From 0536d0cde931e89d33b10228950d455dd54d8a5f Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Thu, 2 Aug 2007 22:50:02 -0700 Subject: [PATCH] python: Improve support for python calling back to C++ member functions. Add support for declaring SimObjects to swig so their members can be wrapped. Make sim_object.i only contain declarations for SimObject. Create system.i to contain declarations for System. Update python code to properly call the C++ given the new changes. --HG-- extra : convert_revision : 82076ee69e8122d56e91b92d6767e356baae420a --- src/python/SConscript | 1 - src/python/generate.py | 24 ++++++++++++----- src/python/m5/SimObject.py | 42 +++++++++++++---------------- src/python/m5/internal/__init__.py | 1 - src/python/m5/params.py | 6 ++--- src/python/m5/simulate.py | 16 +++++------ src/python/swig/core.i | 6 +++++ src/python/swig/pyobject.hh | 20 -------------- src/python/swig/sim_object.i | 22 --------------- src/python/swig/system.i | 43 ++++++++++++++++++++++++++++++ src/sim/System.py | 2 ++ 11 files changed, 98 insertions(+), 85 deletions(-) create mode 100644 src/python/swig/system.i diff --git a/src/python/SConscript b/src/python/SConscript index f1b6a393f..b39c9ea9c 100644 --- a/src/python/SConscript +++ b/src/python/SConscript @@ -53,7 +53,6 @@ SwigSource('m5.internal', 'swig/core.i') SwigSource('m5.internal', 'swig/debug.i') SwigSource('m5.internal', 'swig/event.i') SwigSource('m5.internal', 'swig/random.i') -SwigSource('m5.internal', 'swig/sim_object.i') SwigSource('m5.internal', 'swig/stats.i') SwigSource('m5.internal', 'swig/trace.i') PySource('m5.internal', 'm5/internal/__init__.py') diff --git a/src/python/generate.py b/src/python/generate.py index 6a09b8106..99d0fb68c 100644 --- a/src/python/generate.py +++ b/src/python/generate.py @@ -274,17 +274,29 @@ class Generate(object): print >>out for obj in ordered_objs: - code = 'class %s ' % obj.cxx_class - if str(obj) != 'SimObject': - code += ': public %s ' % obj.__bases__[0] - code += '{};' + if obj.swig_objdecls: + for decl in obj.swig_objdecls: + print >>out, decl + continue + + code = '' + base = obj.get_base() + + code += '// stop swig from creating/wrapping default ctor/dtor\n' + code += '%%nodefault %s;\n' % obj.cxx_class + code += 'class %s ' % obj.cxx_class + if base: + code += ': public %s' % base + code += ' {};\n' klass = obj.cxx_class; if hasattr(obj, 'cxx_namespace'): - code = 'namespace %s { %s }' % (obj.cxx_namespace, code) + new_code = 'namespace %s {\n' % obj.cxx_namespace + new_code += code + new_code += '}\n' + code = new_code klass = '%s::%s' % (obj.cxx_namespace, klass) - print >>out, '%%ignore %s;' % klass print >>out, code for obj in ordered_objs: diff --git a/src/python/m5/SimObject.py b/src/python/m5/SimObject.py index 1e7d289e2..22c488f5d 100644 --- a/src/python/m5/SimObject.py +++ b/src/python/m5/SimObject.py @@ -128,6 +128,7 @@ class MetaSimObject(type): 'cxx_class' : types.StringType, 'cxx_type' : types.StringType, 'cxx_predecls' : types.ListType, + 'swig_objdecls' : types.ListType, 'swig_predecls' : types.ListType, 'type' : types.StringType } # Attributes that can be set any time @@ -225,6 +226,9 @@ class MetaSimObject(type): cls._value_dict['swig_predecls'] = \ cls._value_dict['cxx_predecls'] + if 'swig_objdecls' not in cls._value_dict: + cls._value_dict['swig_objdecls'] = [] + # Now process the _value_dict items.
