SDCC 3.3.0 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 visible or interesting for the SDCC users is implemented, it should be added to the following list.

  • 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.
  • Suport for C11 _Alignof operator.
