Do I understand this correctly? |
12 |
|

Up until now, gcc implicitly assumed -march=i386 if nothing else |
14 |
was specified by the user. |
15 |
|
16 |
Now, it defaults to something different, so -mtune works |
17 |
differently than it used to. |

If both are correct, I have questions? |

|
21 |
- With what version did/will gcc change? |
22 |
Corollary: In what Changelog of gcc can I find out more? |
23 |
(Rather: which changelog can I point my coworkers to) |
24 |
- What's the new default? |

Thanks, |
