GEM5_DEPRECATED(message) expands to the [[gnu::deprecated(message)]]
attribute on gnu compatible compilers and marks an entity (function,
variable, etc) as deprecated. The msg parameter should be used to tell
the user what they should do to move away from the deprecated entity.
GEM5_DEPRECATED_MACRO(name, definition, message) is used inside an
expression-like macro with definition "definition" to mark that macro as
deprecated with message "message". For instance, if there were macros
like this:
#define SUM(a, b) ((a) + (b))
#define ONE 1
We could mark that as deprecated like so:
#define SUM(a, b) GEM5_DEPRECATED_MACRO(SUM, (a) + (b), \
"The SUM macro is deprecated, use the + operator instead.")
#define ONE GEM5_DEPRECATED_MACRO(ONE, 1, "Use the literal 1.")
Note that this macro should not be used for macros which, for instance,
declare variables, since it assumes the body of the macro expands into
an expression and not a statement or statements.

This is the gem5 simulator. The main website can be found at http://www.gem5.org A good starting point is http://www.gem5.org/about, and for more information about building the simulator and getting started please see http://www.gem5.org/documentation and http://www.gem5.org/documentation/learning_gem5/introduction. To build gem5, you will need the following software: g++ or clang, Python (gem5 links in the Python interpreter), SCons, SWIG, zlib, m4, and lastly protobuf if you want trace capture and playback support. Please see http://www.gem5.org/documentation/general_docs/building for more details concerning the minimum versions of the aforementioned tools. Once you have all dependencies resolved, type 'scons build/<ARCH>/gem5.opt' where ARCH is one of ARM, NULL, MIPS, POWER, SPARC, or X86. This will build an optimized version of the gem5 binary (gem5.opt) for the the specified architecture. See http://www.gem5.org/documentation/general_docs/building for more details and options. The basic source release includes these subdirectories: - configs: example simulation configuration scripts - ext: less-common external packages needed to build gem5 - src: source code of the gem5 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. If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
