Conditional branches incur a severe performance penalty in wide-issue, deeply pipelined processors. Speculative execution(1, 2) and predicated execution(3---9) are two mechanisms that have been proposed for reducing this penalty. Speculative executio

To effectively exploit instruction level parallelism, the compiler must move instructions across branches. When an instruction is moved above a branch that it is control dependent on, it is considered to be speculatively executed since it is executed

Superscalar and superpipelined processors utilize parallelism to achieve peak performance that can be several times higher than that of conventional scalar processors. In order for this potential to be translated into the speedup of real program, the

A compiler for VLIW and superscalar processors must expose sufficient instruction-level parallelism (ILP) to effectively utilize the parallel hardware. However, ILP within basic blocks is extremely limited for control-intensive programs. We have deve

SUMMARY This paper describes critical implementation issues that must be addressed to develop a fully automatic inliner. These issues are: integration into a compiler, program representation, hazard prevention, expansion sequence control, and program

This paper describes the design and implementation of an optimizing compiler that automatically generates profile information to assist classic code optimizations. This compiler contains two new components, an execution profiler and a profile-based c

Microcode optimization techniques such as code scheduling and resource allocation can benefit significantly by reducing uncertainties in program control flow. A trace selection algorithm with profiling information reduces the uncertainties in program
