Summary: ICE using _Cilk_spawn without -fcilkplus
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following valid code snippet (compiled *without* "-fcilkplus")
triggers an ICE on trunk:
==============================================================
void foo()
{
_Cilk_spawn foo();
}
==============================================================
bug.cc: In function 'void foo()':
bug.cc:3:20: internal compiler error: in cp_gimplify_expr, at
cp/cp-gimplify.c:714
_Cilk_spawn foo();

Balaji, this appeared right after your patch
2013-12-11 Balaji V. Iyer <balaji.v.i...@intel.com>
* cp-tree.h (cilk_valid_spawn): New prototype.
(gimplify_cilk_spawn): Likewise.
(create_try_catch_expr): Likewise.
* decl.c (finish_function): Insert Cilk function-calls when a
_Cilk_spawn is used in a function.
* parser.c (cp_parser_postfix_expression): Added RID_CILK_SPAWN and
RID_CILK_SYNC cases.
[...]
Would you mind havin a look?
