[comp.unix.wizards] Sun 3/50 MMU

mjc@brueer.UUCP (03/26/87)

This little program produces a segmentation fault on a Sun 3/75 or 3/110
but runs to the end on a 3/50. It would appear that the Sun 3/50 MMU is
similar to the Sun 2 MMU in that it only looks at the bottom 24 bits
of the address.

Is this the true story, and if so is there a 
compiler #define that can be used to discriminate between
a Sun 3/50 and a 3/75 in the same way that #ifdef mc68020 is
used to tell the difference between a Sun 3 and Sun 2.

main()
{
  char *p = "Hello world" ;

  p += 0xc0000000 ;

  printf ("%s\n",p ) ;
}
