From 95485b1cda827e4db7102ad5fde1791087a0f4c5 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 28 Sep 2012 18:32:00 +0900 Subject: perf tools: Convert to LIBUNWIND_SUPPORT For building perf without libunwind, we can set NO_LIBUNWIND=1 as a argument of make. It then defines NO_LIBUNWIND_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. Also change NO_PERF_REGS macro to HAVE_PERF_REGS for the same reason.
