  25 The <I>special</I><B>_</B><I>decalpha</I> program does special processing to
  26 interface with the DEC ALPHA back-end compiler. It does
  27 this by means of ``#pragma'' lines, both ``#pragma'' lines
  28 in the input from system header files that give SUIF
  29 information about the back-end, and ``#pragma'' lines that
  30 SUIF puts in the output C files to communicate information
  31 SUIF has to the back-end compiler. It also does special
  32 optimizations that are specific to the DEC ALPHA back-end.
  33 <P>
  34 This program should be run twice, once after the front end
  35 with the ``-in'' option to read in annotations, and once
  36 just before s2c with the ``-out'' option. The
  37 ``-prefetches-to-dec''    and     ``-kill-dec-prefetches''
  38 options are only used if prefetching instructions need to
  39 be passed to the DEC Fortran compiler. If that is the
  40 case, this program should be run two more times, once with
  41 ``-prefetches-to-dec'' before the Fortranizer, then once
  42 with ``-kill-dec-prefetches'' after the Fortranizer before
  43 the remaining code is translated to C.
