   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 #  -nofeaturetests  Do not run the feature tests.
  17 #  -noregressiontests Do not run the regression tests.
  18 #  -notest          Do not even attempt to run the test programs. Implies
  19 #                   -norunningtests.
  20 #  -norunningtests  Do not run the Olden benchmark suite with
  21 #                   LARGE_PROBLEM_SIZE enabled.
  22 #  -parallel        Run two parallel jobs with GNU Make.
  23 #  -release         Build an LLVM Release version
  24 #  -pedantic        Enable additional GCC warnings to detect possible errors.
  25 #  -enable-linscan  Enable linearscan tests
  26 #  -disable-codegen Disable LLC and JIT tests in the nightly tester.
  27 #  -verbose         Turn on some debug output
  28 #  -debug           Print information useful only to maintainers of this script.
  29 #
  30 # CVSROOT is the CVS repository from which the tree will be checked out,
  31 #  specified either in the full :method:user@host:/dir syntax, or
  32 #  just /dir if using a local repo.
  33 # BUILDDIR is the directory where sources for this test run will be checked out
  34 #  AND objects for this test run will be built. This directory MUST NOT
  35 #  exist before the script is run; it will be created by the cvs checkout
  36 #  process and erased (unless -noremove is specified; see above.)
  37 # WEBDIR is the directory into which the test results web page will be written,
  38 #  AND in which the "index.html" is assumed to be a symlink to the most recent
  39 #  copy of the results. This directory MUST exist before the script is run.
