Inter-procedural allocation of stacked registers for a processor

摘要

A method for an allocation of stacked registers for Intel's Itanium(R) processor includes a three step process. Step I determines an intra-procedural stacked register usage by a program having a plurality of procedures. In step II, the disclosed method performs an inter-procedural analysis to assign quota of stacked register usage to every procedure. In step III, each procedure is allocated stacked register usage based on the quota assignments of step II.
