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