> r137602 added a call to the (deprecated; see llvm/include/llvm/ADT/APInt.h) APInt constructor that takes a size and pointer for a word array. The reason this constructor is deprecated is that it is prone to ambiguity with another constructor that takes a single word and a bool that denotes the signedness of the value. The deprecated constructor has been supplanted by one that takes a single ArrayRef parameter that encapsulates the size and a pointer to the word array. The attached patch calls the other constructor instead, and avoids the following build-breaker on gcc 4.5.2:
> DataExtractor.cpp: In function ‘uint32_t DumpAPInt(lldb_private::Stream*, const lldb_private::DataExtractor&, uint32_t, uint32_t, bool, unsigned int)’:
> DataExtractor.cpp:1362:55: error: call of overloaded ‘APInt(uint32_t, llvm::SmallVectorTemplateCommon<long unsigned int>::size_type, uint64_t*)’ is ambiguous
