SDCC 2.8.0 Feature List

There is always a problem to create a list of new features when a new SDCC release is announced. The following list is an attempt to create such a list "on the fly". Every time a new feature which is interesting for the SDCC users is implemented, it should be added to the following list.

  • added predefined preprocessor macro SDCC_REVISION holding SDCC's subversion revision number
  • added preprocessor macros SDCC_PARMS_IN_BANK1, SDCC_FLOAT_REENT and SDCC_INT_LONG_REENT
  • sdcpp synchronized with GNU cpp 4.2.3
  • multiple infiles for sdcclib
  • added option --acall-ajmp: replaces lcall/ljmp with acall/ajmp.
  • added support for many PIC devices
  • sdcc executables on Mac OS X are built as universal binaries, so that they can run on both ppc and i386 Mac OS X
  • added --Werror command line option
  • Windows installer enhancements
  • generation of cdb debug info for as-z80 and link-z80
  • generation of cdb debug info for variables in pdata for mcs51
  • Tail call optimization for functions that take no parameters on Z80
  • Improved multiplication of unsigned chars on Z80
  • ISO/IEC 9899 standard compliant integer promotion of integer function arguments if --std-cXX is defined in command line
