From 4b36673284f86c649b9d9ec5818b1912fde556b3 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Wed, 5 Dec 2007 19:08:24 +0300 Subject: [MIPS] Alchemy: replace ffs() with __ffs() Fix havoc wrought by commit 56f621c7f6f735311eed3f36858b402013023c18 -- au_ffs() and ffs() are equivalent, that patch should have just replaced one with another. Now replace ffs() with __ffs() which returns an unbiased bit number.
