--- Comment #19 from Segher Boessenkool <segher at gcc dot gnu.org> --- We cannot allow "m" to allow pcrel memory accesses, because most existing inline assembler code will break then. So we then need some way to tell the compiler that some instruction *does* allow pcrel memory (or even *requires* it).
