Before this changeset, all local variables of type Entry and TBE were considered to be pointers, but an immediate use of said variables would not be automatically deferenced in SLICC-generated code. Instead, deferences occurred when such variables were passed to functions, and were automatically dereferenced in the bodies of the functions (e.g. the implicitly passed cache_entry). This is a more general way to do it, which leaves in place the assumption that parameters to functions and local variables of type AbstractCacheEntry and TBE are always pointers, but instead of dereferencing to access member variables on a contextual basis, the dereferencing automatically occurs on a type basis at the moment a member is being accessed. So, now, things you can do that you couldn't before include: Entry foo := getCacheEntry(address); cache_entry.DataBlk := foo.DataBlk; or cache_entry.DataBlk := getCacheEntry(address).DataBlk; or even cache_entry.DataBlk := static_cast(Entry, pointer, cache.lookup(address)).DataBlk;
This is 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 0.98.1 or newer, get it from http://wwww.scons.org. 2. If you don't have SWIG version 1.3.31 or newer, get it from http://wwww.swig.org. 3. Make sure you also have gcc version 3.4.6 or newer, Python 2.4 or newer (the dev version with header files), zlib, and the m4 preprocessor. 4. 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: - configs: simulation configuration scripts - ext: less-common external packages needed to build m5 - src: source code of the m5 simulator - system: source for some optional system software for simulated systems - tests: regression tests - util: useful utility programs and files To run full-system simulations, you will need compiled system firmware (console and PALcode for Alpha), kernel binaries and one or more disk images. These files for Alpha are collected in a separate archive, m5_system.tar.bz2. This file can he downloaded separately. Depending on the ISA used, M5 may support 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
