ABSTRACT:
A compiler groups instructions into sets. The sets of instructions are related by data and control dependencies which are unresolvable by the compiler. Sets of instructions having unresolved dependencies are executed in a speculative state of the computer system under the assumption that an exception condition will not occur. However, if an exception condition does occur while executing a set of instructions in the speculative state, that exception condition is detected and the set of instructions is re-executed in a real state of the computer system to resolve the exception condition.
