Add support for the Signal Processing Engine. This will set up |
| yann@1634 | 32 |
the toolchain so that it supports the SPE ABI extensions. This |
| yann@1634 | 33 |
mainly targets Freescale e500 processors. |

Setting this option will append "spe" to the end of your target |
| yann@1634 | 36 |
tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc |
| yann@2467 | 37 |
configure/build system will know to include SPE ABI support. It |
| yann@2467 | 38 |
will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS, |
| yann@2467 | 39 |
and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you |
| yann@2467 | 40 |
do not need to explicitly add them. |
