From: Mateja Marjanovic <mateja.marjano...@rt-rk.com> Optimize MSA instructions ILVEV.<B|H|W|D>, ILVOD.<B|H|W|D>, ILVL.<B|H|W|D> and ILVR.<B|H|W|D> using the hybrid approach, MSA helpers in some cases and directly tcg registers in other cases, so the performance would be better.
v6: - Add ILVL.<B|H|W|D> and ILVR.<B|H|W|D> MSA instructions with mixed approaches (with helpers and with tcg registers). - Test the performance for ILVL.<B|H|W|D> and ILVR.<B|H|W|D> MSA instructions, with helpers, with tcg and with the mixed approach. - Use a tcg register instead of an int variable for storing a constant value of the mask (for logic operations). - Eliminate some unnecessary tcg_gen calls. - Changes in commit messages and the cover letter. v5: - Use tcg_gen_deposit function. - Added performance number for no-deposit and with-deposit cases of ILVEV.W. - Minor changes in commit messages and the cover letter. v4: - Clean up typing errors. - Change the commit message and the cover letter. - Fix bug for ILVEV.D, in case where the destination and one of the sources are the same register. v3: - Reduce the number of logic operations to a minimum. - Add comments. v2: - Minor changes in commit messages and the cover letter.
