From b280c6202b28b371a8d96850194fd69d7ad5dcc0 Mon Sep 17 00:00:00 2001 From: Martin Storsjö Date: Sun, 16 Nov 2014 12:46:51 +0200 Subject: arm: fft_vfp: Unify the behaviour in ff_fft_calc_vfp between arm/thumb MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Don't include the function pointer table in the code segment in arm mode. This shouldn't have any significant performance effect. It does end up as a few more instructions than before, for ARM, but only at the entry to this function, not within the fft functions themselves.
