I would like to revisit this. Do we need this many call to malloc_usable_size()? ---------------------------------------- Feature #10238: todo: remove dependency on malloc_usable_size https://bugs.ruby-lang.org/issues/10238#change-81512 * Author: normalperson (Eric Wong) * Status: Open * Priority: Normal * Assignee: * Target version: Next Major ---------------------------------------- malloc_usable_size shows up at or near the top of many profiles for me. We should be able to use ruby_sized_xfree in more places; especially if rb_data_type_t->dsize is defined. One possible improvement is to allow the rb_data_type_t->dsize pointer to be a FIXNUM, removing the need for some memsize functions. Furthermore, over-accounting malloc-ed bytes (presumably the reason malloc_usable_size was introduced). should be less harmful nowadays with incremental marking. ---Files-------------------------------- 0001-gc.c-use-ruby_sized_xfree-in-more-places.patch (3.19 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
