(Still not perfect though.)
arch/alpha/isa_desc:
Do a better job of factoring out CPU model. (Still not perfect though.)
Pull execute() methods out of class declarations into separate section
of file, allowing (1) easier replication for different CPU models and
(2) a path to putting them all in a separate file. Force all instruction
execution context into a single model-dependent class (SimpleCPU itself
for SimpleCPU, DynInst for FullCPU).
arch/isa_parser.py:
Do a better job of factoring out CPU model. (Still not perfect though.)
Pull execute() methods out of class declarations into separate section
of file, allowing (1) easier replication for different CPU models and
(2) a path to putting them all in a separate file.
Also restructure top level to allow parser to run under interactive
interpreter session for easier debugging.
cpu/exec_context.hh:
Add a few new methods to clean up isa_desc.
cpu/simple_cpu/simple_cpu.cc:
cpu/static_inst.hh:
StaticInst::execute no longer takes a CPU and an ExecContext,
just a unified FooCPUExecContext.
cpu/simple_cpu/simple_cpu.hh:
Add methods to redirect calls to ExecContext so SimpleCPU
can act as sole instruction execution context for itself.
Typedef SimpleCPU to SimpleCPUExecContext.

This is release m5_1.0_beta1 of the M5 simulator. This file contains brief "getting started" information and release notes. For more information, see http://m5.eecs.umich.edu. If you have questions, please send mail to m5sim-users@lists.sourceforge.net. WHAT'S INCLUDED (AND NOT) ------------------------- Since you're reading this file, presumably you've managed to untar the distribution. The archive you've unpacked has three subdirectories: - m5: the simulator itself - m5-test: regression tests and scripts to run them - ext: less-common external packages needed to build m5 (currently just "ply") Although M5 is capable of full-system simulation, the only OS it currently supports is the proprietary Compaq/HP Tru64 version of Unix. We are thus unable to distribute bootable disk images freely. If you have a Tru64 license and are interested in obtaining disk images, contact us at m5-dev@eecs.umich.edu. GETTING STARTED --------------- The following steps will build and test the simulator. The variable "$top" refers to the top directory where you've unpacked the files, i.e., the one containing the m5, m5-test, and ext directories. cd $top/m5/setup ./setup ALPHA # set up build/ALPHA directory cd $top/m5/build/ALPHA make m5.opt # use "-j N" if you've got an MP system # wait for build... cd $top/m5-test ./do-tests.pl -B ALPHA # test what you just built # wait for tests to run... # should end with "finished do-tests successfully!" If you run into errors regarding m5/arch/alpha/decoder.cc, just "touch" that file to update its timestamp. This file is generated from a compact ISA description using a program written in Python. If you have Python 2.2.2 or later installed on your system, you should be able to generate it yourself, but if you don't have Python (or have an older version), you may run in to trouble. Since we've shipped a working copy of decoder.cc, it's not necessary to have Python to build M5 (unless you start modifying the ISA decription). Unfortunately, sometimes make gets confused and tries to do so anyway. The "touch" should convince make to stop trying.
