From cf59002fdebc9c00ee29233e65bc39dd69e0eaf6 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 31 Jul 2014 14:47:39 +0900 Subject: [PATCH] perf top: Add -w option for setting column width Add -w/--column-widths option like perf report does so that users are able to see symbols even with some very long C++ library/functions. It can be a list separated by comma for each column. $ perf top -w 0,20,30 The value of 0 means there's no limit.
