From 2f077842f2b356a086f70e54c831be53c6f0e101 Mon Sep 17 00:00:00 2001 From: Max Chou Date: Thu, 19 Sep 2024 01:14:07 +0800 Subject: target/riscv: rvv: Replace VSTART_CHECK_EARLY_EXIT in vext_ldst_us Because the real vl (evl) of vext_ldst_us may be different (e.g. vlm.v/vsm.v/etc.), so the VSTART_CHECK_EARLY_EXIT checking function should be replaced by checking evl in vext_ldst_us.
