 Known Problems
-- (incd020.kc) Increment/decrement of value pointed to by pointer does not work. eg. byte* BGCOL = $d020; (*BGCOL)++;
 - (inlinearrayproblem.kc) Arrays / strings allocated inline destroy functions (because they are allocated where the call enters.
 - (forincrementassign.kc) Classic for() does not allow assignment as increment, eg. for(byte i=0;i<25;i=i+2) {}
 - (forrangesymbolic.kc) Range-based for does not recognize symbolic constants. The following gives a ParseTreeConstantEvaluator$NotConstantException - const byte* BITMAP = $2000; for(byte* b : BITMAP..BITMAP+$2000) { *b = 0; }

 - Improve locality of block sequence for if(cond) { stmt1; } else { stmt2; } to if(!cond) goto @else stmt1; jmp @end; @else: stmt2; @end:
 - Optimize if/else by swapping if & else if cond is easier to evaluate than !cond.
 - Let { stmt } and for() {} introduce a new anonymous scope. (But not when optimizing)
-- Add preprocessing / find a way to allow some functions to run at compile time. This will always be to initialize memory to a certain state.
-  - Syntax: A preprocess keyword usable before initializers or global statements blocks? (maybe compiletime is a better word as it is not a preprocessor in the C-sense of the word)
-  - byte[$100] sins = preprocess { [x] = sin(2.0*PI*x/$100) };
-  - byte[$100] sins; preprocess { for(byte x : 0 $ff) { sins[x] = sin(2.0*PI*x/$100)}};
 - Implement inline compilation of functions (and a mechanism for choosing which methods / calls to inline)
 - Handle long branches
 - Optimize loops by unrolling them somewhat
 - Optimize loops with Strength reduction (https://en.wikipedia.org/wiki/Strength_reduction)
-- Support calculated pointers eg. *(ptr+i)
 - Add syntax for encoded chars (eg. PETSCII instead of SCREEN)

+Pointers
+- Support calculated pointers eg. *(ptr+i)
+- Use a rule-based approach should de-inline most pointer derefs again just before register allocation. ( *a = *b + *c => $1=*b (reg a), $2=*c (alu), $3=$1+$2 (reg a), *a = $3  - but *a=*a+const should stay inlined as it has efficient ASM)
+- Change pointer derefs ASM signature to _deref_xxx (from _star_xxx)
+- VariableReplacer, GraphReplacer, Pass1GenerateSSA#versionAllUses() has a pretty ugly handling of pointers. Abstract prettier code.
+- AsmFragmentManager only handles _neq_ pointer comparison. Abstract a better replacer and handle the rest.
+- Consider if array-indexing should be handled in the same way as unary * when generating statements (put into inline Pointers instead of temporary variables.) This will fix a[2]++, which probably does not work atm.
+
+Compiletime (Preprocessing)
+- Add preprocessing / find a way to allow some functions to run at compile time. This will always be to initialize memory to a certain state.
+  - Syntax: A compiletime keyword usable before initializers or global statements blocks? (compiletime is a better word as it is not a preprocessor in the C-sense of the word)

 Imports
+- Remove unused functions & symbols.
 - Add imports
-- Remove unused functions.
 - Add an export keyword ensuring that a function is generated even if it is never called. Maybe export can be handled by generating a call that can be used as stub.
