@ -37,7 +37,8 @@ What does Prog8 provide?
- small program boilerplate/compilersupport overhead
- programs can be run multiple times without reloading because of automatic variable (re)initializations.
- conditional branches
- 'when' statement to provide a concise jump table alternative to if/elseif chains
- ``when`` statement to provide a concise jump table alternative to if/elseif chains
- ``in`` expression for concise and efficient multi-value/containment check
- many built-in functions such as ``sin``, ``cos``, ``rnd``, ``abs``, ``min``, ``max``, ``sqrt``, ``msb``, ``rol``, ``ror``, ``swap``, ``sort`` and ``reverse``
- various powerful built-in libraries to do I/O, number conversions, graphics and more
- convenience abstractions for low level aspects such as ZeroPage handling, program startup, explicit memory addresses

- Subroutines with parameters and return values
- Complex nested expressions are possible
- Variables are allocated statically
- Conditional branches to map directly on processor branch instructions
- ``when`` statement to avoid if-else chains
- ``in`` expression for concise and efficient multi-value/containment test
- Nested subroutines can access variables from outer scopes to avoids the overhead to pass everything via parameters
- Variable data types include signed and unsigned bytes and words, arrays, strings.
- Floating point math also supported if the target system provides floating point library routines (C64 and Cx16 both do).

^^^^^^
- make some sort of "porting guide" with things required to support a new target platform
- 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?
- fix the asm-labels problem (github issue #62)
- make (an option) to let 64tass produce a listing file as well as output.
- simplifyConditionalExpression() should not split expression if it still results in stack-based evaluation
- simplifyConditionalExpression() sometimes introduces needless assignment to r9 tempvar
- get rid of all TODO's in the code

More code optimization ideas
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- 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
-
- 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
- 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'
