Usage: build_install_llvm.sh [options] -- [cmake-args]
Checkout svn sources and run cmake with the specified arguments. Used
inside docker container.
Passes additional -DCMAKE_INSTALL_PREFIX and archives the contents of
the directory to /tmp/clang.tar.gz.
Available options:
-h|--help show this help message
-b|--branch svn branch to checkout, i.e. 'trunk',
'branches/release_40'
(default: 'trunk')
-r|--revision svn revision to checkout
-p|--llvm-project name of an svn project to checkout. Will also add the
project to a list LLVM_ENABLE_PROJECTS, passed to CMake.
For clang, please use 'clang', not 'cfe'.
Project 'llvm' is always included and ignored, if
specified.
Can be specified multiple times.
-i|--install-target name of a cmake install target to build and include in
the resulting archive. Can be specified multiple times.
Required options: At least one --install-target.
All options after '--' are passed to CMake invocation.
