Alexey,
Am still seeing a build time error like below:
$ clang++ -g -fopenmp -fopenmp-targets=nvptx64 new.cpp
nvlink error : Undefined reference to '_Znam' in '/tmp/new-a4b234.cubin'
clang-11: error: nvlink command failed with exit code 255 (use -v to see
invocation)
$ cat new.cpp
int main() {
#pragma omp target parallel for
for (int i=0;i<10;i++) {
int *a = new int[100];
}
}
Are you still working on this? My Clang(-11) is the latest one built from
Trunk.
