The llvm-config
command is a utility provided by the LLVM compiler infrastructure that provides information about the installed LLVM components and configuration.
When you run the llvm-config --targets-built
command, it returns a list of target architectures that have been built and are supported by the installed LLVM installation.
A target architecture refers to the specific processor and/or microarchitecture for which code can be generated by the LLVM compiler. LLVM supports a wide range of target architectures, such as x86 (32-bit and 64-bit), ARM, PowerPC, MIPS, and others.
By using the --targets-built
option with llvm-config
, you can obtain a list of these target architectures that have been built and are available for use with the LLVM compiler. This information can be useful when configuring or building software that relies on LLVM, as it allows you to determine which targets are supported and potentially optimize code generation for specific architectures.
