4Subject: [PATCH 29/46] Enable SPE & AltiVec generation on powepc*linux target
5
6When is configured with --target=powerpc-linux, the resulting GCC will
7not be able to generate code for SPE targets (e500v1/v2).
8GCC configured with --target=powerpc-linuxspe will not be able to
9generate AltiVec instructions (for e6500).
10This patch modifies the configured file such that SPE or AltiVec code
11can be generated when gcc is configured with --target=powerpc-linux.
12The ABI and speciffic instructions can be selected through the
13"-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters.

15Upstream-Status: Inappropriate [configuration]
