Revision 40703

  • gc.c: support RGENGC. [ruby-trunk - Feature #8339] See this ticet about RGENGC.
  • gc.c: Add several flags:
  • RGENGC_DEBUG: if >0, then prints debug information.
  • RGENGC_CHECK_MODE: if >0, add assertions.
  • RGENGC_PROFILE: if >0, add profiling features. check GC.stat and GC::Profiler.
  • include/ruby/ruby.h: disable RGENGC by default (USE_RGENGC == 0).
  • array.c: add write barriers for T_ARRAY and generate sunny objects.
  • include/ruby/ruby.h (RARRAY_PTR_USE): added. Use this macro if you want to access raw pointers. If you modify the contents which pointer pointed, then you need to care write barrier.
  • bignum.c, marshal.c, random.c: generate T_BIGNUM sunny objects.
  • complex.c, include/ruby/ruby.h: add write barriers for T_COMPLEX and generate sunny objects.
  • rational.c (nurat_s_new_internal), include/ruby/ruby.h: add write barriers for T_RATIONAL and generate sunny objects.
  • internal.h: add write barriers for RBasic::klass.
  • numeric.c (rb_float_new_in_heap): generate sunny T_FLOAT objects.
  • object.c (rb_class_allocate_instance), range.c: generate sunny T_OBJECT objects.
  • string.c: add write barriers for T_STRING and generate sunny objects.
  • variable.c: add write barriers for ivars.
  • vm_insnhelper.c (vm_setivar): ditto.
  • include/ruby/ruby.h, debug.c: use two flags FL_WB_PROTECTED and FL_OLDGEN.
  • node.h (NODE_FL_CREF_PUSHED_BY_EVAL, NODE_FL_CREF_OMOD_SHARED): move flag bits.
