 The SPARC target in GDB was recently greatly improved.  This should
 now work if:
 
 1. You compile itself GDB as a 64-bit binary.  To do this configure
    with either:
 
    CC="cc -xarch=v9" ./configure
 
    if you're using the native, unbundled Sun compiler, or
 
    CC="gcc -m64" ./configure
 
    if you're using GCC that's capable of generating 64-bit binaries.
 
 2. You compile your 64-bit programs using GCC.  GDB can't handle the
    64-bit stabs debugging information, and that's what the Sun
    compilers produce.  If you've got a recent Sun compiler, you might
    want to try -xdebugformat=dwarf, but as they say YMMV.
