--- Comment #1 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- ISTM that -fharden-control-flow-redundancy is only instrumental to trigger the latent problem, but the real problem is in the back end: aarch64_restore_za emits a aarch64_cbnedi1 unconditionally, but insn aarch64_cb<optab><mode>1 is disabled on aarch64_track_speculation, which the test uses.
