[PATCH] D135340: [PGO] Make emitted symbols hidden

[Alex Brachet via Phabricator via cfe-commits]

abrachet updated this revision to Diff 470597.
abrachet added a comment.

Use sed to filter nm output instead of grep. grep exits with exit code 1 because there are no matching lines. This is expected because there are no more external symbols other than `_main` and `__mh_execute_header`, note `_foo` has been dead stripped.
