toolchain.eclass: mangle -O3 down to -O2, not -O0 |
| 9 |
|
| 10 |
In bug #701786 'strip-flags' removed all unsafe options |
| 11 |
first including -O3 and only then mangled -O? to -O2. |
| 12 |
|
| 13 |
This effectively made gcc to compalie wth -O0, generated |
| 14 |
huge slow profile and confused LTO. |
| 15 |
|
| 16 |
Let's default to safer -O3->-O2 transition. |
