Building on #76615 (#46593) by @Destroyerrrocket - we don't currently support accessing vector elements in constant expressions:
```cpp
typedef int __v4si __attribute__((__vector_size__(16)));
constexpr int extract0(__v4si v) {
return v[0];
}
constexpr __v4si insert(__v4si v, int i, int s) {
v[i] = s;
return v;
}
```
https://gcc.godbolt.org/z/zfKs5EjWc has more examples (non-constant element indices, implicit conversions etc.)
