From 56a6b1eb7bfb5ace0b5cb9c149f502fbd101b8ab Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Sat, 15 Mar 2008 18:31:49 +0100 Subject: generic: implement __fls on all 64-bit archs Implement __fls on all 64-bit archs: alpha has an implementation of fls64. Added __fls(x) = fls64(x) - 1. ia64 has fls, but not __fls. Added __fls based on code of fls. mips and powerpc have __ilog2, which is the same as __fls. Added __fls = __ilog2. parisc, s390, sh and sparc64: Include generic __fls. x86_64 already has __fls.
