AcDc Compiler

Description

  • This is a project from NTU (National Taiwan University) course, Compiler Technology of Programming Language.
  • First project is aim to
    • add multiplier and division operation in this compiler
    • let compiler can recognize multi character identifier(variable) name by alphabet string
    • use constant folding to optimize the statement

How to use?

  • You can browse Assignment1.pdf. You must run in Linux OS environment(more conveniently). When you finish the coding, use $ make command directly.
  • $ ./AcDc <input sample address> <output file address>
    • For instance: $ ./AcDc ../test/sample1.ac ./output

Something need to know first

  • It can not recognize the bottom line as identifier name.
  • It can not print negative value like $1-2=-1$ expression. Actually speaking, it can calculate correctly but it can not print it out.(I’ll check it out later.)
    • You can check constfold testbench
    • Solution and Why: In Dc Language, the bottom line represent negative symbol. You can not just use minus as negative symbol, replace it by bottom line instead.
  • It can not recognize identifier name with numbers. You can check longname.ac
  • The other testbenchs can compile from Ac language to Dc language correctly.
