Developed a compiler for ARM hardware platform, which can compile a simplified C language (Sysy2020, a custom language for the contest) into ARMv7 instructions.

Main Work

• Use Flex as a lexical analyzer and Bison as a parser to analyze the source code to generate an abstract syntax tree (AST).
• Convert the abstract syntax tree into an intermediate representation (IR), and do some machine-independent optimizations on this basis.

Technology

• C++
• Flex and Bison
• Compilation optimization techniques
