Continued work on 64-bit shifts. - Improved 64-bit shifts without NEON (should benefit all cases). - Fixed bugs in constant shift code. - Rewrote 64-bit neon patch to take advantage of the new non-neon code, in the fall-back case. - Titied up the code, in general. - Rewrote SImode shift amount patch for new neon patches. The code produced now seems pretty good, but it still seems to choose which mode to use slightly haphazardly. The next step is to figure that out and benchmark the results.
Had a few more attempts at getting the LAVA system to do something useful for me. I'm getting closer, but keep hitting new problems. Some of them my fault, and some are bugs in the system. Paul Larson has been very kindly helping me out and swatting the bugs.
Didn't get much further with benchmarking for the generic tuning. This has been put on the back-burner while I work on the Neon shifts, and my test runs on my IGEPv2 A8 board have all been interrupted by power cuts or rendered useless by my forgetting to kill background tasks (such as Xorg).
