The 2 above are GCC 4 specific and only valid with the new binutils. You |
| 18 |
also have to obtain a custom ebuild to turn these options on in |
| 19 |
GCC/glibc. I don't remember what I did any more. Also not sure where I |
| 20 |
got the information on these from, this was some time ago, but try |
| 21 |
Google. See gentoo-wiki to start off with. |

As Mike A. says in response to another message - |

| 25 |
It's the mindless optimisation, that will eventually break a package, that |
| 26 |
gives Gentoo a very bad name, and which is why many creators of packages hate |
| 27 |
us. |

I have to concur here and recommend that one always do the necessary |
| 30 |
research on the flags and what they mean. Many of the flags may actually |
| 31 |
slow the system down. Or even have unwanted side effects. -Bdirect is a |
| 32 |
good example. It's why I try and keep my flags to a minimum. |
| 33 |

BTW, I intended to run Xen on my system, that's why I have |
| 35 |
-mno-tls-direct-seg-refs in there. |
