It's not really UB, I've seen games do things like this before. Basically, all data processing instructions can now act as branch instructions, simply by having their dest be PC. Bowser's Inside Story on the DS for…
Anyway, I took the time to rewrite that paragraph a bit to be more respectful. :P Hopefully that'll come off better. The website take a few minutes to update.
Ah I miscommunicated, I still think PC can and should be used in places like the operand of an LDR / ADD. It's using it as the output of certain instructions (and allowing it to be used as such) that I take issue with.…
Hey, I'm the author, sorry it came off that way, I was really just poking fun. I should've definitely phrased that better! But no, I really think that making the program counter a GPR isn't a good design decision -…
The big issue is that it doesn't really need to be a GPR. You never find yourself using the PC in instructions other than in, say, the occasional add instruction for switch case jumptables, or pushes / pops. So it ends…
Better code, yeah I agree. It's way more easily understandable. At least for me though, 99% of my bash use is stuff that will never be seen by anyone else, so the simpler keystrokes one may prove useful. Maybe if I get…
Why D? Why not C / C++?
