# Program: NightlyTest.pl
#
# Synopsis: Perform a series of tests which are designed to be run nightly.
# This is used to keep track of the status of the LLVM tree, tracking
# regressions and performance changes. This generates one web page a
# day which can be used to access this information.
#
# Syntax: NightlyTest.pl [OPTIONS] [CVSROOT BUILDDIR WEBDIR]
# where
# OPTIONS may include one or more of the following:
# -nocheckout Do not create, checkout, update, or configure
# the source tree.
# -noremove Do not remove the BUILDDIR after it has been built.
# -notest Do not even attempt to run the test programs. Implies
# -norunningtests.
# -norunningtests Do not run the Olden benchmark suite with
# LARGE_PROBLEM_SIZE enabled.
# -parallel Run two parallel jobs with GNU Make.
# -enable-linscan Enable linearscan tests
#
# CVSROOT is the CVS repository from which the tree will be checked out,
# specified either in the full :method:user@host:/dir syntax, or
# just /dir if using a local repo.
# BUILDDIR is the directory where sources for this test run will be checked out
# AND objects for this test run will be built. This directory MUST NOT
# exist before the script is run; it will be created by the cvs checkout
# process and erased (unless -noremove is specified; see above.)
# WEBDIR is the directory into which the test results web page will be written,
# AND in which the "index.html" is assumed to be a symlink to the most recent
# copy of the results. This directory MUST exist before the script is run.
