[PATCH] D39331: Add flags to control the -finstrument-functions instrumentation calls to __cyg_profile functions

[Hans Wennborg via Phabricator via cfe-commits]

hans created this revision.

This adds two flags:

-fno-cygprofile-exit Don't insert any calls for function exit.
-fno-cygprofile-args Don't pass any arguments to the cygprofile functions (the implementer has to figure out the caller address themselves)

These are useful for reducing the size and run-time overhead of the instrumentation.
