Hi, all: In the second version of this patch, I addressed the issue that other vector instructions didn't check for vstart >= vl correctly.
I refactored the VSTART_CHECK_EARLY_EXIT() macro. This change is intended to: Vector instructions with special vl values can also be checked with this macro, such as vlm.v instruction (real vl = ceil(vl / 8)).
