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.

This patch should not only land into GCC-14 but also should backport to GCC-13. PR target/110264 gcc/ChangeLog: * config/riscv/riscv-vsetvl.cc (insert_vsetvl): Fix bug.
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.
