Hi Scott, Well, I'm interested mainly in the 12-bit PIC architecture. I know that T. Scott Dattalo has worked on the 14- and 16-bit architectures, however I'm not sure he's still actively developing. Also, he's added further complication by adding pCode on top of iCode, so it's not like it would be any easier to understand :/
What gets me is that looking at the different back ends, they all seem to have a main, a register allocation, and a generator. Many pieces of each back end look almost the same, but with some differences that are hard for me to make sense out of, since I'm not even sure what the common portions are supposed to do. I have some vague ideas about some pieces, such as the asmop set of functions which generate assembly code for operands, but I'm not even sure how that relates to the register allocation, or how the whole contraption determines what symbols are spillable, rematerializable, and so on. --Rob On Dec 11, 2006, at 8:18 PM, Scott Finneran wrote: > Hi Robert, > > I am afraid that I can't help you with a rough guide.
