From ce2d17ca7f85dcade62cd608601a0d52ccdaf0e6 Mon Sep 17 00:00:00 2001 From: Akihiro Nagai Date: Wed, 23 Mar 2011 16:29:39 +0900 Subject: perf top: Fix uninitialized 'counter' variable builtin-top.c has an uninitialized variable. gcc(version 4.5.1) warns about it and it results in build failure: builtin-top.c: In function 'display_thread': builtin-top.c:518:9: error: 'counter' may be used uninitialized This situation can indeed trigger, if the getline() call in prompt_integer() fails.

Good also because it does an extra validation, checking that the ID is valid when present. When that is not the case, the overhead is just a branch + function call (perf_evlist__id2evsel).
