From 5079a0d32f2824445cf593dfbcb65598eaa97dee Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich" Date: Tue, 27 Nov 2012 11:32:38 -0800 Subject: Remove assembly coded log2 function As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.
