From e7fc353f044f9280222ca41b029b1368d2bf2fe3 Mon Sep 17 00:00:00 2001 From: Koichi Sasada Date: Mon, 4 Jan 2021 18:08:25 +0900 Subject: enable constant cache on ractors constant cache `IC` is accessed by non-atomic manner and there are thread-safety issues, so Ruby 3.0 disables to use const cache on non-main ractors. This patch enables it by introducing `imemo_constcache` and allocates it by every re-fill of const cache like `imemo_callcache`. [Bug #17510] Now `IC` only has one entry `IC::entry` and it points to `iseq_inline_constant_cache_entry`, managed by T_IMEMO object. `IC` is atomic data structure so `rb_mjit_before_vm_ic_update()` and `rb_mjit_after_vm_ic_update()` is not needed. --- debug_counter.h | 1 + 1 file changed, 1 insertion(+) (limited to 'debug_counter.h') diff --git a/debug_counter.h b/debug_counter.h index 8acca2741d..6dc66ef988 100644 --- a/debug_counter.h +++ b/debug_counter.h @@ -309,6 +309,7 @@ RB_DEBUG_COUNTER(obj_imemo_memo) RB_DEBUG_COUNTER(obj_imemo_parser_strterm) RB_DEBUG_COUNTER(obj_imemo_callinfo) RB_DEBUG_COUNTER(obj_imemo_callcache) +RB_DEBUG_COUNTER(obj_imemo_constcache) /* ar_table */ RB_DEBUG_COUNTER(artable_hint_hit) -- cgit v1.2.3
