Fixes

• Corrected a bug in the m6809 assembler.

Release 2.7

Features

• Added a command-line option --allow-overflow to allow sign-overflows in pseudo-op assembly. For instance, `.byte -23, would not error if this option is set.
• Added a command-line option --Wcase-mismatch to warn user of symbol case mismatches.

Changes

• Subroutine calls succeeded immediately by a return instruction will issue a warning.
• Slightly improved error and warning syntax highlighting.

Fixes

• The --error option will now properly output errors to the specified file.
• Certain .Net exceptions were not properly caught in invalid assembly.
• .case directives were not evaluating string constants correctly.
• Fixed the ^^ (raise-to-the-power-of) operation.

Release 2.6.3.4

Changes

• Slightly improved the help text for the help command line options, and specific command line errors will now list instead of a generic error.

Fixes

• Fixed a bug in the format function that would error if it was not the sole expression.

Release 2.6.3.3

Changes

• Refactored the IEEE-754-to-CBM conversion routine to be slightly more efficient.

W65C02 would not report as a valid CPU mode. This is fixed.

Release 2.6.3.1

Added option --enable-branch-always to enable the bra mnemonic for 6502 mode.

Release 2.6.2.1

Features

• Added a sizeof function that returns the size in bytes of the given expression.

Changes

• Labels and instructions can now be parameterized in macro definitions.
• Option -f is a short alternative to --format.

Fixes

• Fixed an error when the output hash would not calculate correctly in certain cases with long addressing enabled.
• Creating config file from options was not naming all properties correctly. This is fixed.
• The help options -h and -? will no longer report being unknown in the help text.

Release 2.6.1.2

Features

• Added c64dtv2 CPU type

Fixes

• Adding uninitialized data past 64KiB in long addressing mode was not being handled properly. This has been fixed.

Release 2.6.1

Features

• Added labels-addresses-only option to refine label assembly output.
• Added long-addressing option to enable 24-bit (long) addressing. Output can exceed the 64KiB boundary when this option is enabled.

Changes

• Re-targeted the project to .Net 5. Source is still .Net Core 3.x (C# 8.0) compatible.
• Improved error output. Errors in source are now highlighted.
• Improved reporting of Z80 relative branching errors.
• Symbols inside macros are accessible when their expansions are labeled.
• By default, the .bank directive will no longer reset the Program Counter. To enable this behavior pass the --reset-pc-on-bank option.

Fixes

• Program overflow errors will now only occur after first pass.
• The .initmem directive will now properly initialize memory.
• Some errors were duplicating, particularly in loop constructions.

Release 2.5.2

Fixes

• Instructions without operands followed by colons should not throw errors (e.g., nop:nop)
• Fixed some 65816 and R65C02 instructions.
• Switching between Z80 and i8080 modes is now possible.
• Fixed ability for user-defined functions to change the values of passed parameters.
