From 123eeb1c1a904923754ce65148dbef045b56e083 Mon Sep 17 00:00:00 2001 From: ko1 Date: Mon, 8 Sep 2014 04:11:00 +0000 Subject: * gc.c: add incremental GC algorithm. [Feature #10137] Please refer this ticket for details. This change also introduces the following changes. * Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3). Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in RBasic::flags (2 bit). Age == 3 objects become old objects. * WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap. * LONG_LIVED bitmap to represent living objects while minor GCs It specifies (1) Old objects and (2) remembered shady objects. * Introduce rb_objspace_t::marked_objects which counts marked objects in current marking phase. marking count is needed to introduce incremental marking. * rename mark related function and sweep related function to gc_(marks|sweep)_(start|finish|step|rest|continue). * rename rgengc_report() to gc_report(). * Add obj_info() function to get cstr of object details. * Add MEASURE_LINE() macro to measure execution time of specific line. * and many small fixes. * include/ruby/ruby.h: add flag USE_RINCGC. Now USE_RINCGC can be set only with USE_RGENGC. * include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1 to count object age. * include/ruby/ruby.h: rewrite write barriers for incremental marking. * debug.c: catch up flag name changes. * internal.h: add rb_gc_writebarrier_remember() instead of rb_gc_writebarrier_remember_promoted(). * array.c (ary_memcpy0): use rb_gc_writebarrier_remember(). * array.c (rb_ary_modify): ditto. * hash.c (rb_hash_keys): ditto. * hash.c (rb_hash_values): ditto. * object.c (init_copy): use rb_copy_wb_protected_attribute() because FL_WB_PROTECTED is moved from RBasic::flags. * test/objspace/test_objspace.rb: catch up ObjectSpace.dump() changes. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47444 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- hash.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'hash.c') diff --git a/hash.c b/hash.c index 2e51a08d27..41e8ca4448 100644 --- a/hash.c +++ b/hash.c @@ -1781,7 +1781,7 @@ rb_hash_keys(VALUE hash) if (ST_DATA_COMPATIBLE_P(VALUE)) { st_table *table = RHASH(hash)->ntbl; - if (OBJ_PROMOTED(keys)) rb_gc_writebarrier_remember_promoted(keys); + rb_gc_writebarrier_remember(keys); RARRAY_PTR_USE(keys, ptr, { size = st_keys_check(table, ptr, size, Qundef); }); @@ -1825,7 +1825,7 @@ rb_hash_values(VALUE hash) if (ST_DATA_COMPATIBLE_P(VALUE)) { st_table *table = RHASH(hash)->ntbl; - if (OBJ_PROMOTED(values)) rb_gc_writebarrier_remember_promoted(values); + rb_gc_writebarrier_remember(values); RARRAY_PTR_USE(values, ptr, { size = st_values_check(table, ptr, size, Qundef); }); -- cgit v1.2.3
