... When I do a native code generator, I'll do that and throw all the optimising tricks at it, but as long as I'm treating the x86 as a simple stack machine,

I got my intel code generator working!

Graham Toal — Sat, 06 Jun 2009 14:40:00 GMT

It took about 2 days of programming and 2 days of debugging (one of which was Rainer's :-) ) to get an x86 code generator working for the toy compiler I wrote

... I've been doing something similar this week, and what I've learned is that in the x86 world, there are *many* different calling conventions. It looks like

... Very, very neat, Graham. I'd join you, but I'm currently working on porting a network stack and writing an operating system from the ground up. Seriously.

I don't think you've misunderstood the instructions. My suspicion is that nasm has mixed up the opcodes. Get it to show you the code listing to confirm. SETL

I'm working on signed arithmetic comparisons at the moment. I have a simple procedure that prints a signed number. It tests to see if the parameter is < 0,
