download. z88 Development Kit C Cross Compiler for the z80 with assembly ...
It's been a year since the last release so it was time for another. This is
another transitional release on the way to version 2.0 and hopefully we'll get
there for the next one.
Some notes:
==========================
Z88DK - v1.99B 10 Jan 2017
==========================
Z88dk is a development kit for z80 computers that contains the tools and
assembly language libraries necessary to develop code in either C or assembly
language for z80-based machines.
Over 50 different z80 machines have CRTs in the toolkit, allowing C programs to
be compiled for them out-of-the-box.
There are two C compilers supported (sccz80 and sdcc), two independent C
libraries included (the classic and new), an assembler/linker/librarian
(z80asm), and a data compression tool (zx7).
This is the second transition release in anticipation of v2.0.

--8<-- list of changes below
=======
PACKAGE
=======
* The win32 and osx packages are complete and now include the zsdcc & zsdcpp
binaries. zsdcc is z88dk's customization of the sdcc compiler. Other users can
compile zsdcc from source.
* A VS2015 solution file is now available in z88dk/win32 for building all z88dk
binaries except zsdcc & zsdcpp. Instructions for building zsdcc & zsdcpp can be
found in the install instructions link above.
========================
ZCC - Compiler Front End
========================
* M4 has been added as an optional macro pre-processor. Any filename ending
with extension ".m4" will automatically be passed through M4 and its output
written to the original source directory with the ".m4" extension stripped
prior to further processing. The intention is to allow source files like
"foo.c.m4", "foo.asm.m4", "foo.h.m4" and so on to be processed by M4 and then
that result to be processed further according to the remaining file extension.
* In conjunction with the above, a collection of useful M4 macros has been
started in "z88dk.m4" that can be included in any ".m4" file processed by zcc.
Currently macros implementing for-loops and foreach-loops are defined.
* List files ending with extension ".lst" can be used to specify a list of
source files for the current compile, one filename per line. The list file is
specified on the compile line with prefix @ as in "@foo.lst". List files can
contain any source files of any type understood by zcc and individual lines can
be commented out with a leading semicolon. Paths of files listed in list files
can be made relative to the list file itself (default) or relative to the
directory where zcc was invoked (--listcwd). List files can list other list
files, identified with leading '@'.
* zcc now processes all files it is given to the final output file type
specified. For example, with "-E" specified, all listed .c files will be run
through the C pre-processor individually and all output copied to the output
directory. Previous to this, only the first file listed was processed unless a
binary was being built.
* -v gives more information on what steps zcc takes to process each source file.
* -x now builds a library out of the source files listed.
* -c by itself will generate individual object files for each input source
file. However, if -c is coupled with an output filename as in "-o name", a
single consolidated object file will now be built instead of individual ones.
The intention is to provide a means to generate identical code in separate
compiles by allowing this single object file to be specified on different
compile lines.
* Better error reporting for source files with unrecognized types.
* Better parsing for compile line pragmas; pragma integer parameters can now be
in decimal, hexadecimal or octal.
* -pragma-include added to allow a list of compile time pragmas to be read from
a file as in "-pragma-include:zpragma.inc". This way projects can consolidate
pragmas in one location; this is especially important for the new c library
which uses pragmas extensively to customize the crt.
* -pragma-export added, is similar to -pragma-define but the assembly label
defined as a constant on the compile line is made public so that its value is
visible across all source files.
* --list will generate ".lis" files for each source file in a compile to a
binary. The ".lis" file is an assembly listing of source prior to input to the
linker.
* --c-code-in-asm causes C code to be interspersed as comments in any generated
assembly listing associated with C source files.
* ".s" files are now understood by zcc to be asz80-syntax assembly language
source files. This allows sdcc project files written in assembly language to be
assembled by z88dk. asz80 mnemonics are non-standard so zcc attempts to
translate to standard zilog mnemonics before assembling. You can see the
translation to standard zilog form by using "-a" on a compile line. This is
still a work-in-progress feature.
* --no-crt allows compiles to proceed without using the library's supplied crt
for a target. The first file listed on a compile line will stand in as the crt
and will be responsible for initialization and setting up the memory map.
* Temporary files are always created in the temp directory. The option
"-notemp" has been removed.
* Library and include search paths have been fixed to honour the order
specified on the compile line. This allows the user to override library
functions when desired.
* Source files are now processed from their original location so that includes
can be properly resolved. Previously this was only done for .c files but this
now applies to other file types.
* clang/llvm compilation is in an experimental state.
Known issues:
* Spaces in paths or filenames can be a problem.
* When --c-code-in-asm is active, unicode characters from .c source files
appearing as comments in translated asm may cause the tools to crash.
==========================
SCCZ80 - Native C Compiler
==========================
* Correct floating point constant handling.
* New __SAVEFRAME__ function decorator to allow saving of ix during a function
call.
* -standard-escape-chars to make \n and \r output standard character codes
========================================
ZSDCC - Customization of SDCC C Compiler
========================================
* Updated to SDCC 3.6.5 #9824.
* SDCC's native C pre-processor is now used so that line numbers corresponding
to reported errors are accurate.
* Peephole-z80 fixed to accurately report registers affected by instructions,
allowing accurate application of peephole rules.
* inSequence('stride' %1 %2 %3 ...) added as peephole rule qualifier to allow
testing whether consecutive bytes in memory are being accessed.
* Peephole-z80 made aware of z88dk special functions which represent code
inlined by the library.
* Approximately 300 new peephole rules added to the aggressive peephole set
(-SO3).
* Peephole rules added to fix some known code generation bugs and to fix SDCC's
critical sections for nmos processors.
* --opt-code-size now significantly reduces code size for programs using 32-bit
longs, 64-bit longlongs and floats.
* chars have been made unsigned by default. Use --fsigned-char to change to
signed.
* For loops can now declare variables in the initializer statement.
* An rodata section has been properly implemented so that all constant data
generated by sdcc is assigned there.
=====================================
Z80ASM - Assembler, Linker, Librarian
=====================================
* Handle input files more predictably: link .o files; assemble any other
extension; append a .asm or .o option to the file name to allow just the
basename.
* Make a consolidated object file with -o and not -b: all the object modules
are merged, the module local symbols are renamed <module>_<symbol>
* Link the library modules in the command line sequence (it was depth-first).
* Add directory of assembled file to the end the include path to allow includes
relative to source location.
* Remove all generated files at start of assembly to remove files from previous
runs.
* Remove deprecated directives: XREF and LIB (replaced by EXTERN), XDEF and
XLIB (replaced by PUBLIC), OZ (keep CALL_OZ).
* Rename DEFL to DEFQ to reserve DEFL for macro variables; rename DS.L by DS.Q
* Constants for section sizes: prune empty sections, rename ASMHEAD, ASMTAIL
and ASMSIZE to __head, __tail and __size respectively, rename
ASM<HEAD|TAIL|SIZE>_<section_name> to __<section_name>_<head|tail|size>
* Environment variables no longer used: Z80_OZFILES, Z80_STDLIB
* Command line option -r, --origin: accept origin in decimal or hexadecimal
with '0x' or '$' prefix
* Command line options: -i, -x: require a library name
* Command line options: remove -RCMX000, keep only --RCMX000
* Command line options: remove -plus, keep only --ti83plus
* Command line options: remove -IXIY and --swap-ix-iy, keep --IXIY
* Command line options: remove --sdcc, -nm, --no-map, -ng, --no-globaldef, -ns,
--no-symtable, -nv, --no-verbose, -nl, --no-list, -nb, --no-make-bin, -nd,
--no-date-stamp, -a, --make-updated-bin, -e, --asm-ext, -M, --obj-ext, -t
* Make symbol files, map files and reloc files optional; do not merge symbols
in the list file; do not paginate and cross-reference symbols in list file;
rename list file to file.lis (@file.lst is used as project list)
* Unify format used in map files, symbol files and global define files, output
list of symbols only once.
* Include symbols computed at link time in the global define file.
* Simplify output of --verbose
===========================================================
APPMAKE - Processes Output Binaries to Target Suitable Form
===========================================================
* +rom can now generate binaries for ROM chips mapped into a specific address
range.
* +sms now generates bankswitched .sms files as output.
* +zx now has option to generate headerless .tap files.
* Appmake now understands three compile models -- ram (destined for ram, no
stored data section), rom (destined for rom, stored data section is a copy) and
compressed rom (destined from rom, stored data section is compressed) -- and
will form output files accordingly.
=================
CLASSIC C LIBRARY
=================
* SDCC can now be used to compile using the classic library.
* Rewritten and modular printf core, added (v)snprintf.
* Rewritten and modular scanf core.
* Ports are now section aware.
* Support for compressed data section model.
* Support for copied data section model.
* User overridable fputc_cons.
* New target: Microbee. Support for various GFX modes and 1 bit sound.
* New target: Robotron kc. Support for various GFX modes and 1 bit sound.
* New target: z1013. Support for various GFX modes and 1 bit sound.
* New target: z9001. Support for various GFX modes and 1 bit sound.
* CP/M Plus on Spectrum.
* CP/M extenstions forced to upper case.
* CP/M extensions improved on Aussie Byte, trs-80 and Epson PX.
* GFX Library: improved the vector rendering functions, now bigger pictures can
be drawn and higher resolutions are supported. Various fixes.
* Custom text configuration (font, resolution) can be done at compile time for
targets with ansi VT support on graphics display.
=============
NEW C LIBRARY
=============
* 64-bit integers are now fully supported in the library.
* The fprintf/fscanf cores can now have conversion specifiers individually
enabled or disabled at compile time. This allows the printf/scanf cores to be
tailored to the minimum size required.
* fprintf %aefg precision formatting corrected.
* Intrinsics have been introduced as a method to inline assembly code without
disturbing optimization. This provides a means to insert assembly labels (whose
addresses will appear in map files), simple assembly instructions such as "di"
and "ei", and atomic loads/stores into C code without affecting the compiler's
optimizer. See https://www.z88dk.org/wiki/doku.php?id=libnew:intrinsic
* The library has had a preserves_registers attribute attached to every
function that informs sdcc which registers will not be affected by a library
call and allows sdcc to generate better code around library calls.
* aplib added as another data decompression utility.
* setjmp/longjmp state increased to include the value of IY for sdcc compiles.
This was necessary as sdcc sometimes requires the value of IY to be preserved
at points in the program.
* New target: rc2014 (preliminary). This target is still being developed by
rc2014 users.
* New target: Sega Master System. The target is able to automatically create
bankswitched rom cartridges with signatures.
* ZX Spectrum target: interfaces to the bifrost and nirvana multicolour sprite
engines added.
* The CRT startup code has been made more flexible, allowing a wide range of
features to be selected via pragmas at compile time. See
