From 0c012e9bf7a7c16283091714f18f8aa3633d89b6 Mon Sep 17 00:00:00 2001 From: Richard Earnshaw Date: Wed, 16 Nov 2016 14:02:10 +0000 Subject: [PATCH] [arm] Add vfpv2 and neon-vfpv3 * arm/arm-fpus.def (vfpv2): New FPU, currently an alias for 'vfp'. (neon-vfpv3): New FPU, currently an alias for 'neon'. * arm/arm-tables.opt: Regenerated. * arm/t-aprofile (MULTILIB_REUSE): Add reuse rules for vfpv2 and neon-vfpv3. * doc/invoke.texi (ARM: -mfpu): Document new options. Note that 'vfp' and 'neon' are aliases for specific implementations.
