From 2881c83127c680defd1d596200897dd6b6db7977 Mon Sep 17 00:00:00 2001 From: Måns Rullgård Date: Sat, 20 Mar 2010 21:27:03 +0000 Subject: Call rdft by function pointer Call the RDFT by a function pointer like other FFT related transforms. This makes instruction set optimized versions possible. Based on patch by Alex Converse.
