[llvm-dev] With -flto, is manual inline unnecessary?

[Craig Topper via llvm-dev]

The inline keyword is a hint. The inliner calculates the cost of inlining a
function using various heuristics. If the cost is too high it won't be
inlined. The inline keyword increases the threshold that is considered too
costly.
