clang: Compile source code into LLVM Intermediate Representation (IR).
$ clang -S -emit-llvm ${file-c} -o ${file-ll}
try on your machine
This command is using the 'clang' compiler to perform a specific operation. Let's break it down:
- 'clang' is a compiler front-end for the C, C++, and Objective-C programming languages. It is used to compile source code into executable programs.
- '-S' is a flag that tells clang to stop after compiling and generating assembly code for each input file, without assembling or linking them further.
- '-emit-llvm' is another flag that tells clang to generate LLVM intermediate representation (IR) code instead of machine code. LLVM IR is a low-level program representation that can be optimized and transformed before converting it to machine code.
- '${file-c}' and '${file-ll}' are variables that should be replaced with actual file names. '${file-c}' refers to the input C source code file, and '${file-ll}' is the desired output file name for the generated LLVM IR code.
Putting it all together, the command is instructing clang to compile the C source code file ('${file-c}'), stop after generating assembly code, and emit LLVM IR code instead of machine code. The output LLVM IR code will be saved in the file specified by '${file-ll}'.

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