// Some registers were added on Adreno specifically and are not referenced in
// game .pdb files and never set by games.
// All unused bits are intentionally declared as named fields for stable
// comparisons when register values are constructed or modified by Xenia itself.
// Only 32-bit types (uint32_t, int32_t, float or enums with uint32_t / int32_t
// as the underlying type) are allowed in the bit fields here, as Visual C++
// restarts packing when a field requires different alignment than the previous
