to bart: i believe they refer to -O2 being faster COMPILE, as -O3 is |
27 |
higher optimization for speed and larger code size and longer compile |
28 |
time etc. There are some fine tunings you can do to make the most out |
29 |
of your time and space in all areas. check out the gcc documentation on |
30 |
options that control optimization. For instance, specifying what kinds |
31 |
of functions to inline. |

to erik: i thought 7.1 does not use objprelink? it wasnt exactly stable... |
