From a69da5c0ce3c932b310bca7cd5cce78961f9946b Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Sun, 6 Nov 2011 14:48:11 -0700 Subject: util: add log2f for Android MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is needed for nv50's new shader backend. With this change, both u_math.h and imports.h in core mesa define the same function. I have to #undef log2f here to avoid the conflict. Not sure if there is a better way to deal with the situation.
