NAME
       llvm-build - LLVM Project Build Utility

SYNOPSIS
       llvm-build [options]

DESCRIPTION
       llvm-build  is a	tool for working with LLVM projects that use the LLVM-
       Build system for	describing their components.

       At heart, llvm-build is responsible for loading,	verifying, and manipu-
       lating the project's component data. The	tool is	primarily designed for
       use in implementing build systems and tools which need  access  to  the
       project structure information.

OPTIONS
       -h, --help
	  Print	the builtin program help.

       --source-root=PATH
	  If  given,  load  the	project	at the given source root path. If this
	  option is not	given, the location of the project sources will	be in-
	  ferred from the location of the llvm-build script itself.

       --print-tree
	  Print	the component tree for the project.

       --write-library-table
	  Write	 out  the  C++	fragment which defines the components, library
	  names, and required libraries.  This	C++  fragment  is  built  into
	  llvm-config|llvm-config in order to provide clients with the list of
	  required libraries for arbitrary component combinations.

       --write-llvmbuild
	  Write	out new	LLVMBuild.txt files based on  the  loaded  components.
	  This	 is  useful  for  auto-upgrading  the  schema  of  the	files.
	  llvm-build will try to a limited extent  to  preserve	 the  comments
	  which	 were  written	in  the	original source	file, although at this
	  time it only preserves block comments	that precede the section names
	  in the LLVMBuild files.

       --write-cmake-fragment
	  Write	 out  the LLVMBuild in the form	of a CMake fragment, so	it can
	  easily be consumed by	the CMake based	build system. The  exact  con-
	  tents	 and  format of	this file are closely tied to how LLVMBuild is
	  integrated with CMake, see LLVM's top-level CMakeLists.txt.

       --write-make-fragment
	  Write	out the	LLVMBuild in the form of a Makefile  fragment,	so  it
	  can  easily be consumed by a Make based build	system.	The exact con-
	  tents	and format of this file	are closely tied to how	 LLVMBuild  is
	  integrated with the Makefiles, see LLVM's Makefile.rules.

       --llvmbuild-source-root=PATH
	  If given, expect the LLVMBuild files for the project to be rooted at
	  the given path, instead of inside the	source tree itself.  This  op-
	  tion is primarily designed for use in	conjunction with --write-llvm-
	  build	to test	changes	to LLVMBuild schema.

EXIT STATUS
       llvm-build exits	with 0 if operation was	successful. Otherwise, it will
       exist with a non-zero value.
