    424424The RTEMS Project currently does not have a MacOS X computer and would
    425425have to have one before these could be supported long term.

    428 
    429 '''Status:''' [wiki:LaurentGuerby LaurentGuerby] has implemented the multilib'ing of the Ada run-time libraries. 
    430  *  gnatmake does not yet properly process -mcpu options like gcc so you have to use special command line options that make you way too aware of the multilib.
    431 
    432 {{{
    433 You have to use --RTS together with -m for gnatmake
    434 to work for non-default multilib:
    435 
    436 gnatmake $FLAGS --RTS=$(gcc -print-multi-directory $FLAGS)
    437 }}}
    438 
    439  *  There may as yet be target specific issues to work around where the same source file does not support all variants.
    440 
    441 The goal of this project is to implement Multilib support for GNU Ada (GNAT) run-time libraries in GCC.  This primary
    442 focus of this project will be to augment the existing configure and Makefile infrastructure for the GNU Ada run-time
    443 libraries in GCC to build multilib rather than a single library variant.
    444 
    445 Multilib is a GNU term for building a single source library to be tailored for multiple CPU variants within a single architecture.
    446 This is done because even within a CPU architecture, not every CPU model is object code compatible.  For example, on the RTEMS
    447 SPARC tools, we provide four libc.a versions -- SPARC V7 and V8 with and without hardware floating point support.  Similarly,
    448 the m68k target supports many m680x0 and Coldfire core implementations with and without hardware floating point.
