RPG^2 is a pure-software system that operates on running C/C++ programs, profiling them, injecting prefetch instructions, and then tuning those prefetches to maximize performance.

This is from an email I received:
The bolt pass failed run. For the nas-is and nas-cg, it shows operand is not an expression. For hash join, bfs, g500, pr, it shows TopLLCMiss is not a loop.I attached the nas-is backtrace. I wonder if I need to modify the code. Thanks for your help!
