Spill all these virtual regs to memory TODO: see if we can split some of the live ranges instead of just globally spilling the virtual reg. TODO: On ciscy x86 and x86_64 we don't nessesarally have to add a mov instruction when making spills. If an instr is using a spilled virtual we may be able to address the spill slot directly. | |
