When redirecting fetch to handle branches, the npc of the current pc state needs to be left alone. This change makes the pc state record whether or not the npc already reflects a real value by making it keep track of the current instruction size, or if no size has been set.
This is release 2.0_beta6 of the M5 simulator. For detailed information about building the simulator and getting started please refer to http://www.m5sim.org. Specific pages of interest are: http://www.m5sim.org/wiki/index.php/Compiling_M5 http://www.m5sim.org/wiki/index.php/Running_M5 Short version: 1. If you don't have SCons version 0.96.91 or newer, get it from http://wwww.scons.org. 2. If you don't have SWIG version 1.3.28 or newer, get it from http://wwww.swig.org. 3. In this directory, type 'scons build/ALPHA_SE/tests/debug/quick'. This will build the debug version of the m5 binary (m5.debug) for the Alpha syscall emulation target, and run the quick regression tests on it. If you have questions, please send mail to m5-users@m5sim.org WHAT'S INCLUDED (AND NOT) ------------------------- The basic source release includes these subdirectories: - m5: - src: source code of the m5 simulator - tests: regression tests - ext: less-common external packages needed to build m5 To run full-system simulations, you will need compiled console, PALcode, and kernel binaries and one or more disk images. These files are collected in a separate archive, m5_system.tar.bz2. This file can he downloaded separately. M5 supports Linux 2.4/2.6, FreeBSD, and the proprietary Compaq/HP Tru64 version of Unix. We are able to distribute Linux and FreeBSD bootdisks, but we are unable to distribute bootable disk images of Tru64 Unix. If you have a Tru64 license and are interested in obtaining disk images, contact us at m5-users@m5sim.org
