ABSTRACT	Profiling is a technique of gathering program statistics in order to aid program optimization. In particular, it is an essential component of compiler optimization for the extraction of instruction--level parallelism. Code instrumentation has been the most popular method of profiling. However, real-time, interactive, and transaction processing applications suffer from the high execution-time overhead imposed by software instrumentation. This paper suggests the use of hardware dedicated to the task of profiling. The hardware proposed consists of a set of counters, the profile buffer. A profile collection method that combines the use of hardware, the compiler and operating system support is described. Three methods for profile buffer indexing, address-mapping, selective indexing, and compiler indexing are presented that allow this approach to produce accurate profiling information with very little execution slowdown. The profile information obtained is applied to a prominent compiler opt...	user correction - Legacy Corrections
