Abstract: This paper presents a new version of instrumentation-based path profiling, implemented for the LCC compiler for Elbrus and SPARC processors. This profiling is intended to be used for VLIW-specific compiler optimizations, where path information and path correlations are needed. It was optimized, so profiling overhead descreased to 5.5 times on average.

Keywords: compiler; path profiling; profiling support library; VLIW.
