This is not a record type that clang currently generates, but it is a record that is encountered in object files generated by cl. This record is unusual in that it refers directly to the string table instead of indirectly to the string table via the FileChecksums table. Because of this, it was previously overlooked and we weren't remapping the string indices at all. This would lead to crashes in MSVC when trying to display a variable whose debug info involved an S_FILESTATIC. Original bug report by Alexander Ganea Differential Revision: https://reviews.llvm.org/D41718 llvm-svn: 321883
