From 29a0fc9b2b6084e7a8810481df62a0fa496d8957 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 28 Sep 2012 18:31:59 +0900 Subject: perf tools: Convert to LIBELF_SUPPORT For building perf without libelf, we can set NO_LIBELF=1 as a argument of make. It then defines NO_LIBELF_SUPPORT macro for C code to do the proper handling. However it usually used in a negative semantics - e.g. #ifndef - so we saw double negations which can be misleading. Convert it to a positive form to make it more readable.
