From ab6540d55e8d57609c1e0c18b40269b05e231ce7 Mon Sep 17 00:00:00 2001 From: Prerna Saxena Date: Mon, 9 Aug 2010 11:48:32 +0100 Subject: trace: Add trace file name command-line option This patch adds an optional command line switch '-trace' to specify the filename to write traces to, when qemu starts. Eg, If compiled with the 'simple' trace backend, [temp@system]$ qemu -trace FILENAME IMAGE Allows the binary traces to be written to FILENAME instead of the option set at config-time.
