Just realised that this breaks bootstrap on arm-linux-gnueabihf.
I'd originally moved the zeroing of incorrect targets to
expand_expr_real_2, but then forgot why and undid it in the
name of going for the minimal fix. The reason is/was code like:
else if (target == 0)
op0 = convert_to_mode (mode, op0,
TYPE_UNSIGNED (TREE_TYPE
(treeop0)));
else
{
convert_move (target, op0,
TYPE_UNSIGNED (TREE_TYPE (treeop0)));
op0 = target;
}
where we could convert to the mode of the supplied target
instead of “mode”.
Testing a fix.
