[PATCH v2 0/2] Enhanced VSTART and VL Checks for Vector Instructions

[Chao Liu <lc00631@tecorigin.com>]

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)).

PATCH v1:

Chao Liu (2):
  target/riscv: refactor VSTART_CHECK_EARLY_EXIT() to accept vl as a
    parameter
  target/riscv: fix handling of nop for vstart >= vl in some vector
    instruction
