This is an automated email from the git hooks/post-receive script.
trondeau pushed a commit to branch android
in repository gnuradio.
commit 86d29d2e8ddccdf1710f94229e4493a97fce0ca6
Author: Tom Rondeau <address@hidden>
Date: Sun Dec 21 10:43:20 2014 -0500
volk: using hypot instead of cabsf.
Android (API 21) does not support cabsf (known bug); hypot does the same
thing and benchmark shows no change in speed.
