--- Comment #2 from G. Steinmetz <gs...@t-online.de> ---
Hmm, trying to provide some reductions along different paths :
(iff there is no g++/gcc ICE, this PR can be closed then)
(will eventually retry with some future snapshots)
$ cat z1.C
void
foo (int *a)
{
#pragma omp parallel master default(none) private (k)
}
$ cat z2.C
void
foo (int *a)
{
int i, j, k, u = 0, v = 0, w = 0, x = 0, y = 0, z = 0;
z += a[i];
#pragma omp parallel master taskloop reduction (+:u) default(none)
firstprivate(a)
}
$ cat z3.C
void bar (int *);
void
foo (int *a)
{
int i, j, k, u = 0, v = 0, w = 0, x = 0, y = 0, z = 0;
{
z += a[i];
}
#pragma omp parallel master taskloop reduction (+:u) default(none)
firstprivate(a)
}
$ cat z4.C
void
foo (int *a)
{
int i, j, k, u = 0, v = 0, w = 0, x = 0, y = 0, z = 0;
{
for (i = 0; i < 64; i++)
for (i = 0; i < 64; ++i)
z += a[i];
}
#pragma omp parallel master taskloop reduction (+:u) default(none)
firstprivate(a)
}
Yields :
