New Revision: 126136
URL: http://llvm.org/viewvc/llvm-project?rev=126136&view=rev
Log:
Add a convenience tool for doing comparison builds of the LLVM
ecosystem. This is a handy utility for checking changes before
committing them to the repository.

+# This script builds many different flavors of the LLVM ecosystem. It
+# will build LLVM, Clang, llvm-gcc, and dragonegg as well as run tests
+# on them. This script is convenient to use to check builds and tests
+# before committing changes to the upstream repository
+#
+# A typical source setup uses three trees and looks like this:
+#
+# official
+# dragonegg
+# trunk
+# gcc
+# trunk
+# llvm
+# trunk
+# tools
+# clang
+# tags
+# RELEASE_28
+# tools
+# clang
+# llvm-gcc
+# trunk
+# tags
+# RELEASE_28
+# staging
+# dragonegg
+# trunk
+# gcc
+# trunk
+# llvm
+# trunk
+# tools
+# clang
+# tags
+# RELEASE_28
+# tools
+# clang
+# llvm-gcc
+# trunk
+# tags
+# RELEASE_28
+# commit
+# dragonegg
+# trunk
+# gcc
+# trunk
+# llvm
+# trunk
+# tools
+# clang
+# tags
+# RELEASE_28
+# tools
+# clang
+# llvm-gcc
+# trunk
+# tags
+# RELEASE_28
+#
+# "gcc" above is the upstream FSF gcc and "gcc/trunk" refers to the
+# 4.5 branch as discussed in the dragonegg build guide.
+#
+# In a typical workflow, the "official" tree always contains unchanged
+# sources from the main LLVM project repositories. The "staging" tree
+# is where local work is done. A set of changes resides there waiting
+# to be moved upstream. The "commit" tree is where changes from
+# "staging" make their way upstream. Individual incremental changes
+# from "staging" are applied to "commit" and committed upstream after
+# a successful build and test run. A successful build is one in which
+# testing results in no more failures than seen in the testing of the
+# "official" tree.
+#
+# A build may be invoked as such:
+#
+# llvmbuild --src=~/llvm/commit --src=~/llvm/staging
+# --src=~/llvm/official --branch=trunk --branch=tags/RELEASE_28
+# --build=debug --build=release --build=paranoid
+# --prefix=/home/greened/install --builddir=/home/greened/build
+#
+# This will build the LLVM ecosystem, including LLVM, Clang, llvm-gcc,
+# gcc 4.5 and dragonegg, putting build results in ~/build and
+# installing tools in ~/install. llvmbuild creates separate build and
+# install directories for each source/branch/build flavor. In the
+# above example, llvmbuild will build debug, release and paranoid
+# (debug+checks) flavors of the trunk and RELEASE_28 branches from
+# each source tree (official, staging and commit) for a total of
+# eighteen builds. All builds will be run in parallel.
+#
+# The user may control parallelism via the --jobs and --threads
+# switches. --jobs tells llvmbuild the maximum total number of builds
+# to activate in parallel. The user may think of it as equivalent to
+# the GNU make -j switch. --threads tells llvmbuild how many worker
+# threads to use to accomplish those builds. If --threads is less
+# than --jobs, --threads workers will be launched and each one will
+# pick a source/branch/flavor combination to build. Then llvmbuild
+# will invoke GNU make with -j (--jobs / --threads) to use up the
+# remaining job capacity. Once a worker is finished with a build, it
+# will pick another combination off the list and start building it.
