Module lc3_ensemble::ast::asm

This module holds the AST for statements from assembly source code.

For instructions that map to bytecode instructions (i.e., the hex representation of assembly instructions), see sim::SimInstr.

Useful structs in this module include:

• AsmInstr: An enum of all possible assembly source code instructions
• Directive: An enum of all possible assembly source code directives
• Stmt: The format for a single “statement” in assembly source code

Structs

• Stmt
  A “statement” in LC-3 assembly.

Enums

• AsmInstr
  An enum representing all of the possible instructions in LC-3 assembly code.
• Directive
  An enum representing all the possible directives in LC-3 assembly code.
• StmtKind
  Either an instruction or a directive.

Functions

• disassemble
  Attempts to disassemble bytecode back into assembly instructions.
• disassemble_line
  Attempts to disassemble a line of bytecode back into an assembly instruction, returning a .fill directive if not possible.
• try_disassemble_line
  Attempts to disassemble a line of bytecode back into an assembly instruction, returning None if it cannot be disassembled.
