## answers to 2, RM Modes
-Normal Mode:
+**Normal Mode:**
* simple mode is straight vectorisation.
* reduce mode
simple mode is fine including on predication but has a CHANGE OF BEHAVIOUR. first bit of src/dest is used when zeroing is on, but first ENABLED bit of predicate is used when VL>1.
-reduce mode is unaffected (meaningless)
+reduce mode is unaffected (meaningless) on a scalar operation
-## answers to 4, loops
+fail-first with or without VLI, should be unaffected, but what should VL be truncated to? the override VL=1? (or VL=0 when VLI is set?)
+
+saturation mode is fine
+
+predicate-result should be fine as well.
