   3 # Program:  NightlyTest.pl
   4 #
   5 # Synopsis: Perform a series of tests which are designed to be run nightly.
   6 #           This is used to keep track of the status of the LLVM tree, tracking
   7 #           regressions and performance changes.  This generates one web page a
   8 #           day which can be used to access this information.
   9 #
  10 # Syntax:   NightlyTest.pl [OPTIONS] [CVSROOT BUILDDIR WEBDIR]
  11 #   where
  12 # OPTIONS may include one or more of the following:
  13 #  -nocheckout      Do not create, checkout, update, or configure
  14 #                   the source tree.
  15 #  -noremove        Do not remove the BUILDDIR after it has been built.
  16 #  -notest          Do not even attempt to run the test programs. Implies
  17 #                   -norunningtests.
  18 #  -norunningtests  Do not run the Olden benchmark suite with
  19 #                   LARGE_PROBLEM_SIZE enabled.
  20 #  -noexternals     Do not run the external tests (for cases where povray
  21 #                   or SPEC are not installed)
  22 #  -nodejagnu       Do not run feature or regression tests
  23 #  -parallel        Run two parallel jobs with GNU Make.
  24 #  -release         Build an LLVM Release version
  25 #  -enable-llcbeta  Enable testing of beta features in llc.
  26 #  -disable-llc     Disable LLC tests in the nightly tester.
  27 #  -disable-jit     Disable JIT tests in the nightly tester.
  28 #  -verbose         Turn on some debug output
  29 #  -debug           Print information useful only to maintainers of this script.
  30 #  -nice            Checkout/Configure/Build with "nice" to reduce impact
  31 #                   on busy servers.
  32 #  -f2c             Next argument specifies path to F2C utility
  33 #  -gnuplotscript   Next argument specifies gnuplot script to use
  34 #  -templatefile    Next argument specifies template file to use
  35 #  -gccpath         Path to gcc/g++ used to build LLVM
  36 #  -cvstag          Check out a specific CVS tag to build LLVM (useful for
  37 #                   testing release branches)
  38 #  -target          Specify the target triplet
  39 #  -cflags          Next argument specifies that C compilation options that
  40 #                   override the default.
  41 #  -cxxflags        Next argument specifies that C++ compilation options that
  42 #                   override the default.
  43 #  -ldflags         Next argument specifies that linker options that override
  44 #                   the default.
  45 #
  46 #  ---------------- Options to configure llvm-test ----------------------------
  47 #  -spec2000path    Path to the benchspec directory in the SPEC 2000 distro
  48 #  -spec95path      Path to the benchspec directory in the SPEC 95 distro.
  49 #  -povraypath      Path to the povray sources
  50 #  -namdpath        Path to the namd sources
  51 #
  52 # CVSROOT is the CVS repository from which the tree will be checked out,
  53 #  specified either in the full :method:user@host:/dir syntax, or
  54 #  just /dir if using a local repo.
  55 # BUILDDIR is the directory where sources for this test run will be checked out
  56 #  AND objects for this test run will be built. This directory MUST NOT
  57 #  exist before the script is run; it will be created by the cvs checkout
  58 #  process and erased (unless -noremove is specified; see above.)
  59 # WEBDIR is the directory into which the test results web page will be written,
  60 #  AND in which the "index.html" is assumed to be a symlink to the most recent
  61 #  copy of the results. This directory will be created if it does not exist.
  62 # LLVMGCCDIR is the directory in which the LLVM GCC Front End is installed
  63 #  to. This is the same as you would have for a normal LLVM build.
