It was not my intention to suggest to add BIAS here. This can
be done by the respective targets when/if they support mask_*, not
by you. What I meant is that I'm unsure whether to add a

Hi, Richi and Richard.
This patch is adding LEN_MASK_{GATHER_LOAD,SCATTER_STORE} to allow targets
handle flow control by mask and loop control by length on gather/scatter memory
operations. Consider this following case:
#include
void
f (uint8_t *restrict a,
uint8_t *rest
