clang/StaticAnalyzer: Stop using SourceManager::getBuffer

Authored by dexonsmith on Oct 14 2020, 11:11 AM.



Update clang/lib/StaticAnalyzer to stop relying on a MemoryBuffer*, using the MemoryBufferRef from getBufferOrNone or the Optional<MemoryBufferRef> from getBufferOrFake, depending on whether there's logic for checking validity of the buffer. The change to clang/lib/StaticAnalyzer/Core/IssueHash.cpp is potentially a functionality change, since the logic was wrong (it checked for nullptr, which was never returned by the old API), but if that was reachable the new behaviour should be better.
