[Qemu-devel] [PATCH v5 0/2] target/mips: Optimize MSA <ILVEV|ILVOD>.<B|H|W|D> instructions

[Mateja Marjanovic]

From: Mateja Marjanovic <address@hidden>

Optimize MSA instructions ILVEV.<B|H|W|D> and ILVOD.<B|H|W|D>,
using directly tcg registers and performing logic on
them insted of using helpers.

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 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 cover letter.
