ABSTRACT:
In a computer system, programming code includes speculative code. The speculative code is code which is executed early based on speculation that the results from execution of the speculative code will be needed in the future. When executing instructions within a speculative sequence of code which includes memory accesses, any memory faults are ignored. When utilizing data generated during the speculative sequence of code a determination is made as to whether any memory fault occurred when the speculative sequence of code was executed. If it is determined that a memory fault occurred when the speculative sequence of code was executed, recovery code is generated which when executed performs a recovery from the memory fault.
