A word of warning. The -funroll-loops optimization CAN cause problems |
| 2 |
with GCC 3.0.x. I used to use all of the below optimizations myself, |
| 3 |
until I found -funroll-loops was more trouble than its worth (I had |
| 4 |
several programs I actively debugged, only to find it was an |
| 5 |
optimization error, and removing that particular optimization fixed the |
| 6 |
problem -- the code itself looked fine). |

Just a friendly note. I dont believe theres a problem with |
| 9 |
-funroll-loops on gcc 2.95.x. |
