preserve top-level named type during upcast to fusion type#6766
Merged
Conversation
Casting a value with a named type to a fusion type discards the name. Preseve it in the resulting fusion value instead. This change affects both upcast() and the fuse operator since it upcasts every value. This change does not affect the blend operator but I've added the same test cases to both runtime/ztests/op/blend.yaml and runtime/ztests/op/fuse.yaml to keep them in sync.
