Module: libav Branch: master Commit: 6eda85e15b38863a627fd0602098aa3250174698
Author: Reimar Döffinger <[email protected]> Committer: Ronald S. Bultje <[email protected]> Date: Wed Mar 7 21:35:13 2012 +0100 sbrdsp.asm: convert all instructions to float/SSE ones. Since the values are floats, using the float operations makes sense, improves performance on some CPUs and makes the code SSE compatible instead of needing SSE2. Based on suggestion by Jason.
