In addition, can you provide a bug record or a reproduction method? I think
it should also be fixed in the GCC community, and I will report the problems
you encounter in test to GCC Bugzilla.

If you build ffmpeg with this patch, "make fate" fails on the monkeysaudio
tests, on loongarch. That's about as much as I have so far.
It should indeed be fixed in GCC. You can of course just report this
above, but with that only that info, it is somewhat unlikely that anybody
will tend to the bug and fix it. To make it properly actionable, you need
to isolate the code which gets miscompiled, so GCC developers can compile
and observe that the resulting code is wrong (which may require some
loongarch knowledge to see what is wrong) without needing to build and run
the full ffmpeg fate.
