LOCAL foilset Optimizing Java

Based on Summer work by Zoran Budimlic at JavaSoft and Collaboration with Ken Kennedy

Java bytecodes are at a higher level than ordinary assembly code

Exceptions greatly reduce code movement opportunities

OOP style (lots of method calls) reduces the data flow information available

No knowledge about the whole program at compile time

Standard trilema: functionality vs. portability vs. performance

Adopt the current javac strategy: one class at a time, no changes to VM, lowest performance

Or sacrifice some portability and functionality for better optimization

Or sacrifice a lot of portability and functionality for best performance
