OK to commit? Of the targets listed there as still using fixproto, hppa[12]*-*-hpux10* has had its fixproto use removed so it is not on the deprecation list. I encourage anyone using GCC for IRIX, 2BSD or AIX 4.1 and 4.2 to stop those targets from using fixproto (possibly just removing the use_fixproto setting, possibly adding new fixes to fixincludes to replace any important changes fixproto made) and to remove the deprecations at the same time. (Please also send your test results to gcc-testresults if you are using one of those targets.) Deprecation of targets not converted to IRA will wait until after IRA is on trunk and the old allocator is removed. 2008-07-03 Joseph Myers * config.gcc (arm-*-coff*, armel-*-coff*, h8300-*-*, i[34567]86-*-aout*, i[34567]86-*-coff*, m68k-*-aout*, m68k-*-coff*, sh-*-*, mips-sgi-irix[56]*, pdp11-*-bsd, rs6000-ibm-aix4.[12]*, powerpc-ibm-aix4.[12]*): Deprecate targets, excluding more specific h8300-*-* and sh-*-* targets.

  • Support for a number of older systems and recently + unmaintained or untested target ports of GCC has been declared + obsolete in GCC 4.4. Unless there is activity to revive them, the + next release of GCC will have their sources permanently + removed.

    + +

    The following ports for individual systems on particular + architectures have been obsoleted:

    + +
      +
    • Generic a.out on IA32 and m68k (i[34567]86-*-aout*, + m68k-*-aout*)
      • +
    • Generic COFF on ARM, H8300, IA32, m68k and SH (arm-*-coff*, + armel-*-coff*, h8300-*-*, i[34567]86-*-coff*, m68k-*-coff*, + sh-*-*). This does not affect other more specific targets + using the COFF object format on those architectures, or the + more specific H8300 and SH targets (h8300-*-rtems*, + h8300-*-elf*, sh-*-elf*, sh-*-symbianelf*, sh-*-linux*, + sh-*-netbsdelf*, sh-*-rtems*, sh-wrs-vxworks).
      • +
    • IRIX on MIPS (mips-sgi-irix[56]*)
      • +
    • 2BSD on PDP-11 (pdp11-*-bsd)
      • +
    • AIX 4.1 and 4.2 on PowerPC (rs6000-ibm-aix4.[12]*, + powerpc-ibm-aix4.[12]*)
      • +
    + +
    • + +
  • The protoize and unprotoize + utilities have been obsoleted and will be removed in GCC 4.5. + These utilities have not been installed by default since GCC + 3.0.
