| This directory contains scripts that are used by the regression | 
 | tester, <http://gcc.gnu.org/regtest/> | 
 |  | 
 | The primary script is 'btest-gcc.sh'.  This is the script that is run | 
 | to actually test the compiler. | 
 |  | 
 | 'objs-gcc.sh' takes a combined tree and builds (but does not test) the | 
 | tools required for 'btest-gcc.sh'.  It is run periodically to update | 
 | the tools.  This script is followed by running 'btest-gcc.sh' using | 
 | the newly-build tools to check that they will not cause regressions. | 
 |  | 
 | 'site.exp' is what $DEJAGNU points to when the regression tester runs | 
 | these scripts. | 
 |  | 
 | 'GCC_Regression_Tester.wdgt' is a Dashboard widget that displays the | 
 | current state of the tester using Javascript.  You can use it without | 
 | needing Dashboard by pointing your web browser at | 
 | 'GCC_Regression_Tester.wdgt/widget.html', if your browser supports | 
 | and permits it. | 
 |  | 
 | Note that any changes made here need to be approved by the regression | 
 | tester's maintainer (see MAINTAINERS).  The changes will be used on | 
 | the tester's next run, so `experimental' changes are very strongly | 
 | discouraged :-). |
