It is quite possible that things differ on 64bit hosts, we are staying on quite fragile ground here because in the current cost metric the benefits of inlining are very close to costs. Given the nature that function call of the wrapped function is a bit chepaer than call of the wrapper is quite correct. The decision on whether function should be inlined or not depends on many things, like overall size, ABI details etc. I see it is quite irritating for ABI checking. I am sending it for testing for x86-64 now. Perhaps we can deal with this by checking ABI with -Os that is a bit less dependent on fine grained performance decision, like we are seeing here?
