A new version of the SDCC C compiler is available. You can use SDCC to develop for the Amstrad CPC, e.g. with using the SDCC Code::Blocks template or the programming tutorials by Mochilote. The new version contains also some optimisations for the Z80 port, so be sure to update it. You can download it from http://sdcc.sourceforge.net.

Changes:

  • New TLCS90 (Toshiba Z80 clone) target support
  • New STMicroelectronics STM8 target support
  • Support for named address spaces in ROM
  • Detects supported devices by gputils when building SDCC
  • Numerous feature requests and bug fixes are included as well.

A new version of the SDCC C compiler is available. You can use SDCC to develop for the Amstrad CPC, e.g. with using the SDCC Code::Blocks template or the programming tutorials by Mochilote. The new version contains a lot of optimisations for the Z80 backend again, so be sure to update. You can download it from http://sdcc.sourceforge.net.

Changes:

  • Many small improvements in code generation for the z80-related ports – merged smallopts branch
  • lospre (currently enabled for z80-related and hc08-related ports only) – merged lospre branch
  • More efficient initialization of globals in z80, z180, r2k and r3ka ports.
  • Inclusion of tests from the gcc test suite into the sdcc regression test suite led to many bugs being found and fixed.
  • Split sdas390 from sdas8051
  • Merged big parts of ASxxxx v5 into sdas
  • New pic devices (synchronization with MPLABX 1.60). (Except for very old MCU-s.)
  • New script which disassembles those hex files, in which MCS51 code there is. (mcs51-disasm.pl)
  • Added the PIC16F1788 and PIC16F1789 devices.
  • C11 _Alignof operator.
  • C11 _Alignas alignment specifier.
  • C11 _Static_Assert static assertion.

Numerous feature requests and bug fixes are included as well.

Artaburu released a first beta version of his utility library for the SDCC C compiler. E.g. Mariano the dragon or the recently released Nanako Descend To Hell was written with this library (using the Z88dk compiler as backend) and so it contains a lot of graphics functions, keyboard functions, map functions, etc. You can download it from the Google Code page of the CPCRSlib.

Here are the changes since my last posting:

10/24/2012

cpcrslib for SDCC (beta) released.

05/21/2012

cpcwyzlib for SDCC released.

A new version of the SDCC C compiler is available. You can use SDCC to develop for the Amstrad CPC, e.g. with using the SDCC Code::Blocks template or the programming tutorials by Mochilote. In the new version, there are a lot of optimisations for the Z80 backend, so be sure to update if you already use the old version. You can download it from http://sdcc.sourceforge.net.

Changes:

  • Named address spaces with optimal placement of bank selection calls.
  • _Noreturn.
  • –std-c11 command line option for ISO C11.
  • ucsim support for the LR35902 (gameboy CPU).
  • The gbz80 port is alive again, there were many bug fixes and the generated code is much better now.
  • Pic 14 enhanced core libraries are included in sdcc builds by default
  • Added pic 14 enhanced core devices: 16f1503, 16f1508, 16f1509, 16f1516, 16f1517, 16f1518, 16f1519, 16f1526, 16f1527, 16f1946, 16f1947
  • PIC14/PIC16: Implemented __critical; PIC14 __critical function cannot have arguments for now, though
  • inclusion of some tests from the gcc test suite into the sdcc regression test suite led to many bugs being found and fixed.
  • Many macros with previously non-standard-compliant names have been renamed (SDCC_REVISION to __SDCC_REVISION, etc).
  • setjmp() / longjmp() for the z180 and r2k ports.
  • Added sdar archive managing utility. sdar and sdranlib are derived from GNU binutils package
  • Added support for pic 14 core devices: 16f720, 16f721, 16f882, 16f883, 16f884, 16f747, 16f946
  • sdcpp synchronized with GNU cpp 4.6.3
  • Added support for pic 18f1230/18f1330 device family
  • Implemented #pragma config for pic16 target
  • sdcc now works on Debian GNU/Hurd.
  • New register allocator for the hc08 port, resulting in better code being generated.
  • New s08 port.
  • New r3ka port.
  • Many small improvements in the z80, hc08 and r2k code generation, reducing code size.
  • Shift, multiplication, division and returning of long long are now supported (modulo for long long is still missing, integer literals of type long long are broken).

A new version of the SDCC C compiler is available. You can use SDCC to develop for the Amstrad CPC, e.g. with using the SDCC Code::Blocks template or the article in the CPCWiki. In the new version, there are a lot of optimisations for the Z80 backend, so be sure to update if you already use the old version. You can download it from http://sdcc.sourceforge.net.

Changes:

  • include/pic, non-free/include/pic, lib/pic, non-free/lib/pic renamed to */pic14
  • implemented –fomit-frame-pointer for mcs51
  • support for use of sdcc in z88dk (–reserve-regs-iy and –no-optsdcc-in-asm options; smallc calling convention)
  • new register allocator in the z80 and gbz80 ports (optimal when using –opt-code-size and a sufficiently high value for –max-allocs-per-node for the z80 port)
    C99 designated initializers
  • added strxfrm() and strcoll() functions; strerror() is the only string handling function still missing
  • added support for pic18f2xk22/pic18f4xk22 family (requires gputils > 0.14.0 and –enable-new-pics configure flag)
  • added support for enhanced core pic14 devices (requires gputils > 0.14.0 and –enable-new-pics configure flag)
  • setjmp() / longjmp() for the z80 port
  • _Bool / bool for the hc08, pic16 and pic14 ports
  • sdcpp synchronized with GNU cpp 4.6.1
  • z180 port
  • very basic (no integer constants, multiplication, division, shifts or use as return value) support for data types long long, unsigned long long, int_fast64_t, int_least64_t, int64_t, uint_fast64_t, uint_least64_t, uint64_t in the z80, z180, r2k and gbz80 ports
  • r2k port for the Rabbit 2000 and Rabbit 3000
  • Numerous feature requests and bug fixes are included as well.
