Your cflags really aren't going to change much. It's better to stick |
| 7 |
with something that's been tested by a large number of people and is |
| 8 |
known to be safe. For instance, consider the 3rd post in this forum |
| 9 |
thread [1]. Even with an application like povray which is highly math |
| 10 |
and CPU driven tossing in all kinds of crazy cflags only results in a |
| 11 |
maximum of 0.05s (1.7%) improvement over the baseline -O2 -march |
| 12 |
settings, and that sort of difference in times is almost certainly |
| 13 |
within the margin of error. Most of the cflags (including -O3) |
| 14 |
actually decreased performance. |
