- Determination for negative branches to local labels were one off which
meant lots of unnecessary local labels at end of long functions
- struse null/0-length check was reverse causing access to 0
- Removing some filters that pulled out relevant references from pointer
arrays
- Separating 6502 illegal opcodes (6502ill) and WDC specific 65C02
instructions (65C02WDC) from general disassembly
- invalid instructions will always be disassembled as dc.b $hh instead
of the non-assemblable instruction
- Changed how the instruction lookup is stored to more easily
distinguish between read-only and other instructions
- Added Atari 7800 labels (a78.lbl)
- Added a keyword "read" to declare a read-only version of a data label
to the labels file
- Fixes to determining addresses representing data or code
- Fixed missing data blocks that were exactly 16 bytes
- Allows jump tables without separating between each instruction
- Branch to instruction after jump instruction does not inject a
function separator
- Jump relative does not reference code
- More aggressive local labels
- Double checking code sections after detection phase
- Zero page instructions added to labels (65816 uses direct page and
will generate slightly off labels)
- Adding a labels file with all the c64 hardware addresses
- Labels are tracked outside of the binary file range
- Zero page tracking
- Improved code vs data tracking a bit
- Adding standard macros with for loops, memory copy, add, subtract,
move and set
- macros can be named with dots
- double negatives won't cause errors in expressions
- vice output will convert labels named "debugbreak" to vice breakpoints
rather than vice labels
- fixed issues with mixing conditional operators with math operators in
expressions
- struse.h replace with bookend didn't check bookends in all cases
- macros can be inside of conditionals (within if/else/endif, etc)
- string symbols mistake caused garbage code (missing braces around
assignment and return)
- rtl instruction had wrong opcode
- disassembler works a lot better with correct rtl, even for 6502
- disassembler can specify n bytes of data before code starts in src
mode (data=initial data size)
- String Symbols can be evaluated as expressions or assembled as code
- String Symbols can be generated by macros
- Cleaning up first page
- Adding more to the x65.txt documentation
- Started text documentation of assembler
- Built binary zip files (Windows)
- Fix for conditional + scope characters
- Fix for empty section "default" defaulting to BSS
- Using a section named DirectPage_Stack to adjust same named segment in
OMF file
- Resolving all zero page sections to fixed addresses before exporting
OMF
- Disassembler does more shenanigans to output more assemblable code
- Automatically determine the code address for c64 prg files
- x65dsasm now adds labels for internal referenced addresses
- x65dsasm has a src option that displays disassembly as code that could
assemble as is
- fixed the help output for dump_x65
- copied in struse.h
- Code and data segments are not just merged together, each segment in
each export group just gets address assigned and relocs / labels are
fixed up.
- BSS sections won't generate binary data if not inbetween code and data
segments for an export group (labels and relocs are still extended)
- DC directive now allows for .t (3 byte values) and .l (4 byte values)
decoration
- .lst includes all section info and address ranges if fixed
- Updated x65 dump tool with fixes to x65 data
- REPT caused a crash if expression was resolved after assembly
completed
- Fix expression % as a label at end of scope if another scope ended
before the current scope
- Removed # from conditionals since that doesn't fit with any assembler
style
- Added .l (long) and .t (triple) to label pool sizes, also supporting
.d as double which is the same size but different meaning than .w (word)
- XREF blocked linking with same name label
- REPT also works as a symbols for repeat counter to reduce need for
extra counting labels.
- "<<" got interpreted as a right shift
- Added LONG keyword to declare 32 bit values
- Each scope in a file shows the cycle count added up for instructions
within it.
- Added Merlin version of XREF which is EXT (was previously ignored)
- Added Merlin cycle counter on/off directive (CYC)
- XREF directive now required for referencing XDEF symbols from other
files
- Created cycle timing table for 6502, displaying for each line in .lst
files
- Map symbols might not have been updated with their labels
- Relocation index may be off
- Map symbols stored in 16 bits causing truncation of value in symbol
output
- Added a tool to dump the values in object files
- Fixed issue with CPU indexing
- Added missing 65816 jmp (addr,x) and jmp $123456,x and jsl
- Added a method for Merlin style linking to work in x65
- Made low byte / high byte (<, >) very low precedence
- Some more Merlin directives
- Split out some directive code from the huge ApplyDirective function
- Add source lines of keywords and labels to the output listing file
- x65 object file fixes
- added -acc=16 and -xy=16 command line options for 65816 immediate mode
instruction size
- added conditional expressions (evaluates to 0 for false and 1 for
true)
- fixed macro substitution to be whole word only
