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 or with the CPCtelera framework that is used e.g. in the CPCRetroDev development competition. The new version contains also some features for the Z80 port, so be sure to update it. You can download it from http://sdcc.sourceforge.net.

Changelog:

  • Support for struct / union assignment.
  • Optimizations in the stm8 backend relevant to soft float increase Whetstone score by two thirds.
  • Improvements in rematerialization in the stm8 backend improve code generation for struct, union and arrays.
  • New stack allocator reduces stack space usage for the stm8, z80, z180, gbz80, r2k, r3ka, tlcs90 backends.
  • New ez80_z80 backend for eZ80 in Z80 mode.
  • Removed deprecated sdcclib utility.
  • New pdk14 backend for Padauk µC with 14-bit wide program memory.
  • New in-development pdk15 backend for Padauk µC with 15-bit wide program memory.
  • Numerous other new features and bug fixes are included as well.

Changes:

  • Merged upstream binutils 2.25
  • New memory management with lower overhead
  • Changed default language dialect to –std-sdcc11
  • Diagnostic for missing type specifier: No implicit int outside of C90 mode anymore
  • C11 generic selections
  • char type is now unsigned by default (old behaviour can be restored using –fsigned-char)
  • Character constants are now of type int instead of char.
  • ISO C95 and ISO C11 wide character constants
  • ISO C95 and ISO C11 wide string literals
  • Basic standard library support for wide characters: c16rtomb(), mbrtoc16(), mbsinit(), mbtowc(), mbrlen(), mbrtoc32, c32rtomb(), mbrtowc(), wcrtomb(), mblen(), wctomb()
  • Treat all ports the same in the manual (i.e. mcs51-specific stuff is now clearly described as such)
  • Reorganized interrupt handling for z80, z180, r2k, r3ka, tlcs90, gbz80 backends
  • Workaround for stm8 division hardware bug
  • ELF/DWARF support for stm8
  • Output symbol table for ELF
  • pic16 port now uses standard-compliant crt0iz that initializes static and globals to 0 by default
  • Numerous feature requests and bug fixes

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.
