commit 5609d77e683944439fae38323ecabc44a1eb4671 (HEAD -> clean)

    RISC-V: Test cbo.zero expansion for rv32

    We had an issue when expanding via cmo-zero for RV32.
    This was fixed upstream, but we don't have a RV32 test.
    Therefore, this patch introduces such a test.

    gcc/testsuite/ChangeLog:

            * gcc.target/riscv/cmo-zicboz-zic64-1.c: Fix for rv32.
