llvm/utils/llvmbuild
David Greene b1939d5db6 Fix the case where the number of jobs is less than the 
number of threads.  In that case make the number of threads
equal to the number of jobs and launch one jobs on each
thread.  This makes things work like make -j.

#
# 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.
