- Subject: Non-uniform address spaces
Any suggestions on how to support a target which has
a non-uniform address space? An address is a tuple which
includes a processor id, a thread id, and an offset.
There is a mapping function which translates the tuple
into a physical address.
Ideally, it would be nice to replace the current definition
of CORE_ADDR with a struct and add functions to to do
operations like increment/decrement address. But the
assumption that the address space is flat and that you
can do arithmetic on addresses is pervasive.
