From 603221ebd03348c2cabe9516c60bb6ef183a3880 Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Mon, 13 Aug 2012 15:18:47 +0200 Subject: [PATCH] g723_1dec: inline normalize_bits() in scale vector and optimize it. many branches and cases of scale_vector are irrelevant for the case here and by inlining they can be reliably removed.
