[PATCH v1 0/4] Support RVV register overlap for vwadd[u].vv

From: Pan Li <[email protected]>

Like v[sz]ext.vf8, we continue the support for vwadd[u].vv.

The below test suites are passed for this patch:
1. The rv64gcv fully regression tests.

Pan Li (4):
  RISC-V: Allow RVV register overlap for vw{add,sub,mul}[u].vv
  RISC-V: Add test cases for vwadd.vv reg overlap
  RISC-V: Add test cases for vwaddu.vv reg overlap
  RISC-V: Add one more test case for vwadd.vv
