}
- move vload() to cx16diskio module
- nameInAssemblyCode() should search smarter
- string.find should return index of found character + carry set if found, carry clear if not found. (fix cx16assem, it uses current behavior. Also fix docs!)
- if char in "string" should fall back to string.find if string is longer than... 16?
also.. is "string" removed from the interned strings?
- add option to memory() to get aligned memory block (word, page aligned)
- Typecastexpression.isSimple: make it 'expression.isSimple' rather than always false. (this breaks some things atm)
- IdentifierReference: fix equality to also include position. CallGraph can then also only store IdentifierRef instead of pair(ident, position) as keys.
- Fix: don't report as recursion if code assign address of its own subroutine to something, rather than calling it
- Fix: don't report as recursion if code assigns address of its own subroutine to something, rather than calling it
- allow "xxx" * constexpr (where constexpr is not a number literal, now gives expression error not same type)
- can we promise a left-to-right function call argument evaluation? without sacrificing performance
- unify FunctioncallExpression + FunctioncallStatement and PipeExpression + Pipe statement, may require moving Expression/Statement into interfaces instead of abstract base classes
@ -43,8 +43,7 @@ Future Things and Ideas
- simplifyConditionalExpression() should not split expression if it still results in stack-based evaluation
- simplifyConditionalExpression() sometimes introduces needless assignment to r9 tempvar
- consider adding McCarthy evaluation to shortcircuit and and or expressions. First do ifs by splitting them up? Then do expressions that compute a value?
- improve testability further, add more tests
- use more of Result<> and Either<> to handle errors/ nulls better
- use more of Result<> and Either<> to handle errors/ nulls better?
- rethink the whole "isAugmentable" business. Because the way this is determined, should always also be exactly mirrorred in the AugmentableAssignmentAsmGen or you'll get a crash at code gen time.
- can we get rid of pieces of asmgen.AssignmentAsmGen by just reusing the AugmentableAssignment ? generated code should not suffer
- c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
