# Change log ## Current version * Preliminary experimental Game Boy support. * Preliminary MSX support. * Super experimental and very incomplete Intel 8086 support via 8080-to-8086 translation. * Support for Intel 8085, together with illegal instructions. * More label file formats. * Added `memory_barrier` macro. * Added `random` module. * Added `ensure_mixedcase` function and `oldpet` and `origpet` text encodings. * Added `MILLFORK_VERSION` preprocessor parameter. * Added structs and unions. * Added unsigned byte division and modulo. * Pointers can now be allocated anywhere. * Pointers can now be typed. * Added `nullptr`. * You can now take a pointer to a stack variable. * Arrays can now have elements of types other than `byte` (still limited in size to 1 byte though) and be built out of struct literals. * Arrays can now be constant. * Added hint for identifiers with typos. * Aliases now also support subfields. * Short functions can be now defined using expression syntax. * 6502: Fixed optimizations using index registers. * 6502: Fixed optimizations of comparisons. * Preprocessor: Added `#use A=B` directive * Preprocessor: Added `if` function * Fixed volatile-related bugs. * Fixed optimizations removing jumps to jumps. * Fixed optimizations removing pointless stores to local variables. * Fixed name clashes when passing parameters to functions and macros. * Fixed `#use` not accessing all preprocessor parameters. * Fixed `#pragma` not respecting `#if`. * Fixed `@long` and `@long_be` array filters. * 8080 and LR35902: fixed large stack variables. * Other bug fixes. * Optimization improvements. ## 0.3.2 * Almost complete support for the Zilog Z80, Intel 8080 and Sharp LR35902 microprocessors. * A very incomplete support for NEC PC-88, ZX Spectrum, CP/M and Amstrad CPC. * Unified the syntax of commandline switches. * Automatic detection of the standard include path. * Added aliases. * Added enumeration types. * Added preprocessor. * Added `for` loops over enum types and in-place lists * Added `align` keyword for choosing data and code alignment. * Added original line numbers in assembler output. * Added `sizeof` operator. * Added preliminary support for `volatile` keyword. * Added multiplication of a 16-bit number by an unsigned 8-bit number. * Added more warnings. * Automatic selection of text encoding based on target platform. * Text literals can be now used as expressions of type `pointer`. * Extra `z` at the name of the encoding means that the string is zero-terminated. * **Potentially breaking change!** No longer allowed to define things with names that are keywords or builtins. * **Potentially breaking change!** Curly braces in text literals are now used for escape sequences. * **Potentially breaking change!** Changed the `c64_basic` module. * **Potentially breaking change!** `scr` now refers to the default screencodes as defined for the platform. Code that uses both a custom platform definition and the `scr` encoding needs attention (either change `scr` to `petscr` or add `screen_encoding=petscr` in the platform definition file). * **Potentially breaking change!** Platform definitions now need appropriate feature definitions. Code that uses a custom platform definitions will cause extra warnings until fixed. * Software variable stack for 6502. * Other optimizations and fixes for stack variables. * Various code deduplication optimizations. * Fixed emitting constant decimal expressions. * Fixed decimal subtraction. * Fixed signed comparison. * Fixed `for`...`downto` loops. * Fixed invalid optimization of loads before `BEQ` and similar * Fixed miscompiled `nonet` calls. * Parser performance improvement. * Standard libraries improvements. * Other improvements. ## 0.3.0 * Finally faster than C. * Licenced the standard library more permissively. * Preliminary Atari 2600, BBC Micro and LUnix support. * Added array initialization syntax with `for`. * Added multiple new text codecs. * Added character literals. * Added 24-bit `farword` type. * Special array layouts, e.g. `@word`. * Fixed invalid offsets for branching instructions. * Fixed incorrectly overlapping local variables. * Fixed broken `downto` loops. * Fixed broken comparisons between variables of different sizes. * Fixed several other bugs. * Tons of optimizer improvements. * Other improvements. ## 0.2.2 * Allowed adding constant words to variable bytes without the zeropage pseudoregister. * `-fzp-register` is now enabled by default, as the documentation has already been saying. * Allowed more kinds of constants within variable and array initializers. * Fixed several bugs. * Other improvements. ## 0.2 * **Breaking change!** Renamed `inline` to `macro`. * **Breaking change!** Added support for memory segments. Changed the platform definition file syntax. * Added preliminary support for 65CE02, HuC6280 and 65816 processors. * Added support for Famicom/NES and C64 with SuperCPU. * Added new `-O1` optimization preset; old `-O1` became `-O2`, old `-O2` became `-O3` and so on. * Added command line options for controlling the size-speed trade-offs. * Added support for parameters for macros written in Millfork. * Enabled calling macros with index expression parameters. * Enabled calling macros from assembly. * Added optimizer hints: `inline`, `noinline`, `register`. * Added command line flags `--size`, `--fast`, `--blast-processing`. * Removed command line flag `--detailed-flow`. Detailed flow analysis was slow, broken, hard to maintain, and didn't even help that much. * Added `*'=`, `nonet`, `hi` and `lo` operators. * Added support for zeropage pseudoregisters, allowing for some operators work with more types of operands. * Added return dispatch statements. * Added `break` and `continue` statements. * Allowed the `else if` combination (i.e. the `else` branch doesn't have to be in braces if it's just a single `if`-`else` statement). * Added octal and quaternary literals. * Fixed several allocation bugs. * Fixed several optimization bugs. * Fixed several C64 and C16 library bugs. * Fixed several other bugs. * Other improvements. ## 0.1 * Initial numbered version.
