Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.0/gentoo/53_all_gcc4-superh-default-multilib.patch
|
yann@552
|
2 |
The gcc-3.x toolchains would contain all the targets by default. With gcc-4,
|
yann@552
|
3 |
you have to actually list out the multilibs you want or you will end up with
|
yann@552
|
4 |
just one when using targets like 'sh4-linux-gnu'.
|

|

|
6 |
The resulting toolchain can't even build a kernel as the kernel needs to build
|
yann@552
|
7 |
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
|
yann@552
|
10 |
of these multilibs by default is negligible.
