After doing my periodical emerge update, I notice that gcc-4.5.1 is |
| 2 |
now unmasked and presumably stable. I also notice that a couple of |
| 3 |
new options are possible with this new release, namely Graphite and |
| 4 |
FLTO optimizations. (Actually, Graphite has been available for a while |
| 5 |
but I haven't been following gcc development too closely and only now |
| 6 |
do I become aware of it.) |

Does anyone have any comments on the use of Graphite and/or FLTO? |
| 9 |
Are they capable of significant improvements on a amd64 system? |

|
| 11 |
Supposedly FLTO will greatly increase file size and thus could be |
| 12 |
selectively enabled for only a few packages. Would building gcc |
| 13 |
itself with FLTO be advisable? |
| 14 |
|
| 15 |
There are reports that many packages fail to build with FLTO: |

Since I have encountered little detailed discussion on this topic, |

I am posting my question to this list. |
