# S_FILESTATIC records are unique in that they refer to the string table, but
# they do *not* go through the file checksums table.  They refer directly to
# the string table.  This makes for special handling in the linker, so it
# deserves a custom test.

# Clang doesn't currently generate these records, but MSVC does, so we have to
# be able to correctly link them.  These records are only generated when
# optimizations are turned on.
