From 4ed8c1fd9dc05f7a9db9298a55396c8f0ff549a7 Mon Sep 17 00:00:00 2001 From: Alexandru-Cezar Sardan Date: Wed, 5 Feb 2014 16:52:31 +0200 Subject: [PATCH 30/46] 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.
