kkwli0 created this revision. This unit test fails on the system that has CUDA Toolkit 9.0 installed. And CUDA 9 does not support GPU arch sm_20. It results in the following error.
clang-6.0: error: GPU arch sm_20 is supported by CUDA versions between 7.0 and 8.0 (inclusive), but installation at /usr/local/cuda is 9.0. Use --cuda-path to specify a different CUDA install, pass a different GPU arch with --cuda-gpu-arch, or pass --no-cuda-version-check. https://reviews.llvm.org/D40996 Files: test/Driver/unknown-std.cpp Index: test/Driver/unknown-std.cpp =================================================================== --- test/Driver/unknown-std.cpp +++ test/Driver/unknown-std.cpp @@ -4,7 +4,7 @@ // RUN: not %clang %s -std=foobar -c 2>&1 | FileCheck --match-full-lines %s // RUN: not %clang -x objective-c++ %s -std=foobar -c 2>&1 | FileCheck --match-full-lines %s -// RUN: not %clang -x cuda -nocudainc -nocudalib %s -std=foobar -c 2>&1 | FileCheck --match-full-lines --check-prefix=CHECK --check-prefix=CUDA %s +// RUN: not %clang -x cuda -nocudainc -nocudalib --no-cuda-version-check %s -std=foobar -c 2>&1 | FileCheck --match-full-lines --check-prefix=CHECK --check-prefix=CUDA %s // CHECK: error: invalid value 'foobar' in '-std=foobar' // CHECK-NEXT: note: use 'c++98' or 'c++03' for 'ISO C++ 1998 with amendments' standard
