error: internal compiler error: src/librustc_trans/mir/operand.rs:111: not immediate: OperandRef(Ref((%D32x4*:  %_7 = alloca %D32x4), AbiAligned) @ D32x4)

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: run with `RUST_BACKTRACE=1` for a backtrace
