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