Scale Design Focus

• Designed to be modular
• Uses object technology
• Allows easy reordering of existing transformations
• Allows easy addition of new transformations
• Designed to be flexible
• Allows lowering to be performed at different stages:
  • front end
  • Clef AST
  • Scribble CFG
  • back end
• Maintains both high level and lower level forms
• Annotations to add non-essential but useful information
• Either single module or multi-module compilation
• Designed to aid experiments
• Easy collection of statistics
• Powerful regression testing system

Scale Project Goals

• Provide a powerful framework to support research into compiler optimizations
  • e.g., Type-based alias analysis
• Gather empirical results on new ideas
• Compile multiple procedure-oriented languages
• Target multiple architectures
