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. --- internal/imemo.h | 1 + 1 file changed, 1 insertion(+) (limited to 'internal') diff --git a/internal/imemo.h b/internal/imemo.h index d10f89cb86..a9e2136ac4 100644 --- a/internal/imemo.h +++ b/internal/imemo.h @@ -45,6 +45,7 @@ enum imemo_type { imemo_parser_strterm = 10, imemo_callinfo = 11, imemo_callcache = 12, + imemo_constcache = 13, }; /* CREF (Class REFerence) is defined in method.h */ -- cgit v1.2.3
