noduplicate has different semantics than convergent. Although it is proposed for SPMD originally, it could be used by non-SPMD programs to forbid duplicate of functions. There may be applications using this attribute. I would suggest to leave this question for future. Probably ask llvm-dev first since the attribute is also in LLVM. ================ Comment at: include/clang/Basic/AttrDocs.td:630 + void convfunc(void) __attribute__((convergent)); + // Setting it as a C++11 attribute is also valid in a C++ program. + // void convfunc(void) [[clang::convergent]]; ---------------- Anastasia wrote: > Did you mean "in an OpenCL program"? No. In C++ program only, it is also valid to set it as C++11 attribute. OpenCL does not support C++11 attribute. https://reviews.llvm.org/D25343 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
