This paper describes a compiler-based approach to provide multiple instruction rollback capability for general purpose processor registers. The objective is achieved by having the compiler remove all forms of N-instruction antidependencies. Pseudoregister antidependencies are removed by loop protection, node splitting, and loop expansion techniques; machine register antidependencies are prevented by introducing antidependency constraints in the interference graph used by the register allocator. To support separate compilation, inter-procedural antidependency constraints are added to the code generator to guarantee the termination of machine register antidependencies across procedure boundaries. The algorithms have been implemented in the IMPACT C compiler. Experiments illustrating the effectiveness of this approach are described |
