Alter the update method for an application instrumented for profile
feedback based optimization. The @var{method} argument should be one of
-@samp{single} or @samp{atomic}. The first one is useful for single-threaded
-applications, while the second one prevents profile corruption by emitting
-thread-safe code.
+@samp{single}, @samp{atomic} or @samp{prefer-atomic}.
+The first one is useful for single-threaded applications,
+while the second one prevents profile corruption by emitting thread-safe code.
@strong{Warning:} When an application does not properly join all threads
(or creates an detached thread), a profile file can be still corrupted.
+Using @samp{prefer-atomic} would be transformed either to @samp{atomic},
+when supported by a target, or to @samp{single} otherwise. The GCC driver
+automatically selects @samp{prefer-atomic} when @option{-pthread}
+is present in the command line.
