* include/ruby/ruby.h (struct RClass): Add wrapper struct around
RClass->m_tbl with serial. This prevents double marking method tables, since many classes/modules can share the same method table. This improves minor mark time in a large application by 30%. * internal.h (struct method_table_wrapper): Define new wrapper struct with additional serial. * internal.h (RCLASS_M_TBL_INIT): New macro for initializing method table wrapper and st_table. * method.h (void rb_sweep_method_entry): Rename rb_free_m_table to rb_free_m_tbl for consistentcy * .gdbinit (define rb_method_entry): Update rb_method_entry gdb helper for new method table structure. * class.c: Use RCLASS_M_TBL_WRAPPER and RCLASS_M_TBL_INIT macros. * class.c (rb_include_class_new): Share WRAPPER between module and iclass, so serial can prevent double marking. * eval.c (rb_prepend_module): ditto. * eval.c (rb_using_refinement): ditto. * gc.c: Mark and free new wrapper struct. * gc.c (obj_memsize_of): Count size of additional wrapper struct. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43973 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
