This reverts commit 99796d06dbe11c8f81376ad1d42e7f17d2eff6ae. Hint: Looking here because your manual invocation of something in 'check-asan' broke? You need a new symbolizer (after D123538). An upcoming patch will remove the internal metadata for global variables. With D123534 and D123538, clang now emits DWARF debug info for constant strings (the only global variable type it was missing), and llvm-symbolizer is now able to symbolize all global variable addresses (where previously it wouldn't give you the file:line information). Move ASan's runtime over from the internal metadata to DWARF. Differential Revision: https://reviews.llvm.org/D127552
