Daedalus Further dynarec optimisation

July 26th, 2006, 02:00 Posted By: BrooksyX

Taken from http://strmnnrmn.blogspot.com/ :

Further dynarec optimisation

I've spent the last couple of evenings working on adding support for additional instructions to the dynamic recompiler. With every instruction I add, the generated code becomes a bit more efficient as I can avoid various bookeeping work (such as flushing all the cached registers out to memory.)

I've added code to handle the following ops:

* MULT, MULTU (multiply, multiply unsigned)

* DIV, DIVU (divide, divide unsigned)

* MFLO, MFHI (move from lo/hi)

* MTLO, MTHI (move to lo/hi)

* LB, LBU (load byte, load byte unsigned)

* LH, LHU (load halfword, load halfword unsigned)

So far I'm seeing around a 5-6% speedup with these changes (on top of the 10-12% speedup I talked about on Sunday). I am generating slightly more code as a result of this work, but given the large savings I made over the weekend this isn't much of an issue.

My next job is to look at optimising the remaining load/store instructions - I just have LWU/SB/SH to do (ignoring the 64 bit instructions for now). Once that's done I'm going to have a look at optimising sequences of load/store operations by caching the base address between uses. I think that should give a significant speed up for memory intensive chunks of code.
