Speculative execution is a method to increase instruction level parallelism which can be exploited by both super-scalar and VLIW architectures. The key to a successful general speculation strategy is a repair mechanism to handle mispredicted branches and accurate reporting of exceptions for speculated instructions. Multiple instruction rollback is a technique developed for recovery from transient processor failures. This paper investigates the applicability of a recently developed compiler-assisted multiple instruction rollback scheme to aid in speculative execution repair. Extensions to the compiler-assisted scheme to support branch and exception repair are presented along with performance measurements across ten application programs. Our results indicate that techniques used in compiler-assisted rollback recovery are effective for handling branch and exception repair in support of speculative execution. |
