For compute shaders, to avoid a crash with that optimization, it requires
doing some optimizations and lowerings before. Example:
static void
lower_cs_shared(struct nir_shader *nir)
{
NIR_PASS_V(nir, nir_lower_vars_to_explicit_types,
nir_var_mem_shared, shared_type_info);
NIR_PASS_V(nir, nir_lower_explicit_io,
nir_var_mem_shared, nir_address_format_32bit_offset);
}
In the same way other drivers (like anv) calls
nir_opt_load_store_vectorize as part of their post-process-nir.
So one option would be to move nir_opt_load_store_vectorize outsize
the common v3d_nir_optimize, to a post-process nir method.
To make things simpler, this change calls that optimization only if we
have a v3d_compiler object, that is when each frontend has already
done their lowerings, and call the v3d_compiler to get the final
assembly (so we are already on a kind of post processing nir step).
This avoids dEQP-VK.memory_model.shared.basic_types.3 crashing if we
start to call v3d_optimize_nir on v3dv directly.
Slight shaderdb changes, but not significant.
