Subject: [PATCH v2] RISC-V: Fix RVV frm run test failure on RV32
From: Pan Li <pan2.li@intel.com<mailto:pan2.li@intel.com>>

Refine the run test case to avoid interactive checking in RV32, by
separating each checks in different functions.

gcc/testsuite/ChangeLog:

* gcc.target/riscv/rvv/base/float-point-frm-run-1.c: Fix run failure.
