* 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.
