If it is DWARF4 only, then it could be considered an extension, but if it
applies to DWARF3 too, then it is certainly invalid.
I don't speak Ada, do you have some minimal testcase?
I've tried to write it in Fortran, but it seems to ignore it alltogether
(probably a bug):
integer(kind=16), parameter :: a = 18014398509481984_16
integer(kind=16), parameter :: b = a * a
integer(kind=4) :: c (b : b + 32)
c(b + 2) = 1
end
