From 79aeade6f6f8fbd7ce1da619fdd475e5db88ae24 Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Fri, 27 May 2011 20:18:26 +0100 Subject: [PATCH] ARM: disable ff_vector_fmul_vfp on VFPv3 systems This function uses old-style vector operations deprecated in VFPv3. Some implementations, e.g. Cortex-A9, support them only through slow software emulation. Cortex-A8 does have this functionality in hardware, but as it also has NEON, this function is not used there regardless.
