Z88dk v1.99A – Cross-platform development environment (http://www.octoate.de/wp/2015/12/24/z88dk-v1-99a-cross-platform-development-environment/?pk_campaign=feed&pk_kwd=z88dk-v1-99a-cross-platform-development-environment)
24 December 2015, 10:30 amA new version of the Z88dk development environment for Z80 based computer (e.g. Amstrad CPC, Cambridge Z88, MSX, Sinclair ZX 81, Sinclair ZX Spectrum, etc.) was just released. The release is a transition release on the way to v2.0 which aims on using the SDCC (http://www.octoate.de/wp/2015/06/27/2809/) compiler instead of the Small-C compiler, which was used before. This leads to much faster and smaller output binaries. You can choose between using the Small-C compiler with the old and the new C library or use the SDCC compiler with the new C library. The new C library also introduces full C standard compliance to Z88dk.
The newest version can be downloaded from the Z88dk homepage (http://www.z88dk.org).
(Brief) Changelog:- [z80asm] Sections have been introduced for generating memory maps and compiling to bankswitched memory.
- [z80asm] Modern logical operators have been adopted.
- [z80asm] New scoping keywords PUBLIC, EXTERN and GLOBAL introduced.
- [z80asm] Relocate files are generated for output binaries for patching assembled code to a new address at load time.
- [sccz80] Numerous bugfixes.
- [sdcc] SDCC is now fully supported as alternate C compiler for the new C library.
- [sdcc] SDCC’s generated code is improved by a large set of aggressive peephole rules (use -SO3 to enable).
- [sdcc] SDCC’s calls to its primitive functions are modified to use callee linkage.
- [new c lib] New C library written in assembly language from scratch aiming for a subset of C11 compliance. Contains more than 700 functions currently.
- [new c lib] Stdio made object-oriented so that drivers can inherit library code to implement features with a minimal amount of additional code.
- [new c lib] Stdio base classes currently include serial character i/o and terminal i/o implementing windows and proportional fonts. Disk i/o is missing in this release.
- [new c lib] Unique stdio implementation allows removal of high level buffers without affecting performance.
- [new c lib] Many functions from GNU and POSIX are present beyond the C11 standard.
- [new c lib] Many unique libraries including some C++ STL containers, data compression, obstacks, game libraries, sound, fzx proportional fonts, etc. The new C lib contains libraries not present in the classic C lib and vice versa. Over time the two libraries will homogenize.
- [new c lib] CRTs are supplied for three initial targets: embedded (generic z80), cpm, zx (zx spectrum). Specialized crts allow immediate compilation without customization by the user.
- [new c lib] The library and crts are highly configurable at library build time and at compile time. Options allow easy generation of binaries for ROM or RAM targets.
- [tools] New tool ticks is a command line z80 emulator able to exactly measure execution time of a code block.
- [tools] New tool dzx7 is a decompressor counterpart to zx7.
- [tools] New tool zx7 is an optimal lz77/lzss data compressor with companion decompression subroutines in the z80 library.
- [appmake] +rom added to manipulate raw binaries; options include code injection, extraction and conversion to intel hex format.
