Add support for the Signal Processing Engine. This will set up |
| yann@1181 | 11 |
the toolchain so that it supports the SPE ABI extensions. This |
| yann@1181 | 12 |
mainly targets Freescale e500 processors. |

Setting this option will append "spe" to the end of your target |
| yann@1181 | 15 |
tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc |
| yann@1181 | 16 |
configure/build system will know to include SPE ABI support. |
| yann@1181 | 17 |
It will also automatically add "-mabi=spe -mspe" to your |
| yann@1181 | 18 |
TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG, |
| yann@1181 | 19 |
so you do not need to explicitly add them. |
