@ -512,6 +512,10 @@ better to sink the picbase computation down into the block for the
assertion, as it is the only one that uses it. This happens for a lot of
code with early outs.
Another example is loads of arguments, which are usually emitted into the
entry block on targets like x86. If not used in all paths through a
function, they should be sunk into the ones that do.
In this case, whole-function-isel would also handle this.
