Axe: Hex or Mnemonics?
« on: May 25, 2011, 05:11:51 pm »
I was wondering, @Quigibo, if after the parser reading the text it will convert it to mnemonics or hex, or maybe this is a stupid question, but I'm pretty sure you have like for "ClrDraw" you have like EF7450.

So I was wondering, do you convert stuff directly to hex or do you have an assembler inside Axe?

Its direct to machine code.  Although sometimes, its slightly indirect with placeholders that get filled in later, but usually its direct.  And its not a stupid question, most computer compilers actually DO do that.  I would have in Axe too if there was enough memory, but unfortunately there isn't.

That's actually great news. Thus the compiling is much faster, I guess.

What's the advantage to converting it to mnemonics first?

Its way easier to make the compiler (assuming you already have a working assembler) and it allows you to hand optimize the code really easily if you want to since you can get an assembly output.  But Mimas wasn't around at the time I started Axe so that wasn't an option back then.

It also makes the compiler more portable, since you can change assemblers for different systems and most assemblers use similar syntax.
