Mode is an augmentation of SV behaviour. Some of these alterations are element-based (saturation), others involve post-analysis (predicate result) and others are Vector-based (mapreduce, fail-on-first).
-These are the modes:
+These are the modes for everything except [[sv/ldst]] and [[sv/branches]]:
* **normal** mode is straight vectorisation. no augmentations: the vector comprises an array of independently created results.
* **ffirst** or data-dependent fail-on-first: see separate section. the vector may be truncated depending on certain criteria.
