2018-08-17ruby: remove unused code inside '#if 0 ... #endif'Brandon Potter
The commented code contains bitrot. It is not clear how to fix the code so remove it. The code will not compile if the preprocessor defines are removed. The llocker and uulocker variables that are used as indices into the persistent_randomize array are undefined. It's not clear what they should be from the current code. 5ab13e2deb shows when the lines were last modified. The functionality contained in the comments probably have not been used since that time. (This is an example of why one should never add commented code that is enabled by removing defines. The code rots and sits in the source forever.)

These overloads of sc_trace take the unsigned version of some primitive types. The compiler thought it was ambiguous how to convert an unsigned integer value into a signed one since there were several different functions which took signed integer parameters of various sizes. These versions of sc_trace aren't in the standard, but they are in the Accellera implementation and do fix building of the regression tests.

2018-08-15systemc: Remove references to internal constants from the tests.Gabe Black
The tests were referring to constants defined in the Accellera systemc implementation which identified various log message types. This change replaces those (sometimes quite long) string constants with their actual value. This doesn't make that interface any more fragile since the constant value won't track between the Accellera version and this one, but it does make its fragility more explicit by using the value directly. If in the future we decide to hide the magical nature of those particular string constants, we could make them into our own constants in the implementation. Regardless, the tests shouldn't refer to internal details of the implementation.

The spec defines these constants to be macros, but the regression test refers to them using the sc_core namespace.

This change converts the macros into enums like in the Accellera implementation to get the regression tests to build.

2018-08-15systemc: Include boost/bind.hpp in the systemc header.Gabe Black
The systemc spec says that sc_bind, sc_ref and sc_cref macros should expand to boost::bind, boost::ref, and boost::cref respectively, but that it's "use is not mandantory". Unfortunately, the regression tests use those macros without actually including the boost headers for themselves, and so they won't compile without dragging in these boost headers as a dependency. This should be mostly ok to include here since gem5 itself shouldn't include systemc, just the sub headers that systemc brings in. systemc code which includes systemc *will* have a dependency on boost, but that at least contains the new dependency somewhat.

2018-08-15systemc: Fill out some of the sc_vector.hh classes.Gabe Black
The iterator class needs to have some operators, etc., defined so that tests written against it can compile correctly. The implementations were heavily influenced by the Accellera implementation. Also it should be noted that the systemc spec is incorrect where it defines these classes. When implemented like they are in the Accellera version, the versions of bind in sc_vector_assembly which take sc_vector<T>::iterator and iterator parameters are different, and so they can overload each other. If implemented as described by the spec however, those types are the same and the code won't compile.

2018-08-15systemc: Add a script which automates building and running tests.Gabe Black
The only required option for the script is the path to a build directory, for instance build/ARM. It uses that when running scons and when referring to generated files (like the built versions of the tests). It uses the location of the script itself to find source files, like the "golden" version of outputs. This script runs tests in three phases, compilation, running, and then verification. By default, all three phases are run for all tests, but which phases run and how they work can be customized by specifying them explicitly on the command line with the --phase option. Each time the --phase option shows up on the command line, it should be followed by the name of the phase being specified. That both declares that that phase should be run, and also that any subsequent options apply to that phase, at least until the next --phase option. Currently, only the "compile" and "execute" phases are implemented, and only the "compile" phase has been tested at all or has any options defined. The "compile" phase simply takes all the options it was given and pass them on to scons. The "verify" phase simply prints a message which says what it would have verified. The script can list the available tests with the --list option, as determined by the json systemc test manifest file which scons can generate, and which the script can refresh if passed the --update-json option. You can also specify what "flavor" of build you want to do, ie opt, debug, fast, etc., with the --flavor option. Only one flavor can be tested at a time, but that should be the desired behavior most of the time. If multiple flavors need to be tested, the script can be invoked multiple times. Finally, there is a --filter option which accepts a python expression as a string. That expression is evaluated in the namespace of the properties of each test in the json file, and if it returns true then that test is run. For instance, to verify only compile_only tests, you would use: systemc/tests/verify.py build/ARM --filter 'compile_only' To test only compile_only tests named bob, you would run this: systemc/tests/verify.py build/ARM --filter \ 'compile_only && name ="bob"' Also included is a simple config.py which is the beginning of a config which will run the systemc regression tests. Right now, all it knows how to do is run sc_main.

2018-07-24systemc: Add systemc and systemc.h header files.Gabe Black
These are the header files as defined by the standard, although some predefined channel types and most of the sc_dt namespace have yet to be stubbed out, and so those portions are excluded.

2018-07-24systemc: Seperate the "external" header interface.Gabe Black
Most (but not all) of the SystemC headers are part of the "external" interface that an existing, standard compliant module would include through <systemc.h> or <systemc>. Since those follow slightly different rules (relative includes, no gem5 includes), this change separates them out so that they're easier to identify. Also, this change moves the other files into a "core" subdirectory, with the intention to add a "dt", aka data type, directory some time in the future when those standard defined types are implemented.
