From 2c05b4072f982df8002d61327837e18a724e934f Mon Sep 17 00:00:00 2001 From: Alexandru-Cezar Sardan Date: Wed, 5 Feb 2014 16:52:31 +0200 Subject: [PATCH 28/47] 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.
