I want to write a machine target for GCC. But It requires that all the
registers GCC alloced in a basic block shall store its content to memory
before any branch or jump or function call. After the branch etc, the
memory data shall be reloaded into registers, no necessary the same one as
before.
Can this be implemented using target macros? If it can, what shall I
write to do such a thing?
