Bug ID: 100902
Summary: pointer attachment issues
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
On:
void
foo (int *ptr)
{
#pragma omp target map (ptr, ptr[:4])
#pragma omp parallel master
ptr[0] = 1;
}
void
bar (int *ptr)
{
#pragma omp target parallel map (ptr[:4], ptr)
#pragma omp master
ptr[0] = 1;
}
foo is compiled fine, but bar ICEs because c_omp_adjust_map_clauses isn't
called
on the combined constructs.
Another bug is that
void
baz (int *ptr)
{
#pragma omp target map (ptr[:4], ptr)
#pragma omp parallel master
ptr[0] = 1;
}
void
qux (int *ptr)
{
#pragma omp target parallel map (ptr, ptr[:4])
#pragma omp master
ptr[0] = 1;
}
is rejected by both C and C++ pointers twice with
‘ptr’ appears both in data and map clauses
The user ordering of clauses (which is reversed for the non-combined cases in
the implementation) should not matter.
I'll deal with the bar issue for now.
