r2625 (2021-04-25)
==================
The last release got more than a year old now and there were
plenty of pending corrections to be released. Some planned
features still didn't made it in. Maybe next time.
**Fixes**
* .fill/.align multi byte pattern fix
Broke due to changes in r1845.
* Wrong diagnostic for incomplete byte string
The missing closing quote was pointed at the wrong place
* Incomplete diagnostic message
The opcode was not displayed in some cases
* Diagnostic locations fixed
In some cases the location was wrong
* Duplicate diagnostic messages avoided
In some cases redundant diagnostics was output
* Crash while .function declaration and macro init parameters
Found by Pierre
* Improved filename portability checks
In some cases case insensitive filenames were not recognized
* Diagnostics of non-portable filename characters improved
Now points at the problematic character.
* Functions did not execute as loop and other conditions
Now they do.
* Can't calculate errors related to functions
In some cases these were incorrectly reported
* 4510 missed had () instead of (),z addressing mode
Now same as 65CE02 in this regard
* Improved format() diagnostics
It's more strict now
* Floating point bitops didn't work as intended
Actually in some cases they did work but mostly not
* Dot eor operator works again in TASM compatible mode
Got broken due to syntax clash with hexadecimal floats
* Wrong message text for invalid unary operators
Tried to diagnose them like binary by mistake
* Improved syntax highlighting
In some case it didn't highlight well on vim
* Byte string compare didn't work properly
In case a byte string was inverted.
* In some cases .null failed to detect zeros
For example for ~$ff
**Changes**
* Comment nesting
Directives are not recognized now in commented block
* Negative size an error now, size extension a warning
If an offset reduces a memory area beyond 0 it's a fault now
(instead of 0) and extension beyond the original size a warning.
Controllable through -Wsize-large.
* PC bank wrapping gone now
Seemed like a good idea but crossing banks with long data gave
unexpected results for many people.
* VICE label de-duplication is gone now
Was intended to avoid warnings on import but actually breaks
symbolic breakpoints if the needed label gets deduplicated...
* -Wswitch-case gone now
Could cause unexpected side effects which is a no-no for diagnostics
* Ident renamed to symbol
For less confusing diagnostic messages
* Long values not displayed in listing by default
They cluttered up the listing. They are still displayed in verbose
mode.
* Dictionary keys must be identical and not equal
Otherwise bit strings can't be matched properly for example.
* Hex float format from format() gone now
Seemed like it's easy to add without much effort but it was not cross
platform.
* Bit string extraction operators now return bit string
Did return bytes for a long while but now I realized those may not
compare as expected in some cases.
* Multi line expressions are gone now
Seemed like a good idea back then but they cause more problems than
they solve. They were never documented due to all the unsolved edge
cases anyway.
* Duplicated label files do not append automatically
It must be done now explicitly with --labels-append
* Unnamed values not listed in listing any more
There's no label so makes no sense
**New**
* Immediate operand to branches
It's now possible to write 'bne #0' (for self modifying code)
* Hexadecimal byte string literal separation with spaces
Space is accepted now in hexadecimal byte strings like x'ab cd'
* Various byte string functions added
Like byte(), word() and friends
* New --output-append parameter
For appending the output to a file instead of overwriting it
* New --no-output option
For cases where no output file is needed
* Symbol definition syntax
May be defined with a dot prefix. Useful as dictionary keys.
* New .sfunction directive
For defining single line functions which only do calculations
* Alternative end directives
Bit more verbose but more consistent and easier to remember.
E.g. .endpage vs. .endp
* Identity operator (===)
For exact matching
* --no-error and --error-append
To not save or append error messages
* Broadcasting conditional operator is '??'
Sometimes broadcasting is needed but that's not compatible with the
regular '?' conditional operator
* Diagnostics for interrupted compilation
Now it's displayed where it happened for improved infinite loop
debugging.
* --labels-append
For appending to label files. |
