From c0085f94fea89b180e5727b193484a83586d3490 Mon Sep 17 00:00:00 2001 From: Derek Buitenhuis Date: Tue, 15 Jan 2013 16:09:01 -0500 Subject: [PATCH] mpegaudio_tablegen: Don't use llrint You cannot count on it being present on all systems, and you cannot include libm.h in a host tool, so just hard code a baseline implementation.
