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.
