# Program:  NewNightlyTest.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. Submits this information 
#           to llvm.org where it is placed into the nightlytestresults database.
#
# Modified heavily by Patrick Jenkins, July 2006
#
# 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.
#  -noremoveresults Do not remove the WEBDIR after it has been built.
#  -nobuild         Do not build llvm. If tests are enabled perform them
#                   on the llvm build specified in the build directory
#  -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.
#  -nodejagnu       Do not run feature or regression tests
#  -parallel        Run two parallel jobs with GNU Make.
#  -release         Build an LLVM Release version
#  -enable-llcbeta  Enable testing of beta features in llc.
#  -disable-llc     Disable LLC tests in the nightly tester.
#  -disable-jit     Disable JIT tests in the nightly tester.
#  -disable-cbe     Disable C backend tests in the nightly tester.
#  -verbose         Turn on some debug output
#  -debug           Print information useful only to maintainers of this script.
#  -nice            Checkout/Configure/Build with "nice" to reduce impact
#                   on busy servers.
#  -f2c             Next argument specifies path to F2C utility
#  -nickname        The next argument specifieds the nickname this script
#                   will submit to the nightlytest results repository.
#  -gccpath         Path to gcc/g++ used to build LLVM
#  -cvstag          Check out a specific CVS tag to build LLVM (useful for
#                   testing release branches)
#  -target          Specify the target triplet
#  -cflags          Next argument specifies that C compilation options that
#                   override the default.
#  -cxxflags        Next argument specifies that C++ compilation options that
#                   override the default.
#  -ldflags         Next argument specifies that linker options that override
#                   the default.
#  -compileflags    Next argument specifies extra options passed to make when
#                   building LLVM.
#  -use-gmake       Use gmake instead of the default make command to build
#                   llvm and run tests.
#
#  ---------------- Options to configure llvm-test ----------------------------
#  -extraflags      Next argument specifies extra options that are passed to
#                   compile the tests.
#  -noexternals     Do not run the external tests (for cases where povray
#                   or SPEC are not installed)
#  -with-externals  Specify a directory where the external tests are located.
#  -submit-server   Specifies a server to submit the test results too. If this
#                   option is not specified it defaults to 
#                   llvm.org. This is basically just the address of the 
#                   webserver
#  -submit-script   Specifies which script to call on the submit server. If
#                   this option is not specified it defaults to
#                   /nightlytest/NightlyTestAccept.cgi. This is basically 
#                   everything after the www.yourserver.org.
#
# 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 will be created if it does not exist.
# LLVMGCCDIR is the directory in which the LLVM GCC Front End is installed
#  to. This is the same as you would have for a normal LLVM build.
