Description Tom Tromey 2023-03-01 22:01:03 UTC 
struct dynamic_prop is currently limited to a LONGEST, but
some compilers (GNAT in particular) will emit 128-bit types
for ranges in some cases.
This could be supported once more of the core is ready
for 128-bit integers.  For example the data could be
stored as a pointer-to-ULEB or pointer-to-16-bytes,
then manipulated using some wide-integer class.
Comment 1 Tom Tromey 2023-03-03 20:22:20 UTC 
This probably should also handle the bias of a range type.

This came up here:
https://github.com/rust-lang/rust/pull/102717
... in the context of rust C-like enums with 128 bit values.
