 Most benchmarks are built using one or more types of 
 profile-driven feedback.  The types used are designated
 by abbreviations in the notes:

 +CFB: Code generation is optimized by the compiler, using 
       feedback from a training run.  These commands are
       done before the first compile (in phase "fdo_pre0"):

            mkdir /tmp/pp
            rm -f /tmp/pp/${baseexe}*

       and these flags are added to the first and second compiles:

            PASS1_CFLAGS = -prof_gen_noopt -prof_dir /tmp/pp
            PASS2_CFLAGS = -prof_use       -prof_dir /tmp/pp
 
      (Peak builds use /tmp/pp above; base builds use /tmp/pb.)

 +IFB: Icache usage is improved by the post-link-time optimizer 
       Spike, using feedback from a training run.  These commands
       are used (in phase "fdo_postN"):  

            mv ${baseexe} oldexe
            spike oldexe -feedback oldexe -o ${baseexe}

 +PFB: Prefetches are improved by the post-link-time optimizer 
       Spike, using feedback from a training run.  These
       commands are used (in phase "fdo_post_makeN"):

            rm -f *Counts*
            mv ${baseexe} oldexe
            pixie -stats dstride oldexe 1>pixie.out 2>pixie.err
            mv oldexe.pixie ${baseexe}

       A training run is carried out (in phase "fdo_runN"), and 
       then this command (in phase "fdo_postN"):

            spike oldexe -fb oldexe -stride_prefetch -o ${baseexe}

 When Spike is used for both Icache and Prefetch improvements, 
 only one spike command is actually issued, with the Icache 
 options followed by the Prefetch options.

 Spike, and the Program Analysis Tools, are part of the Developers' 
 Tool Kit Supplement, http://www.tru64unix.compaq.com/dtk/ .  The
 features used in this SPEC submission will be available at the web 
 site as a beta kit in August, 2001, and as a production release in
 October, 2001.  The C compiler for this SPEC submission has been
 available at the same location, as a production release, since
 May, 2001.
