This because on the first element an exception must be raised "as normal". * CR-based data-dependent ffirst on the other hand **can** set VL equal - to zero. This is the only means in the entirety of SV that VL may be set - to zero (with the exception of via the SV.STATE SPR). When VL is set + to zero. When VL is set zero due to the first element failing the CR bit-test, all subsequent vectorised operations are effectively `nops` which is *precisely the desired and intended behaviour*. -- 2.30.2
