  1. This directory contains scripts that are used for identifying the
  2. patch that introduced a regression. General information about such
  3. searches is covered in http://gcc.gnu.org/bugs/reghunt.html.
  4. reg_search searches for a small time interval within a range of
  5. dates in which results for a test changed, using a binary search.
  6. The functionality for getting sources, building the component to
  7. test, and running the test are in other scripts that are run from
  8. here.
  9. reg_periodic invokes separate tools (the same scripts invoked by
  10. reg_search) over a range of dates at specified intervals.
  11. reg_test_template shows the format for the script that runs a test
  12. and determines whether to continue the search with a later or
  13. earlier date.
