Bug ID: 83844
Summary: [8 Regression] ICE with warn_if_not_aligned attribute
Product: gcc
Version: 7.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
typedef unsigned long long __u64
__attribute__((aligned(4),warn_if_not_aligned(8)));
void
bar (int n)
{
struct A
{
int i1;
int i2;
int i3[n];
__u64 x;
} __attribute__((aligned (8)));
struct B
{
int i1;
int i2;
long long i3[n];
__u64 x;
} __attribute__((aligned (8)));
struct A a;
struct B b;
}
ICEs starting with r251180. Obviously not in all structs we can use
tree_to_uhwi on DECL_FIELD_OFFSET without checking if it actually
tree_fits_uhwi_p.
