From fcd84f2fca49166dab2dba259eca6e633585763f Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Sun, 4 May 2008 00:25:02 +0200 Subject: [MIPS] Fix __fls for non-MIPS32/MIPS64 cpus Only MIPS32 and MIPS64 CPUs implement clz/dclz. Therefore don't export __ilog2() for non MIPS32/MIPS64 cpus and use generic __fls bitop code for these cpus.
