From e0d66c74b09f5103eef441a98b68056c4dae4cac Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 31 Jul 2014 14:47:37 +0900 Subject: [PATCH] perf tools: Save column length in perf_hpp_fmt Save column length in the hpp format and pass it to print functions. This is a preparation for users to control column width in the output.
