Test case
Dear Sir/Madam,
g++ 7.1.1 cannot compile correct OpenMP 4.5 code. I have attached a small
example program I initially developer to demonstrate a compiler bug for XLC.
GCC throws the following error message on compilation:
g++ -O2 -std=c++11 -fopenmp -foffload=nvptx-none -c aclass.cpp -o aclass.o
In file included from aclass.h:2:0,
from aclass.cpp:1:
masterclass.h: In member function 'void master::allocate(const unsigned int&)':
masterclass.h:10:50: error: 'master::data' is not a variable in 'map' clause
#pragma omp target enter data map(alloc: data[0:size*sizeof(double)])
^~~~
masterclass.h:10:9: error: '#pragma omp target enter data' must contain at
least one 'map' clause
#pragma omp target enter data map(alloc: data[0:size*sizeof(double)])
^~~
masterclass.h: In member function 'void master::deallocate()':
masterclass.h:15:51: error: 'master::data' is not a variable in 'map' clause
#pragma omp target exit data map(release: data[:0])
^~~~
masterclass.h:15:9: error: '#pragma omp target exit data' must contain at least
one 'map' clause
#pragma omp target exit data map(always, release: data[:0])
To me it seems that it cannot recognize the "alloc" clause.
Best Regards
Thorsten Kurth
