--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Well, it is not about what arches you care about, but what arches we suppor=
t in
libsanitizer/configure.tgt (from *-linux*).
So, riscv64, aarch64, mips, arm, s390*, sparc*, powerpc*, x86.
So it is desirable to get it right for all these.
Thus, I think you want to use GLIBC_2.3.4 for Linux except on arm, riscv*,
x86_64 -mx32, powerpc64le and aarch64.
So you need to look up SANITIZE* macros for all of these...=
