I cannot compile highway on riscv/rv64gcv1p0 with gcc-13.

Compilation fails with:

This is not a duplicate of PR/109535 since I can compile the previously
mentionned TU transform_test.cc just fine.

Thanks for reporting this. I am trying to reduce the testcase. Hopefully will
fix it today. But we need kito or Jeff to backport it into GCC-13.

Thanks.

I fixed this issue:
https://gcc.gnu.org/pipermail/gcc-patches/2023-June/621953.html

Hope it will be landed into trunk and backport to GCC-13 soon.

Thanks.

    RISC-V: Fix VL operand bug in VSETVL PASS[PR110264]

    This patch fixes this issue happens on both GCC-13 and GCC-14.
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110264

    The testcase is too big and I failed to reduce it so I didn't append
    test into this patch.

    This patch should not only land into GCC-14 but also should backport to
GCC-13.

--- Comment #5 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Note that Pan can cherry pick it into gcc-13.  Typically folks wait a week or
so after the patch is on the trunk to see if there's any fallout.  Given that I
don't expect gcc-13.2 until late summer, we've certainly got time.
