  1. Build Time ViewExtraction and Visualization Michael Godfrey, Xinyi Dong Software Architecture Group University of Waterloo

  2. Why Build Time View • Current way to understand build process • Read system description files (e.g. makefiles) • They only have static information. • Each file contains only a subset of the build. • Command scripts are hard to understand. • Read bill-of-materials (BOMs) • All BOMs are in text format.

  3. directory goals Targets/files depend on call sub-make Why Build Time View (Cont.) 153 makefiles 77 make processes

  4. BTV Toolkit • Goal • Use visual presentation for understanding of build process • Components • Build time fact extractor • GUI front-end • Analyzer

  5. Build-time fact extractor Products Dependencies Environment Commands … GUI Front-end CFM / BM Analyzer BTV Database BTV Toolkit Architecture

  6. (CC, “stage2/xgcc –Bstage2/ …”) (STAGE_PREFIX, “stage2/”) (LANGUAGES, “c gcoy c++ f77 java objc”) … (CC, “stage1/xgcc –Bstage1/…”) (STAGE_PREFIX, “stage1/”) (LANGUAGES, “c gcoy c++ f77 java objc”) … (CC, “gcc”) (LANGUAGES, “c”) … Sample 1:

  7. Comparison between BTVs • Many systems have different variants. • (e.g. for different OS and HW platform) • System evolves, so does the build process.

  8. Sample 2 – Comparing BTVs sunos linux both

  9. Future work • Enhancement of toolkit • More case studies
