LLVM Compiler Backend

A multiple-target rush compiler backend using the LLVM framework and the Inkwell crate.

Prerequisites

In order to compile the LLVM backend, please ensure that you have a valid LLVM installation on your machine. For further information and troubleshooting, please consult the llvm-sys crate's documentation as it is used by Inkwell.

Compiling and Running rush Code

Compilation

• Prerequisite: A file ending in .rush which contains the program.
• Execute following command as it will generate the output.o file from the source program.

cargo run your-file.rush

Linking

• Since rush programs depend on some sort of standard library, linking the .o file using gcc will likely result in a valid program.
• In order to link the output.o alongside your system's C library, issue following command.

gcc output.o -o output

Running the Program

• Since the output of the previous command is a binary, it can be executed using the following command.
• The suffix containing echo ... is optional and merely prints out the program's exit-code.

./output ; echo $?
