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.
