I haven't been able to use Gentoo directly, but I have used Linux on |
| 9 |
Power on GCC's servers. There's nothing terribly abnormal, though |
| 10 |
there's a lot of interesting FPU modes. |

You should use ppc64le. This complicates things when compiling, and is |
| 18 |
a minor issue for some other compilers, who do not support multilib in |
| 19 |
a way that makes it possible to build a ppc64le toolchain from a ppc64 |
| 20 |
toolchain. You may need to set up tools on a computer of another |
| 21 |
architecture, or get prebuilt tools from GCC. |

They are expensive, but one day, if the Lord decides to bless me, I may own one. |
