llvm-config

LLVM (Low-Level Virtual Machine) is a collection of modular and reusable compiler and toolchain technologies widely used in the software development industry. llvm-config is a command-line tool that provides information about the LLVM installation on your system.

1. llvm-config is typically used to extract relevant information about LLVM for developers and build systems.
2. It can be used to retrieve various configuration options and flags used during the LLVM build process.
3. This tool helps in determining the installation paths of LLVM components and libraries.
4. It provides details about the LLVM version, including the major, minor, and patch numbers.
5. llvm-config can also output the relative version of LLVM with respect to the supported C++ API.
6. It aids in querying the available targets and architectures supported by LLVM.
7. The tool provides the list of LLVM components installed, such as libraries and plugins.
8. It offers information about the LLVM build modes, e.g., debug or release.
9. llvm-config can provide the compilation flags necessary to build code using LLVM.
10. The output of llvm-config can be used within build scripts or other development tools to ensure proper integration with LLVM.
