I completely know the cause: On the Binutils side, new multiply-only instruction subset extension 'Zmmul' is being added. I sent a patchset which spans *both Binutils and GDB* but *only Binutils part is committed.* This is the one (same but both to binutils and gdb-patches ML): <https://sourceware.org/pipermail/binutils/2022-August/122653.html> <https://sourceware.org/pipermail/gdb-patches/2022-August/191295.html> I'm proposing remaining part (GDB / simulator part) as a separate patchset but there's no response from the GDB side... <https://sourceware.org/pipermail/gdb-patches/2022-August/191609.html> <https://sourceware.org/pipermail/gdb-patches/2022-September/191841.html> (ping 1) <https://sourceware.org/pipermail/gdb-patches/2022-September/191995.html> (ping 2) Not being able to run the multiply instructions on the simulator is clearly a release blocker for GDB 13.1. So I'm reporting this to track this issue. My copyright assignment to both Binutils and GDB is complete and I'm now even a "write after approval" committer. If a maintainer gives me an approval, I can commit it in a day.
