SDCC 3.2.0 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.

  • 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</tt>; PIC14 <tt>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).
