Fork of llvm with experimental commits and workarounds for RPCS3
740338b7fa
Summary: This method was not correct for entries in DWO files as it assumed it could just add up the CU and DIE offsets to get the absolute DIE offset. This is not correct for the DWO files, as here the CU offset will reference the skeleton unit, whereas the DIE offset will be the offset in the full unit in the DWO file. Unfortunately, this means that we are not able to determine the absolute DIE offset using the information in the .debug_names section alone, which means we have to offload some of this work to the users of this class. To demonstrate how this can be done, I've added/fixed the ability to lookup entries using accelerator tables in DWO files in llvm-dwarfdump. To make this happen, I've needed to make two extra changes in other classes: - made the DWARFContext method to lookup a CU based on the section offset public. I've needed this functionality to lookup a CU, and this seems like a useful thing in general. - made DWARFUnit::getDWOId call extractDIEsIfNeeded. Before this, the DWOId was filled in only if the root DIE happened to be parsed before we called the accessor. Since the lazy parsing is supposed to happen under the hood, calling extractDIEsIfNeeded seems appropriate.
