For next compiler release (7.2)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

|
* FIX CRASH BUG *
|
|
when compiling petaxian: (attack.p8)
|
|
Exception in thread "main" prog8.ast.base.FatalAstException: vardecls for variables, with initial numerical value, should have been rewritten as plain vardecl + assignment VarDecl(name=attack_num, vartype=VAR, datatype=UBYTE, value=DirectMemoryRead([IdentifierRef([eRef]) + NumericLiteral(UWORD:11)]), pos=[attack.p8: line 72 col 5-45])

- analyze (and fix?): TODO why are these bigger now than before the var-initializer optimization:
|
|
; cube3d-float (THIS ONE IS A LOT BIGGER!!)
|
|
|
|
- fix the asm-labels problem (github issue #62)
|
|
- find a way to optimize asm-subroutine param passing where it now sometimes uses the evalstack?
|
|
|
|
|

Blocked by 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
|
|
^^^^^^
|
|
- 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
|
|
- [complicated] find a way to optimize if-statement codegen so that "if var & %10000" doesn't use evalstack & subroutine call, but also that the simple case "if X {...}" remains fast
|
|
- 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)
