Implemented a compiler for MiniJava, a subset of Java.
In order to execute the produced LLVM intermediate code you should install the Clang compiler. For the testing purposes of this project clang-4.0 was used. You can install Clang by using the following command in any Linux distro:
sudo apt-get install clang-4.0
In order to compile the project you simply need to run make
make
From the main directory, execute
java Main <inputFile>
In order to run the compiled LLVM code you'll need to create an executable file
clang-4.0 <fileName> -o a.out
and then simply run it.
./a.out
Let's say we want to compile and run the following file: input/Addition.java
Firs, we need to compile our project:
make
Secondly, we want to compile input/Addition.java using our MiniJava compiler:
java Main input/Addition.java
This will produce the file Factorial.ll in the /output directory. Then we want to compile this intermediate LLVM code using Clang:
clang-4.0 output/Addition.ll -o a.out
Finally, all that is left to do is to execute the executable:
./a.out
