--- Comment #5 from Alex Coplan <acoplan at gcc dot gnu.org> ---
FWIW, the ICE was "fixed" with
r11-4912-g46c705e70e078f6a1920d92e49042125d5e18495:

commit 46c705e70e078f6a1920d92e49042125d5e18495

    aarch64: Support SVE comparisons for unpacked integers

    This patch adds support for comparing unpacked SVE integer vectors,
    such as byte elements stored in the bottom bytes of halfword
    containers.  It also adds support for selects between unpacked
    SVE vectors (both integer and floating-point), since selects and
    compares are closely tied via the vcond optab interface.

so not sure if the issue was really fixed or perhaps just hidden.=
