I imagine we are going to need a hook with asm > that makes sure none of the memory references are PC-relative. I guess since we cannot see which mnemonic is used in the inline asm, we ha= ve to be conservative and always reject pc-relative addresses with the "m" constraint (other constraints too?). Do we need to create a new memory constraint inline asm users can use to say pc-relative addresses are ok? How does x86 handle this?=
