Please don't include "unset CFLAGS" in your ebuilds. This will cause all |
| 2 |
sorts of nastiness to happen. For example, you'll end up generating v7 |
| 3 |
code for v9 SPARCs, which involves massive amounts of kernel emulation |
| 4 |
and so is reaaaallly slow, and you'll utterly b0rk anything system which |
| 5 |
needs ABI options included in CFLAGS. |
| 6 |
|
| 7 |
Similarly, don't ignore user CFLAGS. I don't care whether your upstream |
| 8 |
wants everyone to use -ffast-math, especially if they're forcing us to |
| 9 |
run v7 FP code emulated on a v9 CPU. Or big endian code on a little |
| 10 |
endian CPU. aceB,esu ay wonkht ,s'tasuj on tog t annkrow... |

Use flag-o-matic's strip-flags instead. It's not perfect, but it's far |
| 13 |
less likely to break things. When it *does* break things, we can usually |
| 14 |
fix it globally rather than having to sed the whole tree. |

Oh, yeah, I know some bootloaders probably have to do fancy stuff. |
| 17 |
They're excluded :) |

This rant brought to you by the "one of vim7's new deps does this and so |
| 20 |
will probably have to be USE.mask'ed on most archs" department. |
