Bug ID: 106492
Summary: ICE in #pragma omp for simd
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: sandra at gcc dot gnu.org
Target Milestone: ---
This is similar to PR106449; adding the simd keyword to an existing omp for
test case causes an ICE related to incompatible types.
Test case is derived from g++.dg/gomp/pr95063.C:
// PR c++/95063
template <typename T>
struct S {
T a : 12;
S () : a(0)
{
#pragma omp for simd linear(a)
for (int k = 0; k < 64; ++k)
a++;
}
};
struct U {
int a : 12;
U () : a(0)
{
#pragma omp for simd linear(a)
for (int k = 0; k < 64; ++k)
a++;
}
};
S<int> s;
U u;
