[Clang] [NFC] fix CHECK lines for convergent attribute tests
2021-06-28 16:13:02 +08:00
// RUN: %clang_cc1 -triple i386-pc-win32 -emit-llvm -fconvergent-functions -o - < %s | FileCheck -check-prefixes=CHECK,CONVFUNC %s
// RUN: %clang_cc1 -triple i386-pc-win32 -emit-llvm -o - < %s | FileCheck -check-prefixes=CHECK,NOCONVFUNC %s
clang: Add -fconvergent-functions flag The CUDA builtin library is apparently compiled in C++ mode, so the assumption of convergent needs to be made in a typically non-SPMD language. The functions in the library should still be assumed convergent. Currently they are not, which is potentially incorrect and this happens to work after the library is linked.
