From 14086ed75d165b827b20de0101324bd8467d93c4 Mon Sep 17 00:00:00 2001 From: Enrico Granata Date: Wed, 10 Feb 2016 02:12:42 +0000 Subject: Change lldb.value.__int__() so that it takes into account the signedness of the value being cast to return a Python number with the proper value The explicit APIs on SBValue obviously remain if one wants to be explicit in intent, or override this guess, but since __int__() has to pick one, an educated guess is definitely better than than always going to signed regardless Fixes rdar://24556976 llvm-svn: 260349 --- lldb/scripts/Python/python-extensions.swig | 51 ++++++++++++++++++++++++++++-- 1 file changed, 48 insertions(+), 3 deletions(-) (limited to 'lldb/scripts/Python/python-extensions.swig') diff --git a/lldb/scripts/Python/python-extensions.swig b/lldb/scripts/Python/python-extensions.swig index fae7f40..1e43e53 100644 --- a/lldb/scripts/Python/python-extensions.swig +++ b/lldb/scripts/Python/python-extensions.swig @@ -1024,11 +1024,13 @@ class value(object): return complex (int(self)) def __int__(self): + is_num,is_sign = is_numeric_type(self.sbvalue.GetType().GetCanonicalType().GetBasicType()) + if is_num and not is_sign: return self.sbvalue.GetValueAsUnsigned() return self.sbvalue.GetValueAsSigned() - + def __long__(self): - return self.sbvalue.GetValueAsSigned() - + return self.__int__() + def __float__(self): return float (self.sbvalue.GetValueAsSigned()) @@ -1084,4 +1086,47 @@ class SBSyntheticValueProvider(object): return False +%} + +%pythoncode %{ + +# given an lldb.SBBasicType it returns a tuple +# (is_numeric, is_signed) +# the value of is_signed is undefined if is_numeric == false +def is_numeric_type(basic_type): + if basic_type == eBasicTypeInvalid: return (False,False) + if basic_type == eBasicTypeVoid: return (False,False) + if basic_type == eBasicTypeChar: return (True,False) + if basic_type == eBasicTypeSignedChar: return (True,True) + if basic_type == eBasicTypeUnsignedChar: return (True,False) + if basic_type == eBasicTypeWChar: return (True,False) + if basic_type == eBasicTypeSignedWChar: return (True,True) + if basic_type == eBasicTypeUnsignedWChar: return (True,False) + if basic_type == eBasicTypeChar16: return (True,False) + if basic_type == eBasicTypeChar32: return (True,False) + if basic_type == eBasicTypeShort: return (True,True) + if basic_type == eBasicTypeUnsignedShort: return (True,False) + if basic_type == eBasicTypeInt: return (True,True) + if basic_type == eBasicTypeUnsignedInt: return (True,False) + if basic_type == eBasicTypeLong: return (True,True) + if basic_type == eBasicTypeUnsignedLong: return (True,False) + if basic_type == eBasicTypeLongLong: return (True,True) + if basic_type == eBasicTypeUnsignedLongLong: return (True,False) + if basic_type == eBasicTypeInt128: return (True,True) + if basic_type == eBasicTypeUnsignedInt128: return (True,False) + if basic_type == eBasicTypeBool: return (False,False) + if basic_type == eBasicTypeHalf: return (True,True) + if basic_type == eBasicTypeFloat: return (True,True) + if basic_type == eBasicTypeDouble: return (True,True) + if basic_type == eBasicTypeLongDouble: return (True,True) + if basic_type == eBasicTypeFloatComplex: return (True,True) + if basic_type == eBasicTypeDoubleComplex: return (True,True) + if basic_type == eBasicTypeLongDoubleComplex: return (True,True) + if basic_type == eBasicTypeObjCID: return (False,False) + if basic_type == eBasicTypeObjCClass: return (False,False) + if basic_type == eBasicTypeObjCSel: return (False,False) + if basic_type == eBasicTypeNullPtr: return (False,False) + #if basic_type == eBasicTypeOther: + return (False,False) + %} \ No newline at end of file -- cgit v1.1
