Bug ID: 81896 Summary: omp target enter data not recognized Product: gcc Version: 7.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: thorstenkurth at me dot com Target Milestone: --- Created attachment 42005 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42005&action=edit small test case Dear Sir/Madam, I am not sure if my report got posted the first time because I cannot find it any more (did not receive a notification about it and it is also not marked invalid somewhere). Therefore, I will post it again. It seems that gcc has problems with the omp target enter/exit data constructs. When I compile the appended code I get: 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(release: data[:0]) ^~~ make: *** [aclass.o] Error 1 The same code compiles fine when using XLC.
