Hello,
I hadn't implemented this simplification because I think it is invalid code,
but apparently people do write it, so we might as well handle it sensibly.
This also happens to work around PR 83104 (already fixed).
bootstrap+regtest on powerpc64le-unknown-linux-gnu.
Ok.
What about 0 - ptr? (ok, that's even more weird)
I thought about it, but it seemed less likely (I can imagine the idiom
ptr-0 being used to let the compiler guess the right type). I'll add 0-ptr
if you think that may be useful.
