| Subject: [PATCH 30/35] Enable SPE & AltiVec generation on powepc*linux target |
| |
| When is configured with --target=powerpc-linux, the resulting GCC will |
| not be able to generate code for SPE targets (e500v1/v2). |
| GCC configured with --target=powerpc-linuxspe will not be able to |
| generate AltiVec instructions (for e6500). |
| This patch modifies the configured file such that SPE or AltiVec code |
| can be generated when gcc is configured with --target=powerpc-linux. |
| The ABI and speciffic instructions can be selected through the |
| "-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters. |
| |
| Upstream-Status: Inappropriate [configuration] |
