NAME
er_archive - construct function and module lists for a per-
formance experiment
SYNOPSIS
er_archive [ -qFA ] experiment.
er_archive -V
DESCRIPTION
er_archive runs automatically when an experiment completes
normally, or upon initial invocation of the analyzer or
er_print command on an experiment. It reads the list of
shared objects referenced in the experiment, and constructs
an archive file for each. Each output file is named with a
suffix of .archive, and contains function and module map-
pings for the shared object. If the target program ter-
minates abnormally, er_archive might not run.
If the user wishes to examine the experiment on a different
machine from the one on which it was recorded, er_archive
must be manually run on the experiment on the machine on
which the data was recorded.
A .archive file is generated for all shared objects refer-
enced in the experiment. If the shared object cannot be
found, or if it has a timestamp differing from that recorded
in the experiment, or if er_archive is run on a different
machine from that on which the experiment was recorded, the
.archive contains a warning. Warnings are also written to
stderr whenever er_archive is run manually (without the -q
flag).
OPTIONS
-q Do not write any warnings to stderr. Warnings are
incorporated into the .archive file, and shown in
the analyzer or er_print output.
-F Force writing or rewriting of .archive files.
This argument can be used to run er_archive by
hand, to rewrite files that had warnings.
-A Request writing of all load objects to experiment.
This argument can be used to generate experiments
that are more readily copied to a machine other
than the one on which the experiment was recorded.
-V Write version number information for er_archive
and exit.
COMPATIBILITY
er_archive does not work on experiments recorded with ear-
lier versions of the tools. If invoked on such experiments,
a warning is printed. Use the version of er_archive from
the release with which the experiment was recorded.
