From 70cb4e963f77dae90ae2aa3dd9385a43737c469f Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Tue, 30 Oct 2012 11:56:02 +0800 Subject: perf tools: Add a global variable "const char *input_name" Currently many perf commands annotate/evlist/report/script/lock etc all support "-i" option to chose a specific perf data, and all of them create a local "input_name" to save the file name for that perf data. Since most of these commands need it, we can add a global variable for it, also it can some other benefits: 1. When calling script browser inside hists/annotation browser, it needs to know the perf data file name to run that script. 2. For further feature like runtime switching to another perf data file, this variable can also help.
