OK, r46811 (I also made trivial commit r46813 to shrink catch entry) What should we do about rb_iseq_build_for_ruby2cext? I think it is broken, now (as is anything else which might depend on iseq internals). ---------------------------------------- Feature #10030: [PATCH] reduce rb_iseq_struct to 296 bytes https://bugs.ruby-lang.org/issues/10030#change-47758 * Author: Eric Wong * Status: Open * Priority: Low * Assignee: Koichi Sasada * Category: core * Target version: current: 2.2.0 ---------------------------------------- This probably breaks ruby2cext; but I'm not sure if anybody uses that. May we remove rb_iseq_build_for_ruby2cext? I will probably have more patches along these lines to reduce iseq-related allocations. This is probably the most obvious, aside from ruby2cext compatibility. Most iseq do not have a catch_table, so avoid needlessly adding 4-8 bytes to the struct for the common case. * iseq.h (struct iseq_catch_table): new flexible array struct (iseq_catch_table_each): new iterator macro (iseq_catch_table_bytes): new size macro * vm_core.h (struct rb_iseq_struct): use _catch_table member * compile.c (iseq_set_exception_table): update for struct changes * iseq.c (iseq_free): ditto * iseq.c (iseq_memsize): ditto * iseq.c (rb_iseq_disasm): ditto * iseq.c (iseq_data_to_ary): ditto * iseq.c (rb_iseq_build_for_ruby2cext): ditto (untested) * vm.c (vm_exec): ditto * vm_core.h (struct rb_iseq_struct): ditto * vm_insnhelper.c (vm_throw): ditto ---Files-------------------------------- iseq_catch_table_flex.patch (8.94 KB) iseq_catch_table_flex_v2.patch (8.72 KB) iseq_catch_table_flex_v3.patch (9.05 KB) -- https://bugs.ruby-lang.org/
