From 650ab98d1d9551f0ca2180c0d88427acfcb081cf Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Llu=C3=ADs=20Vilanova?= Date: Tue, 3 Apr 2012 20:47:39 +0200 Subject: tracetool: Rewrite infrastructure as python modules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The tracetool script is written in shell and has hit several portability problems due to shell quirks or external tools across host platforms. Additionally the amount of string processing and lack of real data structures makes it tough to implement code generator backends for tracers that are more complex. This patch replaces the shell version of tracetool with a Python version. The new tracetool design is: scripts/tracetool.py - top-level script scripts/tracetool/backend/ - tracer backends live here (simple, ust) scripts/tracetool/format/ - output formats live here (.c, .h) There is common code for trace-events definition parsing so that backends can focus on generating code rather than parsing input. Support for all existing backends (nop, stderr, simple, ust, and dtrace) is added back in follow-up patches.
