Hi,

I would try using the named address space for your issue (see
TARGET_ADDR_SPACE_POINTER_MODE). Please check the SPU target for an
implementation example.

Hummm, I haven't noticed this hook before. Could this be used to implement cases where function pointers have a different size than data pointers (as in harvard archs). It looks like it but can someone confirm?

Cheers,
