+\fB--bisect=optimization:filename\fR
+This flag is used by the automatic optimization bug bisector. It
+takes an optimization flag and a filename of a file containing a list
+of full method names, one per line. When it compiles one of the
+methods in the file it will use the optimization given, in addition to
+the optimizations that are otherwise enabled. Note that if the
+optimization is enabled by default, you should disable it with `-O`,
+otherwise it will just apply to every method, whether it's in the file
+or not.
