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