[gcov] Sort file info before printing it

Authored by vsk on Apr 25 2017, 5:16 PM.



The order in which GCOV file info is printed depends on the string hash
function. This makes some GCOV tests brittle, because the tests must be
updated whenever the hash function changes.

Sort the filenames before printing out the file info to solve the
problem. This should be relatively cheap.

Personally I wouldn't bother with SmallVector; you'll probably get more mileage just specifying how many entries to expect by calling vector::reserve(LineInfo.size()).

I'm sure it's all noise either way though.
