Speed Issues
« on: April 15, 2011, 07:08:05 AM »
I have been working on an interpreter for my own language lately and I am having some problems.

Its hilariously slow.
This block of code:
WHILE [v1<10000]
SETINTEGER v1 [v1+1]
WEND
Takes 1700 milliseconds at best.. :/

My point is, do Gan, Al or Mike have any tips for optimization?

My guess is you might have unnecessary loopage going on in the runtime as it looks for stuff to solve.
I had the same issue. I just took most of the stuff out of the runtime and put it to be processed before hand.

I think I'll post up my interpreter source later today but it'll probably be hard to decipher.

Yeh I figured I really just need to optimize the crap out of the preprocessor. At the moment all its doing is replacing variable names with indexes to memory locations so I don't have to do a lookup. I think it might be the massive amount of function calls that slow me down too.

I changed some things up and got the execution time down to about 790 ms. I also figured out the math parser is taking up 786 ms of that.. hmm..
