* gc.c (rb_gc_force_recycle): Add a missing space around a parenthesis.

is before sweep?
* gc.c (rb_gc_force_recycle): Have to clear mark bit if object's slot
already ready to mainor sweep.

* gc.c (gc_marks_test): Check all WriteBarrier Errors and track them in obj-tree.
* gc.c (rgengc_check_shady): Ditto.
* gc.c (gc_marks): Move 2 funtion calls to gc_marks_test for test initialize.

* gc.c (gc_prof_timer_start): Pick out part of new record creation as gc_prof_setup_new_record.
* gc.c (gc_prof_set_malloc_info): Move point of recording allocation size to front of mark.

on RGENGC_CHECK_MODE >= 2.
(1) Save bitmaps before marking
(2) Run full marking
(3) On each traceable object,
(a) object was not oldgen (== newly or shady object) &&
(b) parent object was oldgen &&
(c) parent object was not remembered &&
(d) object was not rememberd
then, it should be WB miss.
This idea of this checker is by Masaya Tarui <tarui@ruby-lang.org>.

gc_prof_set_heap_info() just after sweeping to calculate
live object number correctly.
(live object number = total generated number (before marking) -
total freed number (after sweeping))
* gc.c (gc_marks): record `oldgen_object_count' into current profile`
record directly.
* gc.c (rgengc_rememberset_mark): same for remembered_normal_objects
and remembered_shady_objects.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41552 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
records (because it points a set of records) and add a field
rb_objspace::profile::current_record to point a current profiling
record.
* gc.c: use above fields.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41551 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
because all of remembered objects are called for gc_mark_children().

remembered objects directly instead of pushing on the mark stack.

No need to separate major/minor GC.
* gc.c (gc_setup_mark_bits): remove gc_clear_mark_bits() and unify to
this function.

Use RARRAY_ASET() or RARRAY_PTR_USE() to modify Array objects.
* array.c, gc.c: catch up above changes.

Introduce the following C APIs:
* RSTRUCT_RAWPTR(st) returns pointer (do WB on your risk).
The type of returned pointer is (const VALUE *).
* RSTRUCT_GET(st, idx) returns idx-th value of struct.
* RSTRUCT_SET(st, idx, v) set idx-th value by v with WB.
And
* RSTRUCT_PTR(st) returns pointer with shady operation.
The type of returned pointer is (VALUE *).
* struct.c, re.c, gc.c, marshal.c: rewrite with above APIs.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41534 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
disabled.
* gc.c (gc_marks_test): store oldgen count and shady count
before test marking and restore them after marking.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41526 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
(1) normal objects count in remember set
(2) shady objects count in remember set
each GC timing.
* gc.c (gc_profile_record_get): enable to access above information
and REMOVING_OBJECTS, EMPTY_OBJECTS.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41493 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* gc.c (ruby_initial_gc_stress_ptr): now gc_stress is a VALUE.

When RGENGC_CHECK_MODE >= 2, all minor marking, run normal minor
marking *and* major/full marking. After that, compare the results
and shows BUG if a object living with major/full marking but dead
with minor marking.
After detecting bugs, print references information.
(RGENGC_CHECK_MODE == 2, show references to dead object)
(RGENGC_CHECK_MODE == 3, show all references)
