From 7752f1b096e13991f20b59fd11ba73da3809d93c Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Mon, 10 May 2010 13:12:07 -0400 Subject: perf probe: Don't compile CFI related code if elfutils is old Check elfutils version, and if it is old don't compile CFI analysis code. This allows to compile perf with old elfutils.
