From 19791f4a1385ffee97d3c13675fe245d015903fa Mon Sep 17 00:00:00 2001 From: tromey Date: Thu, 1 Oct 2009 20:43:13 +0000 Subject: [PATCH] 2009-10-01 Phil Muldoon * python/libstdcxx/v6/printers.py (StdListPrinter): Add -D_GLIBCXX_DEBUG implementation changes. Receive typename from printer registration. (StdListIteratorPrinter): Likewise. (StdDebugIteratorPrinter): New printer. (build_libstdcxx_dictionary): Add -D_GLIBCXX_DEBUG registration entries. Always pass a typename where the type can change. (StdSlistPrinter) Receive typename from printer registration. Use in printer output. (StdBitsetPrinter): Likewise. (StdDequePrinter): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@152385 138bc75d-0d04-0410-961f-82ee72b054a4 --- libstdc++-v3/python/libstdcxx/v6/printers.py | 99 ++++++++++++++++++++++------ 1 file changed, 80 insertions(+), 19 deletions(-) diff --git a/libstdc++-v3/python/libstdcxx/v6/printers.py b/libstdc++-v3/python/libstdcxx/v6/printers.py index a3d2ef1..a5e5b0d 100644 --- a/libstdc++-v3/python/libstdcxx/v6/printers.py +++ b/libstdc++-v3/python/libstdcxx/v6/printers.py @@ -64,28 +64,44 @@ class StdListPrinter: self.count = self.count + 1 return ('[%d]' % count, elt['_M_data']) - def __init__(self, val): + def __init__(self, typename, val): + self.typename = typename self.val = val def children(self): itype = self.val.type.template_argument(0) - nodetype = gdb.lookup_type('std::_List_node<%s>' % itype).pointer() + # If the inferior program is compiled with -D_GLIBCXX_DEBUG + # some of the internal implementation details change. + if self.typename == "std::list": + nodetype = gdb.lookup_type('std::_List_node<%s>' % itype).pointer() + elif self.typename == "std::__debug::list": + nodetype = gdb.lookup_type('std::__norm::_List_node<%s>' % itype).pointer() + else: + raise "Cannot cast list node for list printer." return self._iterator(nodetype, self.val['_M_impl']['_M_node']) def to_string(self): if self.val['_M_impl']['_M_node'].address == self.val['_M_impl']['_M_node']['_M_next']: - return 'empty std::list' - return 'std::list' + return 'empty %s' % (self.typename) + return '%s' % (self.typename) class StdListIteratorPrinter: "Print std::list::iterator" - def __init__(self, val): + def __init__(self, typename, val): self.val = val + self.typename = typename def to_string(self): itype = self.val.type.template_argument(0) - nodetype = gdb.lookup_type('std::_List_node<%s>' % itype).pointer() + # If the inferior program is compiled with -D_GLIBCXX_DEBUG + # some of the internal implementation details change. + if self.typename == "std::_List_iterator" or self.typename == "std::_List_const_iterator": + nodetype = gdb.lookup_type('std::_List_node<%s>' % itype).pointer() + elif self.typename == "std::__norm::_List_iterator" or self.typename == "std::__norm::_List_const_iterator": + nodetype = gdb.lookup_type('std::__norm::_List_node<%s>' % itype).pointer() + else: + raise "Cannot cast list node for list iterator printer." return self.val['_M_node'].cast(nodetype).dereference()['_M_data'] class StdSlistPrinter: @@ -154,7 +170,8 @@ class StdVectorPrinter: self.item = self.item + 1 return ('[%d]' % count, elt) - def __init__(self, val): + def __init__(self, typename, val): + self.typename = typename self.val = val def children(self): @@ -165,8 +182,8 @@ class StdVectorPrinter: start = self.val['_M_impl']['_M_start'] finish = self.val['_M_impl']['_M_finish'] end = self.val['_M_impl']['_M_end_of_storage'] - return ('std::vector of length %d, capacity %d' - % (int (finish - start), int (end - start))) + return ('%s of length %d, capacity %d' + % (self.typename, int (finish - start), int (end - start))) def display_hint(self): return 'array' @@ -248,6 +265,17 @@ class StdRbtreeIteratorPrinter: nodetype = nodetype.pointer() return self.val.cast(nodetype).dereference()['_M_value_field'] +class StdDebugIteratorPrinter: + "Print a debug enabled version of an iterator" + + def __init__ (self, val): + self.val = val + + # Just strip away the encapsulating __gnu_debug::_Safe_iterator + # and return the wrapped iterator value. + def to_string (self): + itype = self.val.type.template_argument(0) + return self.val['_M_current'].cast(itype) class StdMapPrinter: "Print a std::map or std::multimap" @@ -330,13 +358,14 @@ class StdSetPrinter: class StdBitsetPrinter: "Print a std::bitset" - def __init__(self, val): + def __init__(self, typename, val): + self.typename = typename self.val = val def to_string (self): # If template_argument handled values, we could print the # size.
