Bug ID: 106982
Summary: [OpenACC] ICE incorrect sharing of tree nodes with
nested reduction / .GOACC_REDUCTION
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, openacc
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: tschwinge at gcc dot gnu.org
Target Milestone: ---
ICE with gcc/g++ -fopenacc:
share10.i:6:9: error: incorrect sharing of tree nodes
6 | #pragma acc loop worker reduction(*:reduced)
| ^~~
MEM <double[5]> [(double *)&reduced]
MEM <double[5]> [(double *)&reduced] = .GOACC_REDUCTION (SETUP, 0, MEM
<double[5]> [(double *)&reduced], -1, 73, 0);
share10.i:6:9: error: incorrect sharing of tree nodes
----------- Failing code is -------------
int test1(double *c)
{
double reduced[5];
#pragma acc parallel loop gang private(reduced)
for (int x = 0; x < 5; ++x)
#pragma acc loop worker reduction(*:reduced)
for (int y = 0; y < 5; ++y) { }
}
