3 ; The main purpose of this test is to find out whether copyPhysReg can deal with
4 ; the memmove-like situation arising in tuples, where an early copy can clobber
5 ; the value needed by a later one if the tuples overlap.
7 ; We use dummy inline asm to force LLVM to generate a COPY between the registers
8 ; we want by clobbering all the others.
