--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Guess that would be certainly possible, but best would be to propose such an
extension for inclusion into DWARF 6 because we are really tight in the
DW_OP_GNU_* opcode space.
BTW, if it would be IPA-VRP we could perhaps replace in debug stmts calls to
the singleton value range (if any), but in this case it is removed purely
because it is a const call and a signed char will never be equal to 128 (at
least on most -fsigned-char targets).
