For next compiler release (7.6)
2021-10-19 21:38:07 +00:00
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2022-01-02 15:11:53 +00:00
- make it possible to inline non-asmsub routines that just contain a single statement (return, functioncall, assignment)
2022-01-01 13:08:36 +00:00

Need help with
^^^^^^^^^^^^^^
- c128 target: various machine specific things (free zp locations, how banking works, getting the floating point routines working, ...)
- other targets such as Atari 800XL: all required details about the machine, I have no clue whatsoever
2021-12-31 13:01:45 +00:00
- see the Porting Guide in the documentation for this.

Blocked by an official Commander-x16 r39 release
2021-11-13 11:56:59 +00:00
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2021-04-27 21:13:46 +00:00
- simplify cx16.joystick_get2() once this cx16 rom issue is resolved: https://github.com/commanderx16/x16-rom/issues/203
2021-12-30 18:05:56 +00:00
(I hope this will be included into the r39 roms when they get released)

Future
^^^^^^
2022-01-02 15:11:53 +00:00
- add pipe operator `` |> `` ?
2021-12-28 14:39:46 +00:00
- make it possible to use cpu opcodes such as 'nop' as variable names by prefixing all asm vars with something such as `` v_ ``
then we can get rid of the instruction lists in the machinedefinitions as well?
2021-11-06 18:09:33 +00:00
- fix the asm-labels problem (github issue #62)
2021-12-28 14:39:46 +00:00
- simplifyConditionalExpression() should not split expression if it still results in stack-based evaluation
2021-12-29 17:00:25 +00:00
- simplifyConditionalExpression() sometimes introduces needless assignment to r9 tempvar
2021-10-18 23:12:28 +00:00
- get rid of all TODO's in the code
2021-10-29 15:34:42 +00:00
- improve testability further, add more tests
2021-10-12 23:33:29 +00:00
- use more of Result<> and Either<> to handle errors/ nulls better
2021-12-28 14:39:46 +00:00
- 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.
2021-10-14 23:02:32 +00:00
- can we get rid of pieces of asmgen.AssignmentAsmGen by just reusing the AugmentableAssignment ? generated code should not suffer
2021-07-02 19:47:27 +00:00
- c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
2021-04-12 21:02:32 +00:00
- optimize several inner loops in gfx2 even further?
- add modes 2 and 3 to gfx2 (lowres 4 color and 16 color)?
2021-02-07 18:08:47 +00:00
- add a flood fill routine to gfx2?
2021-07-02 19:47:27 +00:00
- 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)?
2021-12-28 14:39:46 +00:00
- fix problems in c128 target
2021-07-02 19:47:27 +00:00
- [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 ...
2021-07-05 20:47:51 +00:00
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)

More code optimization ideas
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2021-12-31 13:01:45 +00:00
- if a for loop's loopvariable isn't referenced in the body, replace by a repeatloop
2021-12-29 17:00:25 +00:00
- automatically convert if statements that test for multiple values (if X==1 or X==2..) to if X in [1,2,..] statements, instead of just a warning
2021-12-09 20:13:13 +00:00
- byte typed expressions should be evaluated in the accumulator where possible, without (temp)var
for instance value = otherbyte >> 1 --> lda otherbite ; lsr a; sta value
2021-07-02 19:47:27 +00:00
- 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'
2021-12-06 20:43:17 +00:00
- this removes the need for the BinExprSplitter? (which is problematic and very limited now)
2021-11-21 13:00:19 +00:00
- introduce byte-index operator to avoid index multiplications in loops over arrays? see github issue #4
