# This script builds many different flavors of the LLVM ecosystem. It
|
||
|
|
# will build LLVM, Clang 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
|
||
|
|
# llvm
|
||
|
|
# tools
|
||
|
|
# clang
|
||
|
|
# staging
|
||
|
|
# dragonegg
|
||
|
|
# llvm
|
||
|
|
# tools
|
||
|
|
# clang
|
||
|
|
# commit
|
||
|
|
# dragonegg
|
||
|
|
# llvm
|
||
|
|
# tools
|
||
|
|
# clang
|
||
|
|
#
|
||
|
|
# 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
|
||
|
|
# --build=debug --build=release --build=paranoid
|
||
|
|
# --prefix=/home/greened/install --builddir=/home/greened/build
|
||
|
|
#
|
||
|
|
# This will build the LLVM ecosystem, including LLVM, Clangand
|
||
|
|
# dragonegg, putting build results in ~/build and installing tools in
|
||
|
|
# ~/install. llvm-compilers-check creates separate build and install
|
||
|
|
# directories for each source/build flavor. In the above example,
|
||
|
|
# llvmbuild will build debug, release and paranoid (debug+checks)
|
||
|
|
# flavors from each source tree (official, staging and commit) for a
|
||
|
|
# total of nine builds. All builds will be run in parallel.
|
||
|
|
#
|
||
|
|
# The user may control parallelism via the --jobs and --threads
|
||
|
|
# switches. --jobs tells llvm-compilers-checl 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
|
||
|
|
# llvm-compilers-check 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/flavor combination
|
||
|
|
# to build. Then llvm-compilers-check 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.
