A basic calculator constructed by Bison, Flex and LLVM. (Wiki)

Building BLC requires folloing components:

• Bison / Yacc: Generate syntax parser in C.
• Flex / Lex: Generate lexical analyzer in C.
• GCC / Clang / MSVC: Compiling C/C++ programs. (C++17 support required)
• LLVM: IR generation and executable compilation. (LLVM 9.0+ required)

Go to the src directory, make it~

cd src
make all

After the command is finished, a file named main will be generated, which is the executable after compilation.

./main
