POLYHEDRAL DATA FLOW GRAPH IR (PDFG IR) FRONT END COMPILER

Author: Tobi Goodness Popoola

Features / Overview

A compiler that detects Static Control Parts (SCoPs) in a C program and generates Polyhedral DataFlow Graph IR.

  1. Parses C program
  2. Generates the Iteration Domain component of Polyhedral DataFlow Graph IR.
  3. Generates the Execution Schedule component of the Polyhedral DataFlow Graph IR.

Documentation

Generate Documentation to see source manifest

OUTPUT_DIRECTORY       = @CMAKE_CURRENT_BINARY_DIR@/doc_doxygen/
INPUT                  = @CMAKE_CURRENT_SOURCE_DIR@/src/ @CMAKE_CURRENT_SOURCE_DIR@/docs

To specify the location for documentation edit OUTPUT_DIRECTORY in the docs/ folder.
