Test failures in Vector Permutation Arithmetic Instructions

Last updated: November 21, 2022

Description:

Tests for the unit testing have been added and necessary environment changes have been made to run the tests on Spike and ARA. Following tests are found to be failing on the RTL. The tests can be verified by running on Spike using the usual Make targets in ara/apps (usingmake riscv_tests_spike)

In this issue, vector permutation instructions related failure have been reported. Other tests are also available. Each of these combination is a test file in ara/apps/riscv-tests/isa/rv64uv/ and is also listed in its Makefrag.
