included. SVSTATE.MVL is not changed: only VL.
* **LRu**: Link Register Update. When set, Link Register will
only be updated if the Branch Condition succeeds. This avoids
- destruction of LR during loops.
+ destruction of LR during loops (particularly Vertical-First
+ ones).
* **BRc** Branch variant of Rc. Instructs svstep testing to overwrite
- the CR Field about to be tested
+ the CR Field about to be tested. Only takes effect in svstep mode
* **VSb** is most relevant for Vertical-First VLSET Mode. After testing,
if VSb is set, VL is truncated if the branch succeeds. If VSb is clear,
VL is truncated if the branch did **not** take place.
