From 14f68c3965a2ceb64228341bb5769155b1eb2e13 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 11 Nov 2014 05:11:09 +0000 Subject: [PATCH] Add illegal cilk checks to C++ front. Add calls for several illegal Cilk cases to the C++ frontend. C++ usually doesn't ICE unlike C on illegal cilk, but it's better to match C in what is allowed and what is not. if (_Cilk_spawn ...) is still not errored, but at least it doesn't ICE. gcc/cp/: 2014-11-10 Andi Kleen * semantics.c (finish_goto_stmt): Call check_no_cilk. (finish_while_stmt_cond): Dito. (finish_do_stmt): Dito. (finish_for_cond): Dito. (finish_switch_cond): Dito.
