For next minor release
^^^^^^^^^^^^^^^^^^^^^^
- fix hasInitValue() and isBssVar()
- BSS.
64tass can put variables into a section with .section BSS <variable> .send BSS
and then putting .dsection BSS where it should output the BSS
Define vars in BSS with .fill rather than .byte otherwise they STILL take up space!
- BSS in 6502 codegen: create BSS section in output assembly code and put StStaticVariables in there with bss=true.
Don't forget to add init code to zero out everything that was put in bss. If array in bss->only zero ONCE if possible.
Note that bss can still contain variables that have @zp tag and those are already dealt with differently
- BSS: subroutine parameters don't have to be set to 0.
Note that 'bss' can still be true for variables that were moved into zeropage, so have to check that!
- BSS subroutine parameters don't have to be set to 0.
- when putting BSS in specific memory block ($a000-$bfff, $c000-$cfff) add a .cerror check for overflow!
