From 25cd480e447eba47b8bdad1c9f95cadc074abc75 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 13 Jan 2015 10:19:12 -0300 Subject: tools: Remove bitops/hweight usage of bits in tools/perf We need to use lib/hweight.c for that, just like we do for lib/rbtree.c, so tools need to link hweight.o. For now do it directly, but we need to have a tools/lib/lk.a or .so that collects these goodies...
