I'm pretty sure it won't be called. That function converts a pointer to one address space into a pointer to a different address space. No such conversion is happening here. > where > is it defined? The function spu_addr_space_convert is the SPU-specific implementation of the target hook TARGET_ADDR_SPACE_CONVERT which is documented in the section on named address spaces. Ian
