2007-07-28Turn the instruction tracing code into pluggable sim objects.Gabe Black
These need to be refined a little still and given parameters. --HG-- extra : convert_revision : 9a8f5a7bd9dacbebbbd2c235cd890c49a81040d7
2007-07-23Major changes to how SimObjects are created and initialized. Almost allNathan Binkert
creation and initialization now happens in python. Parameter objects are generated and initialized by python. The .ini file is now solely for debugging purposes and is not used in construction of the objects in any way. --HG-- extra : convert_revision : 7e722873e417cb3d696f2e34c35ff488b7bff4ed
2007-06-19Make branches work by repopulating the predecoder every time through. This ↵Gabe Black
is probably fine as far as the predecoder goes, but the simple cpu might want to not refetch something it already has. That reintroduces the self modifying code problem though. --HG-- extra : convert_revision : 802197e65f8dc1ad657c6b346091e03cb563b0c0
