ok.

me, I don't use C++ much myself.

one possible justification at this point is that it is doubtful I would
write a full C++ compiler, but C is simpler.

I am intending on writting my own open C++ compiler at some stage that you
can add language constructs and semantics too from the frontend. But first
I thought I should learn from the masters and port the existing GCC C++
frontend to C++, or at least see if it is possible.


C to C++ shouldn't be all that difficult (well, unless you are doing
something drastic, like trying to rework it to use OOP style or
somesuch...).

well, in my case I am mostly working off my script compiler as a base, every
so often getting around to working on it a little more (well, in my case, my
personal life, ... takes a higher priority than coding, so it is going
slow).

starting to work on modifying my compiler stage (from my script VM) to
output similar, but different, bytecode (main differences: C needs types,
everywhere, differences wrt opcode structure, jumps, ...).

in my case, for this compiler there will be no interpreter, rather it will
be JIT-only (the JIT being responsible for a lot of the low-level
optimizations). I eventually opted with making the bytecode focus on a stack
machine for simplicity reasons.

in some places I changed the workings of the bytecode for JIT-related
reasons (for example, all vars, labels, ... are now referenced
indirectly/symbolically, rather than with scope-indices, relative offsets,
....). this saves some on needing to regenerate this info.


or such...

or such ...


hmm...
