[PATCH] D126461: [RISCV] Extract and store new vl of vleff iff destination isn't null

[Zakk Chen via Phabricator via cfe-commits]

khchen added a comment.

IMO, if I'm an user, I would not expected intrinsic function will generate the condition code to impact the performance, maybe we need to raise a issue in rvv-intrinsic-doc.

maybe another way is adding a note in intrinsic document to address that the vl could not be a null pointer.

How about the segment load? Does it make sense to add null pointer checking for all argument v0~vN?
