No, not a duplicate.
Reduced a bit more:
struct builtin_simd
{
using type [[gnu::vector_size(sizeof(scalar_t) * length)]] = scalar_t;
};
struct simd_traits
{
using scalar_type = int;
template <typename X>
using rebind = typename X::type;
};
template <typename simd_t>
constexpr simd_t fill(typename simd_traits::scalar_type const scalar)
{
return simd_t{scalar};
}
using score_type = typename builtin_simd<int, 1>::type;
// Uncommenting this makes it work:
// const simd_traits::scalar_type n = 8;
score_type data[1]{fill<score_type>(8)};
The difference from uncommenting that line seems to be that then
free_lang_data_in_type is called for simd_traits::scalar_type. So the problem
seems to be that find_decls_types isn't finding scalar_type in the vector in
the array. So changing component to LTO and unassigning myself. Feel free to
change it back if it seems appropriate.
