z88dk 1.99A 23.Dec.2015
Major changes incorporated into z88dk. This is a transition release in anticipation of v2.0.
Two C compilers are supported (sccz80 - z88dk's native C compiler - and sdcc).
Two different C libraries are present (classic - the same library as pre 1.99A - and new).
Accordingly, there are now three different compile modes:
1. Compile with sccz80 and the classic C library. This is equivalent to pre-1.99A.
2. Compile with sccz80 and the new C library. Compile lines include "-clib=new".
3. Compile with sdcc and the new C library. Compile lines include "-clib=sdcc_ix" or "-clib=sdcc_iy".
[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.
The new C library completes C standards compliance for sdcc and allows sdcc produced binaries to be smaller and faster.
