Mapping the **this** pointer
Dear LLVM OpenMP 4.5 support.
I'm trying to map the **this** pointer of an class but I'm getting a
compilation error:
repro.cpp:20:38: error: expected expression containing only member accesses
and/or
array sections based on named variables
#pragma omp target enter data map(to:this)
^~~~
repro.cpp:27:41: error: expected expression containing only member accesses
and/or
array sections based on named variables
#pragma omp target exit data map(delete:this)
^~~~
2 errors generated.
I'm attaching a reproducible for the error.
# Compile
To compile: clang++ -fopenmp -fopenmp-targets=nvptx64-nvida-cuda repro.cpp
