Isn't this a bit of a nuisance also directly on trunk and not only for
If I do e.g.
git blame test/Transforms/LoopUnroll/basic.ll
then every line in the file is attributed to the commit where the
testcases were added back again.
older commits are shown as well so it's not like all history is gone,
but at least blame is messed up.
For our downstream clone, we didn't merge from trunk to our
development-branch while the testcases were gone, so we never got any
conflicts at all, and since the tests were later put back I think the
situation for us now is the same as being directly on trunk.
