From 38bab3635ac79d6d6fb1468713f092eda8d9ca7f Mon Sep 17 00:00:00 2001 From: Sven Neumann Date: Wed, 5 Feb 2014 09:14:39 +0100 Subject: [PATCH] opus: allow to select fixed-point implementation The default of choosing the fixed-point implementation if the target hardware does not have floating-point unit is not always the best choice. Modern ARM hardware has floating point support but most likely the fixed-point implementation in Opus will still perform better. In particular if your CPU supports the NEON extension. This commit allows to select the fixed-point implementation manually and sets the default based on the availability of a floating-point unit.
