Sounds OK to me.

Another thing you might want to check is linkonce_odr functions - I guess you'll get an arbitrary choice between two linkonce_odr functions under LTO where they have different warn-stack-size? Maybe there's a way/place to merge and always pick the lower or upper value if there's one you think would be more right?

----------------
Nice to see the test - though I probably wouldn't bother adding this test if this behavior already falls out of more general support in the inliner and the way it already handles attributes - the general behavior is likely already tested elsewhere? (though it'd be good to confirm that either in tests and/or the inliner code itself)

my original question was to confirm that the inliner already had accounted for this situation in a way that was desirable & it looks like/sounds like it is.
