2012-05-10stats: fix compilation of unit test.Ali Saidi
2012-04-14clang/gcc: Fix compilation issues with clang 3.0 and gcc 4.6Andreas Hansson
This patch addresses a number of minor issues that cause problems when compiling with clang >= 3.0 and gcc >= 4.6. Most importantly, it avoids using the deprecated ext/hash_map and instead uses unordered_map (and similarly so for the hash_set). To make use of the new STL containers, g++ and clang has to be invoked with "-std=c++0x", and this is now added for all gcc versions >= 4.6, and for clang >= 3.0. For gcc >= 4.3 and <= 4.5 and clang <= 3.0 we use the tr1 unordered_map to avoid the deprecation warning. The addition of c++0x in turn causes a few problems, as the compiler is more stringent and adds a number of new warnings. Below, the most important issues are enumerated: 1) the use of namespaces is more strict, e.g. for isnan, and all headers opening the entire namespace std are now fixed. 2) another other issue caused by the more stringent compiler is the narrowing of the embedded python, which used to be a char array, and is now unsigned char since there were values larger than 128. 3) a particularly odd issue that arose with the new c++0x behaviour is found in range.hh, where the operator< causes gcc to complain about the template type parsing (the "<" is interpreted as the beginning of a template argument), and the problem seems to be related to the begin/end members introduced for the range-type iteration, which is a new feature in c++11. As a minor update, this patch also fixes the build flags for the clang debug target that used to be shared with gcc and incorrectly use "-ggdb".
2012-04-13SCons: restore Werror option in src/SConscriptSteve Reinhardt
Partial backout of cset 8b223e308b08. Although it's great that there's currently no need for Werror=false in the current tree, some of us have uncommitted code that still needs this option.
2012-04-09tests: Fix building unit tests.Gabe Black
Unit tests shouldn't build in gem5's main function because they have thier own.
2012-03-22Scons: Remove Werror=False in SConscript filesAndreas Hansson
This patch removes the overriding of "-Werror" in a handful of cases. The code compiles with gcc 4.6.3 and clang 3.0 without any warnings, and thus without any errors. There are no functional changes introduced by this patch. In the future, rather than ypassing "-Werror", address the warnings.
2012-03-06build scripts: Made minor modifications to reduce build overhead time.Marc Orr
1. --implicit-cache behavior is default. 2. makeEnv in src/SConscript is conditionally called. 3. decider set to MD5-timestamp 4. NO_HTML build option changed to SLICC_HTML (defaults to False)
2012-01-31clang: Enable compiling gem5 using clang 2.9 and 3.0Koan-Sin Tan
This patch adds the necessary flags to the SConstruct and SConscript files for compiling using clang 2.9 and later (on Ubuntu et al and OSX XCode 4.2), and also cleans up a bunch of compiler warnings found by clang. Most of the warnings are related to hidden virtual functions, comparisons with unsigneds >= 0, and if-statements with empty bodies. A number of mismatches between struct and class are also fixed. clang 2.8 is not working as it has problems with class names that occur in multiple namespaces (e.g. Statistics in kernel_stats.hh). clang has a bug (http://llvm.org/bugs/show_bug.cgi?id=7247) which causes confusion between the container std::set and the function Packet::set, and this is currently addressed by not including the entire namespace std, but rather selecting e.g. "using std::vector" in the appropriate places.
2012-01-09SWIG: Make gem5 compile and link with swig 2.0.4Andreas Hansson
To make gem5 compile and run with swig 2.0.4 a few minor fixes are necessary, the fail label issues by swig must not be treated as an error by gcc (tested with gcc 4.2.1), and the vector wrappers must have SWIGPY_SLICE_ARG defined which happens in pycontainer.swg, included through std_container.i. By adding the aforementioned include to the vector wrappers everything seems to work.
2011-11-09GCC: Guard some gcc flags so they're used when available and needed.Gabe Black
2011-10-31GCC: Get everything working with gcc 4.6.1.Gabe Black
And by "everything" I mean all the quick regressions.
2011-10-20scons/swig: refactor some of the scons/SWIG codeSteve Reinhardt
- Move the random bits of SWIG code generation out of src/SConscript file and into methods on the objects being wrapped. - Cleaned up some variable naming and added some comments to make the process a little clearer. - Did a little generated file/module renaming: - vptype_Foo now Foo_vector - init_Foo is now Foo_init This makes it easier to see all the Foo-related files in a sorted directory listing. - Made cxx_predecls and swig_predecls normal SimObject classmethods. - Got rid of swig_objdecls hook, even though this breaks the System objects get/setMemoryMode method exports. Will be fixing this in a future changeset.
2011-10-17scons: fix building of shared objectsNathan Binkert
2011-06-02scons: rename TraceFlags to DebugFlagsNathan Binkert
2011-06-02scons: rename some things from m5 to gem5Nathan Binkert
The default generated binary is now gem5.<type> instead of m5.<type>. The latter does still work but gem5.<type> will be generated first and then m5.<type> will be hard linked to it.
2011-06-02copyright: Add code for finding all copyright blocks and create a COPYING fileNathan Binkert
The end of the COPYING file was generated with: % python ./util/find_copyrights.py configs src system tests util Update -C command line option to spit out COPYING file
2011-04-20scons: Allow the build directory live under an EXTRAS directoryBrad Danofsky
2011-04-15unittest: Make unit tests capable of using swig and python, convert stattestNathan Binkert
2011-04-15scons: make a flexible system for guarding source filesNathan Binkert
This is similar to guards on mercurial queues and they're used for selecting which files are compiled into some given object. We already do something similar, but it's mostly hard coded for the m5 binary and the m5 library and I'd like to make it more flexible to better support the unittests
2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help
2011-03-11SCons: Stop embedding the mercurial revision into the binary.Gabe Black
This causes a lot of rebuilds that could have otherwise possibly been avoided, and, more annoyingly, a lot of unnecessary rerunning of the regressions. The benefits of having the revision in the output haven't materialized, so this change removes it.
2011-02-14Info: Clean up some info files.Gabe Black
Get rid of RELEASE_NOTES since we no longer do releases, update some of the information in README, and update the date in LICENSE.
2011-01-07scons: show sources and targets when building, and colorize output.Steve Reinhardt
I like the brevity of Ali's recent change, but the ambiguity of sometimes showing the source and sometimes the target is a little confusing. This patch makes scons typically list all sources and all targets for each action, with the common path prefix factored out for brevity. It's a little more verbose now but also more informative. Somehow Ali talked me into adding colors too, which is a whole 'nother story.
2011-01-03Make commenting on close namespace brackets consistent.Steve Reinhardt
Ran all the source files through 'perl -pi' with this script: s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|; s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|; s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.
2010-12-21scons: remove extra dependenciesNathan Binkert
2010-11-15SCons: Cleanup SCons output during compileAli Saidi
2010-11-06scons: Replace the build_dir parameter to SConscript with variant_dir.Gabe Black
The build_dir parameter name has been deprecated and replaced with variant_dir. This change switches us over to avoid warning spew in newer versions of scons.
2010-09-12swig: make all generated files go into the m5.internal packageNathan Binkert
This is necessary because versions of swig older than 1.3.39 fail to do the right thing and try to do relative imports for everything (even with the package= option to %module). Instead of putting params in the m5.internal.params package, put params in the m5.internal package and make all param modules start with param_. Same thing for m5.internal.enums. Also, stop importing all generated params into m5.objects. They are not necessary and now with everything using relative imports we wound up with pollution of the namespace (where builtin-range got overridden). --HG-- rename : src/python/m5/internal/enums/__init__.py => src/python/m5/internal/enums.py rename : src/python/m5/internal/params/__init__.py => src/python/m5/internal/params.py
2010-09-09scons: Stop building the big monolithic swigged params moduleNathan Binkert
kill params.i and create a separate .i for each object (param, enums, etc.)
2010-09-09init: don't build files that centralize python and swig codeNathan Binkert
Instead of putting all object files into m5/object/__init__.py, interrogate the importer to find out what should be imported. Instead of creating a single file that lists all of the embedded python modules, use static object construction to put those objects onto a list. Do something similar for embedded swig (C++) code.
2010-09-09scons: use code_formatter wherever we can in the build systemNathan Binkert
2010-07-21python: Add mechanism to override code compiled into the exectuableNathan Binkert
If the user sets the environment variable M5_OVERRIDE_PY_SOURCE to True, then imports that would normally find python code compiled into the executable will instead first check in the absolute location where the code was found during the build of the executable. This only works for files in the src (or extras) directories, not automatically generated files. This is a developer feature!
2010-04-15scons: don't maintain files in sorted orderNathan Binkert
This causes builds to happen in sorted order rather than in declaration order. This gets annoying when you make a global change and then you notice that the files that are being compiled are jumping around the directory hierarchy.
2009-11-08scons: deal with generated .py files properlySteve Reinhardt
2009-09-26python: Fix m5.defines so grabbing flags works correctlyNathan Binkert
2009-09-23arch: nuke arch/isa_specific.hh and move stuff to generated config/the_isa.hhNathan Binkert
2009-09-22params: small cleanup to param description internalsNathan Binkert
2009-09-22python: Move more code into m5.util allow SCons to use that code.Nathan Binkert
Get rid of misc.py and just stick misc things in __init__.py Move utility functions out of SCons files and into m5.util Move utility type stuff from m5/__init__.py to m5/util/__init__.py Remove buildEnv from m5 and allow access only from m5.defines Rename AddToPath to addToPath while we're moving it to m5.util Rename read_command to readCommand while we're moving it Rename compare_versions to compareVersions while we're moving it. --HG-- rename : src/python/m5/convert.py => src/python/m5/util/convert.py rename : src/python/m5/smartdict.py => src/python/m5/util/smartdict.py
2009-06-12scons: Make shared library builds work againNathan Binkert
Compile gzstream as position independent code use the PIC version of date for shared libs...oops
2009-06-05scons: Make it so that the processing of trace flags does not depend on orderNathan Binkert
2009-05-04scons: re-work the *Source functions to take more information.Nathan Binkert
Start by turning all of the *Source functions into classes so we can do more calculations and more easily collect the data we need. Add parameters to the new classes for indicating what sorts of flags the objects should be compiled with so we can allow certain files to be compiled without Werror for example.
2009-04-21SCons: Export export_vars so SConsopts files can add to themNathan Binkert
2009-02-09scons: Require SCons version 0.98.1Nathan Binkert
This allows me to clean things up so we are up to date with respect to deprecated features. There are many features scheduled for permanent failure in scons 2.0 and 0.98.1 provides the most compatability for that. It also paves the way for some nice new features that I will add soon
2009-02-09scons: Don't build the intermediate static library unless explicitly requested.Nathan Binkert
This means that similar to libm5_fast.so, you need to explicitly build build/ALPHA_SE/libm5_fast.a if you want it.
2009-01-30SCons: Fix how we get Mercurial revision information since internals keep ↵Ali Saidi
changing.
2009-01-19tracing: panic() if people try to use tracing, but TRACING_ON is not set.Nathan Binkert
Also clean things up so that help strings can more easily be added. Move the help function into trace.py

Scons bug id: 2006 M5 Bug id: 308
2008-11-10SCons: Allow top level directory of EXTRAS able to contain SConscripts.Nathan Binkert
The current EXTRAS will fail if the top level directory pointed to by EXTRAS has a SConscript file in it. We allow this by including the directory name of the EXTRA in the build directory which prevents a clash between src/SConscript and extra/SConscript. Maintain compatibility with older uses of EXTRAS by adding a -I for each top level extra directory.
2008-10-10swig: Add in a %rename to allow the same name to appear in multiple namespaces.Nathan Binkert
