Greg Clayton 1a30f4b78e Modify DWARFFormValue to remember the DWARFUnit that it was decoded with. ... Modifying DWARFFormValue to remember the DWARFUnit that it was encoded with can simplify the usage of instances of this class. Previously users would have to try and pass in the same DWARFUnit that was used to decode the form value and there was a possibility that a different DWARFUnit might be supplied to the functions that extract values (strings, CU relative references, addresses) and cause problems. This fixes this potential issue by storing the DWARFUnit inside the DWARFFormValue so that this mistake can't be made. Instances of DWARFFormValue are not stored permanently and are used as temporary values, so the increase in size of an instance of DWARFFormValue isn't a big deal. This makes decoding form values more bullet proof and is a change that will be used by future modifications. https://reviews.llvm.org/D26052 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@285594 91177308-0d34-0410-b5e6-96231b3b80d8		2016-10-31 16:46:02 +00:00
