* Ref types workingCliff Click2024-08-0625-149/+273
| | | | | | | | | GCM uses a breadth-first pass for schedule-late instead of a post-order; the post-order walk depends on StoreNodes being pinned, which is true in C2 but not Simple. Move GCM call out of IterPeeps. Struct field init is "makeInit()" not integer zero. Rename Type._print to print. Store,Load prints include field name.

| | | | | | | | | | | | | | | | | | | | | | | * Missing idepth for LoopNode * backedge code removing a Parser keep Stop subsuming a node parser yet needs * Missing addDep * LoadNode cloning peep better profit The LoadNode cloning peep cannot clone around a Loop unless its profit on the backedge, otherwise might infinitely clone around backedge. peep: x - (-y) is x+y peep: -(-x) is x * Drop alias from Field Field is intended to be a part of a Type; as such is abstract, immutable, and true for ALL Time and all TypeStructs which have the same field. Drop the alias and struct from Field. Drop field reset. The alias#s are decided in the Parser, and have a lifetime for the compilation unit; the Fields have infinite lifetime.
