From 4e34d9588b46f44a4dba718606913133f15e4b21 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 2 Oct 2012 01:32:51 +0900 Subject: perf tools: Convert to BACKTRACE_SUPPORT For building perf without stack backtrace debug, we can set NO_BACKTRACE=1 as a argument of make. It then defines NO_BACKTRACE 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 and add _SUPPORT suffix for consistency.
