AOCC for the most part is very competitive with GCC 8.2 and only in a few cases was it generating slower code than upstream Clang.

Build times with AOCC is much slower, which is to be expected considering AOCC has more optimization passes that are run in an effort to generate faster compiled code.

The AOCC 1.3 performance was looking good with the Bullet Physics Library.
