Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/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'. |
| yann@552 | 5 |
|
| yann@552 | 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. |
| yann@552 | 8 |
|
| yann@552 | 9 |
Here we restore the gcc-3.x behavior; the additional overhead of building all |
| yann@552 | 10 |
of these multilibs by default is negligible. |
