Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch
|
|
yann@552
|
2 |
Set the default behavior on alpha to use -mieee since the large majority of
|
|
yann@552
|
3 |
time we want this (bad/weird things can happen with packages built without
|
|
yann@552
|
4 |
-mieee).
|
|
yann@552
|
5 |
|
|
yann@552
|
6 |
To satisfy those people who may not want -mieee forced on them all the time,
|
|
yann@552
|
7 |
we also provide -mno-ieee.
