No. See my posts in the other part of this thread where threading was |
14 |
once broken by a stupid mobile phone MUA. |

Every "native" setting is just resolved by gcc at compile time to some |
17 |
concrete setting like "core2". There is nothing magical about it and you |
18 |
also don't need to recompile glibc or gcc any more than you need after |
19 |
switching your march settings between two other settings. |

No one had any breakage during the time when -march=core2 was introduced |
22 |
and all Core2 owners switched from -march=nocona to -march=core2. There |
23 |
should be no more breakage when switching to "native". |

Correlation does not imply causation. |
