Solaris 2

+
    +

    New Features

    +
  • Support symbol versioning with the Sun linker.
    • +
  • Enable full ISO C99 support for C++ on Solaris 10+.
    • +
  • Support thread-local storage (TLS) with the Sun assembler on + Solaris 2/x86.
    • +
  • Support TLS on Solaris 8/9 if prerequisites are met.
    • +
  • Support COMDAT group with the GNU assembler and recent Sun + linker.
    • +
  • Support the Sun assembler visibility syntax.
    • +
  • Default Solaris 2/x86 to -march=pentium4 (Solaris + 10+) resp. -march=pentiumpro (Solaris 8/9).
    • +
  • Don't use SSE on Solaris 8/9 x86 by default.
    • +
  • Enable 128-bit long double (__float128) support on + Solaris 2/x86.
    • +

    ABI Change

    +
  • Change the ABI for returning 8-byte vectors like + __m64 in MMX registers on Solaris 10+/x86 to match the + Sun Studio 12.1+ compilers. This is an incompatible change. + If you use such types, you must either recompile all your code with + the new compiler or use the new -mvect8-ret-in-mem + option to remain compatible with previous versions of GCC and + Sun Studio.

Windows x86/x86_64

  • Initial support for decimal floating point.
