[PATCH] D49853: [gcov] Display the hit counter for the line of a function definition

[calixte via Phabricator via llvm-commits]

calixte created this revision.

Herald added a subscriber: llvm-commits.

Right now there is no hit counter on the line of function.
So the idea is add the line of the function to all the lines covered by the entry block.
Tests in compiler-rt/profile will be fixed in another patch.
