clang version 13.0.0
FreeBSD 13.0-RELEASE
powerpc64le
Reduced test case:
```
float a[4096];
template <int b> struct d {
enum { c = 1 << b } ak[c];
void g();
};
int e;
void h(d<17>, int);
void i() {
d<2> b;
d<17> c;
for (int f = 0; f < 4096; f++)
a[f] = f;
b.g();
for (int f = 0; f < 4096; f++)
a[f] = f;
for (int f = 0; f < 4096; f++)
a[f] = f * 4096;
h(c, e);
}
```
Compile with:
`clang++13 -cc1 -triple powerpc64le-unknown-freebsd13.0 -emit-obj -target-cpu ppc64le -O2 -vectorize-loops organ-5b291c.cpp`
The issue doesn't happen after removing `-vectorize-loops` or after replacing `-O2` with `-O1`.
