Safe Pointers at the Intermediate Language or Hardware Level

Show all headers | View raw

Hi,

    Its been a long time since Java & .Net introduced safe address
    types to the computing world.

    My question is have we settled on what could be a proper representation
    for safe pointers ?

    Some Mainframes like the 390 have historically supported safe pointers,
    I remember.

Sincerely,
Seima Rao.
[I looked at my S/390 Principles of Operation, and I see a bunch of stuff
for tracing, but nothing that looks like safe pointers.  I'd think it was
hardware dependent, e.g., if a machine has a fairly clean and efficient
trap for an unmapped zero address, you'd use that, but if it doesn't, you'd
do something else. -John]
