Hello Jason et al., Mike Stump mentioned that my _Cilk_spawn and _Cilk_sync for C++ may have been lost in the email pile. So, attached is an updated _Cilk_spawn and _Cilk_sync for C++ patch. Is this Ok to install? Here are the ChangeLog entries (they shouldn't have changed since the last submission): gcc/cp/ChangeLog 2013-11-17 Balaji V. Iyer <balaji.v.iyer@intel.com> * Make-lang.in (CXX_AND_OBJCXX_OBJS): Added cp/cp-cilk.o. * cp-cilk.c: New file. * cp-tree.h (cilk_valid_spawn): New prototype. (gimplify_cilk_spawn): Likewise. (cp_cilk_install_body_wframe_cleanup): Likewise. (cilk_create_lambda_fn_tmp_var): Likewise. * decl.c (finish_function): Insert Cilk function-calls when a _Cilk_spawn is used in a function. * except.c (do_begin_catch): Made the function non-static. (do_end_catch): Likewise. * parser.c (cp_parser_postfix_expression): Added RID_CILK_SPAWN and RID_CILK_SYNC cases. * parser.h (IN_CILK_SPAWN): New #define. * cp-objcp-common.h (LANG_HOOKS_CILKPLUS_GIMPLIFY_SPAWN): Likewise. (LANG_HOOKS_CILKPLUS_DETECT_SPAWN_AND_UNWRAP): Likewise. (LANG_HOOKS_CILKPLUS_FRAME_CLEANUP): Likewise. * pt.c (tsubst_expr): Added CILK_SPAWN_STMT and CILK_SYNC_STMT cases. * semantics.c (potential_constant_expression_1): Likewise. (finish_call_expr): Stored the lambda function to a variable when Cilk Plus is enabled. * typeck.c (cp_build_compound_expr): Reject a spawned function in a compound expression. (check_return_expr): Reject a spawned function in a return expression. gcc/testsuite/ChangeLog 2013-11-17 Balaji V. Iyer <balaji.v.iyer@intel.com> * g++.dg/cilk-plus/CK/catch_exc.cc: New test case. * g++.dg/cilk-plus/CK/const_spawn.cc: Likewise. * g++.dg/cilk-plus/CK/fib-opr-overload.cc: Likewise. * g++.dg/cilk-plus/CK/fib-tplt.cc: Likewise. * g++.dg/cilk-plus/CK/lambda_spawns.cc: Likewise. * g++.dg/cilk-plus/CK/lambda_spawns_tplt.cc: Likewise. * g++.dg/cilk-plus/cilk-plus.exp: Added support to run Cilk Keywords test stored in c-c++-common. Also, added the Cilk runtime's library to the ld_library_path. Thanks, Balaji V. Iyer.j
