For next release
^^^^^^^^^^^^^^^^
- optimize array1[index] += / -= array2[index] to not use slow stackeval (attemptAssignOptimizedBinexpr)
For next minor release
^^^^^^^^^^^^^^^^^^^^^^
...
For 9.0 major changes
^^^^^^^^^^^^^^^^^^^^^
- SEGMENTS.
- Add a mechanism to allocate variables into golden ram (or segments really) (see GoldenRam class)
- block "golden" treated specially: every var in here will be allocated in the Golden ram area
- that block can only contain variables.
- the variables can NOT have initialization values, they will all be set to zero on startup (simple memset)
- just initialize them yourself in start() if you need a non-zero value
- OR.... do all this automatically if 'golden' is enabled as a compiler option? So compiler allocates in ZP first, then Golden Ram, then regular ram
- OR.... make all this more generic and use some %segment option to create real segments for 64tass?
- (need separate step in codegen and IR to write the "golden" variables)
- rewrite 6502 codegen on Pt* ast and symboltable, instead of CompilerAst nodes. (work in codegen-on-new-ast branch)
- optimize "dotted string" comments again.
