Hello,
What would be the recommended way to model variables that are allocated
to different address spaces?
Can you describe the architecture a bit?
I found DW_OPT_xderef for dereferencing address-space qualified pointers
but the resulting memory location description wouldn’t have an
address-space qualifier.
DW_OPT_xderef translates from an architecturally defined memory
reference including an address space into a linear address space
(generic type). DWARF doesn't support computations on address-space
qualified addresses, although using a typed stack, this could be an
extension.
I found DW_AT_address_class, which allows attaching an integer, which
could represent the address-space. This sounds pretty close. I’m a bit
thrown off by the example, though.
Which example?
