https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83084 --- Comment #4 from Jakub Jelinek --- Ah, that might be it. I'd say UNSPEC_VOLATILE should never appear in DEBUG_INSNs. I'll have a look where it is introduced and why.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83084 --- Comment #3 from Segher Boessenkool --- Is this because the var_location contains an unspec_volatile? Is that a target bug, then?
