This is looking very nice! I want to switch from D1 to D2, but...
I don't want to sound greedy or anything, and I know others have asked
for this before, but is making a 64-bit Linux version of DMD a lot of work?
I admit I don't know much about these things, and what I'm going to say
next may not make sense at all, but here goes:
x86-64 is just a superset of x86, right? Wouldn't it be possible, as a
first step in the direction of a full-fledged x86-64 compiler, to simply
make one that uses the same instruction set as the current DMD, but, I
dunno, marks the executable as 64-bit (or something like that)?
Specialisation and optimisation for the 64-bit architecture could then
come at a later point in time.
It's not quite that simple. It's not a full superset; some x86 instructions are
not valid x86-64 instructions.
For example, I think 'inc' was removed to make place for prefixes that set some
flags for the next instruction and allow it to use the extra registers r8-r15.
