TODO
|
|
====
|
|
|
|
For next compiler release (7.4)
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
BUG: fix "assignment isAugmented correctness" test
|
|
|
|
optimize TODO in "Add assignment to initialize with zero" in StatementReorderer
|
|
optimize TODO in after(assignment) in VariousCleanups
|
|
optimize: add some more constant folders mentioned in test.p8
|
|
optimize: there is an optimizations in AsmOptimizer that can only be done correctly
|
|
if it knows about regular ram vs io space ram distinction.
|
|
|
|
|
|
Blocked by an official Commander-x16 v39 release
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
- simplify cx16.joystick_get2() once this cx16 rom issue is resolved: https://github.com/commanderx16/x16-rom/issues/203
|
|
(I hope this will still be included into the final v39 roms release for the cx16)
|
|
|
|
|
|
Future
|
|
^^^^^^
|
|
- use UByte instead of Short
|
|
- simplifyConditionalExpression() should not split expression if it still results in stack-based evaluation
|
|
- remove special code generation for while and util expression
|
|
by rewriting while and until expressions into if+jump (consider them syntactic sugar)
|
|
but the result should not produce larger code ofcourse!
|
|
- while-expression should now also get the simplifyConditionalExpression() treatment
|
|
- fix the asm-labels problem (github issue #62)
|
|
- find a way to optimize asm-subroutine param passing where it now sometimes uses the evalstack?
|
|
- find a way to let registerArgsViaStackEvaluation not use the stack anymore
|
|
- document the various compiler command line options in more detail. See "Compiling program code" in the docs
|
|
- get rid of all TODO's in the code
|
|
- improve testability further, add more tests
|
|
- replace certain uses of inferredType.getOr(DataType.UNDEFINED) by i.getOrElse({ errorhandler })
|
|
- see if we can remove more "[InferredType].getOr(DataType.UNDEFINED)"
|
|
- use more of Result<> and Either<> to handle errors/ nulls better
|
|
- 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)
|
|
- optimize several inner loops in gfx2 even further?
|
|
- add modes 2 and 3 to gfx2 (lowres 4 color and 16 color)?
|
|
- add a flood fill routine to gfx2?
|
|
- add a diskio.f_seek() routine for the Cx16 that uses its seek dos api?
|
|
- make it possible for diskio to read and write from more than one file at the same time (= use multiple io channels)?
|
|
- make it possible to use cpu opcodes such as 'nop' as variable names by prefixing all asm vars with something such as ``v_``
|
|
- [problematic due to 64tass:] add a compiler option to not remove unused subroutines. this allows for building library programs. But this won't work with 64tass's .proc ...
|
|
Perhaps replace all uses of .proc/.pend by .block/.bend will fix that?
|
|
(but we lose the optimizing aspect of the assembler where it strips out unused code.
|
|
There's not really a dynamic switch possible as all assembly lib code is static and uses one or the other)
|
|
- introduce byte-index operator to avoid index multiplications in loops over arrays? see github issue #4
|
|
|
|
|
|
More code optimization ideas
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
- detect variables that are written but never read - mark those as unused too and remove them, such as ``uword unused = memory("unused222", 20)`` - also remove this memory slab allocation
|
|
- rewrite expression tree evaluation such that it doesn't use an eval stack but flatten the tree into linear code that uses a fixed number of predetermined value 'variables'
|
|
- this removes the need for the BinExprSplitter (which is problematic now)
