vm-i-loader.c: A combination of superstition and a bugfix:
make sure that we treat bits as being of a type as wide as we think it
is, and, more importantly, allow for programs with 8 <= nargs < 16.
* libguile/vm-i-scheme.c (FUNC1): Remove, cause it's not used.
(FUNC2): Don't assume an inum can fit into an int, use scm_bits_t
instead. In reality though we should probably do use different checks,
i.e. for multiplication probably we overflow. (That would be a bug.)
Based on a patch by C. K. Jester-Young <cky944 <at> gmail.com>.
* 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?
* New file gc-segment-table.c: hold code for the segment table.
* Remove data that might be out of date; remove
scm_i_adjust_min_yield(). We don't store min_yields, since they
are only accurate at one point in time (when the sweep finishes).
We decide the min yield at that point from min_yield_fraction and
freelist->collected / freelist->swept
* Introduce scm_i_gc_heap_size_delta() replacing
scm_i_gc_grow_heap_p().
* Remove foo_1 fields containing penultimate results.
* After GC, count mark bit vector to discover number of live
objects. This simplifies hairy updates.
* Many formatting and layout cleanups.
* Fix in scm_i_sweep_card(): return the length of free_list returned,
rather than number of deleted objects.
* For mtrigger GCs: do not also run a full sweep after the gc() call, as
this is inconsistent with lazy sweeping.
* Remove scm_i_make_initial_segment().
* Use calloc in scm_i_make_empty_heap_segment() to save on
initialization code.
* New function scm_i_sweep_for_freelist() which sweeps, with proper
statistic variable updates.
* New segments are conceptually blocks with 100% reclaimable cells.
* Remove some useless constants/comments: SCM_HEAP_SIZE,
SCM_INIT_HEAP_SIZE, SCM_EXPHEAP, SCM_HEAP_SEG_SIZE
* Do not increment scm_cells_allocated() from the
scm_[double]cell(). This would be a race condition.
* Move some deprecation checks in separate functions to not distract
from main code flow.
