Bug ID: 62092
Summary: libgomp.c++/target-2.C FAIL while compiling for OpenMP
4.0 offload target
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: iverbin at gmail dot com
To reproduce using trunk gcc:
g++ -fopenmp libgomp/testsuite/libgomp.c++/target-2.C
testsuite/libgomp.c++/target-2-aux.cc
GIMPLE after ompexp phase:
double fn2(...)
{
br.21_76 = &b; /* Ok. */
.omp_data_arr.33.br = &br;
__builtin_GOMP_target (-1, _Z3fn2iRA1024_dRPd._omp_fn.0, &__OPENMP_TARGET__,
22, &.omp_data_arr.33, &.omp_data_sizes.34, &.omp_data_kinds.35);
}
_Z3fn2iRA1024_dRPd._omp_fn.0 (struct .omp_data_t.30 * .omp_data_i)
{
__builtin_GOMP_parallel (_Z3fn2iRA1024_dRPd._omp_fn.1, &.omp_data_o.32, 0,
0);
}
_Z3fn2iRA1024_dRPd._omp_fn.1 (struct .omp_data_s.31 * .omp_data_i)
{
br.22_22 = &b; /* Error: trying to use global var b. */
}
