| 4 | Subject: [PATCH] Enable SPE & AltiVec generation on powepc*linux target |
| 5 | |
| 6 | When is configured with --target=powerpc-linux, the resulting GCC will |
| 7 | not be able to generate code for SPE targets (e500v1/v2). |
| 8 | GCC configured with --target=powerpc-linuxspe will not be able to |
| 9 | generate AltiVec instructions (for e6500). |
| 10 | This patch modifies the configured file such that SPE or AltiVec code |
| 11 | can be generated when gcc is configured with --target=powerpc-linux. |
| 12 | The ABI and speciffic instructions can be selected through the |
| 13 | "-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters. |
| 14 | |
| 15 | Upstream-Status: Inappropriate [configuration] |
