Abstract
A method of register allocation in complier using a computer instruction set having tiered instructions that accesses differing numbers of registers makes a first preliminary register allocation attempt using an initially specified register set for each instruction. If this fails, the method identifies instructions having an initially specified limited register having a variable not register allocatable. The method makes a second preliminary register allocation attempt except using a less restrictive register set for the identified instructions. This method employs a next less restrictive register set and re-attempts preliminary register allocations for instructions with more than two levels of register restriction.
