Presentation Transcript

  1. Presented by Rosh Dhanawade and Doug Wise The Scale Compiler

  2. SCALE-Who and Where • A Scalable Compiler for Analytical Experiments • UMASS (Amherst)-Scale Compiler Group • University of Texas (Austin)-Second University Involved

  3. SCALE-Source • Parses-C, FORTRAN, Java-byte-code • Using ANTLR, ANother Tool for Language Recognition • Outputs-C and Assembly Code • Intermediate Representation-SCRIBBLE • Architecture-TRIPS Architecture • The Tera-op, Reliable, Intelligently adaptive Processing System • Microprocessor technology being developed at the University of Texas

  4. SCALE-Architecture

  5. SCALE-Representations • AST • AST to C, AST to Scribble • Scribble-Control Flow Graph

  6. SCALE-Scribble

  7. SCALE-Uses • 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

  8. SCALE-Native Compilers: Fortran

  9. SCALE-Native Compilers: C

  10. SCALE-Known Issues • The Java-based parsers have not been thoroughly tested. • The Mips® backend is not complete. • The PowerPC® backend is not under regression test.

  11. SCALE-Future Enhancements • Constantly testing new Optimizations • Research in improving algorithms and representations behind the exiting optmizations
