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.
