: I am baffled. How can a compiler allocate global registers?
: The only solution that comes to my mind is to make the linker
: not only capable of resolving memory addresses, but also
: inserting load/store instructions in case of global register
: conflicts. But that would undo compiler optimisation.
: ...


I remember reading somewhere that the MIPS linkers get as input
some kind of intermediate language form (not regular object files),
thus enabling them to do various inter-procedural optimizations
such as inter-procedural register allocation.
