+Subject: [PATCH 29/46] 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]
