--- Comment #8 from seurer at gcc dot gnu.org --- This is the way it came from upstream (llvm) and the solution for powerpc64 was copied from what aarch64 did before. What is really needed is a workable solution from whoever does sanitizer development that works despite the huge ranges of addresses that ASLR now uses.
