Thanks to all who replied; the use case is returning a 64-bit value to a C function, which LE does by putting the top half in R0 and the bottom half in R15. Which is weird but is how it’s done. So I don’t much care about the top halves, nor bit 0 of the 32-bit register, but thanks for the concerns there!
