Compiler Project for CSc 42000 Spring 2019

Programming language is optional with no restrictions Standard Compiler Components:

• Lexer (Tokenizer)
• Parser
• Semantic Analyzer
• Code Generator (IR, probably going to use LLVM)

Status:

• Current using Python for implementation
• Libraries being used as a learning tool: rPLY, LLVM/lite Not using rPLY for Lexer and Parser
• rPLY for Lexer & Parser
• LLVM for generating machine code [?] Need to read up on LLVM after the other parts
• Current language input: Unknown because the professor hasn't told us yet. So thats cool. Will assume Pascal as input for now Pascal is the input language.

Features:

• Pascal Program
• Variable
• Assignments**(Required)** (Required)
• Writeln (done for strings)
• Addition/Subtraction
• Multiplication/Division
• TypeChecking
• Begin/End
• Symbol Table
• If/Else (Required)
• While (Required)
• And (Required)
• Procedures (Kind of) (Required)
• Declarations (Required)
• Repeat (Required)
• Goto (Required)
• Case (Required)
• Tokenizer (Kind of done?)
• Lexer ^
• Parser ^
• Code Generator/Stack Machine: I have no idea how to approach this atm. Finishing some functions before I move on to this.
