[PATCH] D62541: Adding a function for setting coverage output file.

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

There should be a test case.



================
Comment at: compiler-rt/lib/profile/InstrProfiling.h:161
 
+void __llvm_profile_set_file_object(FILE *File);
+
----------------
Document this interface. Also mention that when file descriptor is provided by the client, profiling runtime won't perform profile merging.

With this, the profile file name specified by either environment variable or command line will be ignored, so it should be documented.
