Bug ID: 67521
Summary: ICE when OpenMP loop expressions mention the IV
Product: gcc
Version: 5.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
void
foo (int j)
{
int i = 0;
#pragma omp parallel for simd
for (i = (i & j); i < 10; i = i + 2)
;
i = 0;
#pragma omp parallel for simd
for (i = 0; i < (i & j) + 10; i = i + 2)
;
i = 0;
#pragma omp parallel for simd
for (i = 0; i < 10; i = i + ((i & j) + 2))
;
}
ICEs, because the iterator is mentioned in the expressions. Note if called
with
j = 0 supposedly the expressions should be still loop invariant.
