lli

lli is a command line tool that stands for LLVM interpreter. It is a part of the LLVM project and provides a way to execute programs that are compiled using the LLVM compiler infrastructure. The main purpose of lli is to provide an execution environment for programs written in LLVM intermediate language (LLVM IR). LLVM IR is a low-level programming language that is platform-independent and used as an intermediate representation during the compilation process. lli takes LLVM IR as input and executes it directly without the need for separate compilation or linking steps. It supports just-in-time (JIT) compilation, allowing for dynamic compilation and execution of code at runtime. It provides performance analysis capabilities and enables developers to profile and optimize their code during execution. lli is highly portable and can be used on various platforms, including Linux, macOS, and Windows. It can be used to run LLVM-based tools, such as compilers, optimizers, and dynamic language interpreters. In addition to execution, lli also supports debugging features like breakpoints, stack introspection, and tracing, making it a powerful tool for development and testing.
