Bug ID: 90811 Summary: [nvptx] ptxas error on OpenMP offloaded code Product: gcc Version: 9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: jakub at gcc dot gnu.org Target Milestone: --- The following testcase doesn't assemble when using CUDA ptxas (or fails at runtime due to the PTX assembly not being valid) with -O2 -fopenmp: int main () { long long a[100], b[100]; int i; for (i = 0; i < 100; i++) { a[i] = i; b[i] = i % 10; } #pragma omp target teams distribute parallel for simd map(tofrom: a[:100], b[:100]) for (i = 0; i < 100; i++) { long long c = 0; const long long d[] = { 1, 3, 5, 7, 9 }; for (int j = 4; j >= 0; j--) c = d[j] + b[i] * c; a[i] += c; } for (i = 0; i < 100; i++) { const long long r[] = { 1, 26, 229, 976, 2849, 6646, 13381, 24284, 40801, 64594 }; if (a[i] != r[i % 10] + (i / 10 * 10)) __builtin_abort (); } return 0; }
