Michael Gottesman ebdb0cf646 Add a small utility called bisect that enables commandline bisecting on a counter. This is something that I have found to be very useful in my work and I wanted to contribute it back to the community since several people in the past have asked me for something along these lines. (Jakob, I know this has been a while coming ; )] The way you use this is you create a script that takes in as its first argument a count. The script passes into LLVM the count via a command line flag that disables a pass after LLVM has run after the pass has run for count number of times. Then the script invokes a test of some sort and indicates whether LLVM successfully compiled the test via the scripts exit status. Then you invoke bisect as follows: bisect --start=<start_num> --end=<end_num> ./script.sh "%(count)s" And bisect will continually call ./script.sh with various counts using the exit status to determine success and failure. llvm-svn: 214610		2014-08-02 01:39:08 +00:00
