  11 # This script builds many different flavors of the LLVM ecosystem.  It
  12 # will build LLVM, Clang, llvm-gcc, and dragonegg as well as run tests
  13 # on them.  This script is convenient to use to check builds and tests
  14 # before committing changes to the upstream repository
  15 #
  16 # A typical source setup uses three trees and looks like this:
  17 #
  18 # official
  19 #   dragonegg
  20 #     trunk
  21 #   gcc
  22 #     trunk
  23 #   llvm
  24 #     trunk
  25 #       tools
  26 #         clang
  27 #     tags
  28 #       RELEASE_28
  29 #         tools
  30 #           clang
  31 #   llvm-gcc
  32 #     trunk
  33 #     tags
  34 #       RELEASE_28

  41 #     trunk
  42 #       tools

  44 #     tags
  45 #       RELEASE_28
  46 #         tools

  66 #     trunk
  67 #     tags
  68 #       RELEASE_28
  69 #
  70 # "gcc" above is the upstream FSF gcc and "gcc/trunk" refers to the
  71 # 4.5 branch as discussed in the dragonegg build guide.
  72 #
  73 # In a typical workflow, the "official" tree always contains unchanged
  74 # sources from the main LLVM project repositories.  The "staging" tree
  75 # is where local work is done.  A set of changes resides there waiting
  76 # to be moved upstream.  The "commit" tree is where changes from
  77 # "staging" make their way upstream.  Individual incremental changes
  78 # from "staging" are applied to "commit" and committed upstream after
  79 # a successful build and test run.  A successful build is one in which
  80 # testing results in no more failures than seen in the testing of the
  81 # "official" tree.
  82 #
  83 # A build may be invoked as such:
  84 #
  85 # llvmbuild --src=~/llvm/commit --src=~/llvm/staging
  86 #   --src=~/llvm/official --branch=trunk --branch=tags/RELEASE_28
  87 #   --build=debug --build=release --build=paranoid
  88 #   --prefix=/home/greened/install --builddir=/home/greened/build
  89 #
  90 # This will build the LLVM ecosystem, including LLVM, Clang, llvm-gcc,
  91 # gcc 4.5 and dragonegg, putting build results in ~/build and
  92 # installing tools in ~/install.  llvmbuild creates separate build and
  93 # install directories for each source/branch/build flavor.  In the
  94 # above example, llvmbuild will build debug, release and paranoid
  95 # (debug+checks) flavors of the trunk and RELEASE_28 branches from
  96 # each source tree (official, staging and commit) for a total of
  97 # eighteen builds.  All builds will be run in parallel.
  98 #
  99 # The user may control parallelism via the --jobs and --threads
 100 # switches.  --jobs tells llvmbuild the maximum total number of builds
 101 # to activate in parallel.  The user may think of it as equivalent to
 102 # the GNU make -j switch.  --threads tells llvmbuild how many worker
 103 # threads to use to accomplish those builds.  If --threads is less
 104 # than --jobs, --threads workers will be launched and each one will
 105 # pick a source/branch/flavor combination to build.  Then llvmbuild
 106 # will invoke GNU make with -j (--jobs / --threads) to use up the
 107 # remaining job capacity.  Once a worker is finished with a build, it
 108 # will pick another combination off the list and start building it.
