I would rather say that __PIC__ is guaranteed. |

Okay, this is why i wanted to know that from SPARC team, as I have no |
| 10 |
knowledge of that architecture. I suppose then that VIS cannot be handled by |
| 11 |
this way. |

Then you were wrong. I could have spent time explaining them when they make |
| 17 |
sense and why they don't in their usecases. If you did, well, then you really |
| 18 |
need to know better what you do because you seem to me pretty confused |
| 19 |
yourself, and I feel pity for you. |

Same arch, slightly different setup, I find simpler to change CFLAGS. |

Sorry I'm in the "Software engineering does not make real world usable" club. |
| 27 |
And find such terms opinable, subjective and vague. |

Point being? The idea would be that by default it passes the current |
| 31 |
GCC's -march. |

No it does not, as one would expect the big problems being hashed out first |
| 38 |
and then fine grained. But maybe I'm just a different kind of practical |
| 39 |
person than you are. Or you are not a practical person at all and just think |
| 40 |
of software engineering and theories and "this should work this way even if |
| 41 |
there is no real world way to make use of it".... oh wait... |
