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. 17
