Improving script memory usage

Hi.  Just a heads up to let everyone know that I'm finally working on OpenBOR again.  I ran a test yesterday, and found that about 50% of instructions in most compiled scripts are no-ops that just indicate things to the compiler and do nothing during execution.

I'm planning to try implementing an optimization to remove these instructions after compilation, which should be a major improvement to script memory usage.  It's nowhere near as simple as it sounds, though, so no promises about if or when it'll be done. :)
 
Long time no see and back with good news more memory is always a good thing look forward to this update.
 
Thanks, everyone!

It's not what I was talking about earlier, but I stumbled across a different and much easier optimization opportunity while I was looking through the code, and committed it.  So even without the larger changes I'm working on, script memory usage should be reduced by maybe 3-6% already by r4077. :)

Though that probably won't make a big difference for most people, since script is a fairly small percentage of total memory usage in most mods.
 
Great to see you again, Plombo. ;D It's been so long. It would be great to see the memory being improved in OpenBOR.
 
I think I've got it working now.  I'm going to test some more, then I might make a thread asking people to test the memory savings and confirm I didn't break anything. :)
 
WB Plombo!

I've been using build 4077 without any problems.

What's the best way to test the memory savings?  I'm just going by what is loaded to memory on first run.
