--- Comment #12 from whitequark <whitequ...@whitequark.org> ---
I'm reopening this because the generated IR violates LLVM's own invariants,
which is clearly a problem. To quote LangRef for @llvm.memcpy: "The
‘llvm.memcpy.*‘ intrinsics copy a block of memory from the source location to
the destination location, which are not allowed to overlap."
