      8 # Program:  NewNightlyTest.pl
      9 #
     10 # Synopsis: Perform a series of tests which are designed to be run nightly.
     11 #           This is used to keep track of the status of the LLVM tree, tracking
     12 #           regressions and performance changes. Submits this information
     13 #           to llvm.org where it is placed into the nightlytestresults database.
     14 #
     15 # Syntax:   NightlyTest.pl [OPTIONS] [CVSROOT BUILDDIR WEBDIR]
     16 #   where
     17 # OPTIONS may include one or more of the following:
     18 #
     19 # MAIN OPTIONS:
     20 #  -config LLVMPATH If specified, use an existing LLVM build and only run and
     21 #                   report the test information. The LLVMCONFIG argument should
     22 #                   be the path to the llvm-config executable in the LLVM build.
     23 #                   This should be the first argument if given. NOT YET
     24 #                   IMPLEMENTED.
     25 #  -nickname NAME   The NAME argument specifieds the nickname this script
     26 #                   will submit to the nightlytest results repository.
     27 #  -nouname         Don't include uname data (machine will be identified by nickname only).
     28 #  -submit-server   Specifies a server to submit the test results too. If this
     29 #                   option is not specified it defaults to
     30 #                   llvm.org. This is basically just the address of the
     31 #                   webserver
     32 #  -submit-script   Specifies which script to call on the submit server. If
     33 #                   this option is not specified it defaults to
     34 #                   /nightlytest/NightlyTestAccept.php. This is basically
     35 #                   everything after the www.yourserver.org.
     36 #  -submit-aux      If specified, an auxiliary script to run in addition to the
     37 #                   normal submit script. The script will be passed the path to
     38 #                   the "sentdata.txt" file as its sole argument.
     39 #  -nosubmit        Do not report the test results back to a submit server.
     40 #
     41 #

     47 #  -noclean         Do not run 'make clean' before building.
     48 #  -nobuild         Do not build llvm. If tests are enabled perform them
     49 #                   on the llvm build specified in the build directory

     96 #
     97 # CVSROOT is ignored, it is passed for backwards compatibility.
     98 # BUILDDIR is the directory where sources for this test run will be checked out
     99 #  AND objects for this test run will be built. This directory MUST NOT
    100 #  exist before the script is run; it will be created by the svn checkout
    101 #  process and erased (unless -noremove is specified; see above.)
    102 # WEBDIR is the directory into which the test results web page will be written,
    103 #  AND in which the "index.html" is assumed to be a symlink to the most recent
    104 #  copy of the results. This directory will be created if it does not exist.
    105 # LLVMGCCDIR is the directory in which the LLVM GCC Front End is installed
    106 #  to. This is the same as you would have for a normal LLVM build.
