- Structs can contain empty lines
- Structs can be empty
- All structs have a size member named bytes, the number of bytes used
by a struct is <struct>.bytes
- graph command line option adds a calling graph to the disassembly file
- graph+bra includes branches in the calling graph
- re-evaluating separating code/data segments after the segments have
been culled.
- Added a c64kernal.lbl file that includes kernal calls
- If an address is unreachable it is data even if a branch crosses
- If a branch crosses data then that branch can be valid code
- If a segment is initially considered code but not reachable after all
is said and done it is reverted to data
- 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)
