...if-then-else hammocks in relevant regions (loops) right before the vectorizer kicks in. This part may require undoing, when an if-converted loop is not vectorized and the target does not support the resulting predicated scalar instructions. Hope this helps. Had the pleasure of working with the GCC autovect guys (or rather gals) from the start, before joining Nadav et al. recently.
