From 2209e152c0ec2c0548c22b2b14e52007b74a9efb Mon Sep 17 00:00:00 2001 From: Takashi Kokubun Date: Mon, 31 May 2021 21:57:56 -0700 Subject: [PATCH] Decompose the captured_cc code for investigation I'm investigating SEGVs like https://github.com/ruby/ruby/runs/2715166621?check_suite_focus=true. Because a lot of things are going on on this line, it's hard to identify the cause, especially because we can't get the core file of the failures. Therefore I intentionally increased the number of lines for investigation. --- tool/ruby_vm/views/_mjit_compile_send.erb | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/tool/ruby_vm/views/_mjit_compile_send.erb b/tool/ruby_vm/views/_mjit_compile_send.erb index d1540f69bb..28e316a1ef 100644 --- a/tool/ruby_vm/views/_mjit_compile_send.erb +++ b/tool/ruby_vm/views/_mjit_compile_send.erb @@ -13,7 +13,9 @@ MAYBE_UNUSED(<%= ope.fetch(:decl) %>) = (<%= ope.fetch(:type) %>)operands[<%= i %>]; % end % # compiler: Use captured cc to avoid race condition - const struct rb_callcache *captured_cc = captured_cc_entries(status)[call_data_index(cd, body)]; + size_t cd_index = call_data_index(cd, body); + const struct rb_callcache **cc_entries = captured_cc_entries(status); + const struct rb_callcache *captured_cc = cc_entries[cd_index]; % % # compiler: Inline send insn where some supported fastpath is used. const rb_iseq_t *iseq = NULL;
