Feedback-directed optimization is indicated by "+FDO", which means,
unless otherwise noted:
PASS1: -fb_create fbdata
PASS2: -fb_opt fbdata
Compiler: pathcc (PathScale C) unless otherwise noted.
If other compilers are used, they are indicated as:
g++ Gnu C++
pathCC PathScale C++
Integer base tuning:

Notes:
BIOS build A5S1, default setting was used.
Only one CPU was present in the system, other CPU was physically removed.
