lli: Enable all optimizations.
$ lli -O3 ${filename-ll}
try on your machine
This command is invoking the LLVM interpreter "lli" with the "-O3" flag and a file named "filename-ll" as input.
Here is a breakdown of the command:
- "lli" is the command to launch the LLVM interpreter. The LLVM (Low Level Virtual Machine) is a compiler infrastructure project that includes tools for building, optimizing, and executing program code.
- The "-O3" flag is an optimization level setting. It indicates the highest level of optimization for the program code being executed. Optimization levels can vary from 0 (no optimizations) to 3 (aggressive optimizations).
- "${filename-ll}" is a placeholder that represents the actual filename. The "-ll" suffix suggests that the file is written in LLVM IR (Intermediate Representation), which is a low-level programming language used within the LLVM infrastructure.
When the command is executed, "lli" will interpret and execute the code in the specified file ("filename-ll") with the highest level of optimization applied ("-O3").

never run a command you are not sure if it is safe.
