(where "fat" is the previous kind of LTO, throw everything in one giant module) Along the way this also refactors a number of fields which store information about whether LTO/ThinLTO are enabled to unify them all into one field through which everything is dispatched, hopefully removing a number of special cases throughout. This is intended to help mitigate #47409 but will require a backport as well, and this would unfortunately need to be an otherwise insta-stable option. 2017-12-07T14:53:49+00:00 Alex Crichton alex@alexcrichton.com 2017-12-07T01:59:33+00:00 urn:sha1:17fb43bdc61481ff754fe53e8e8fa589fb8789ee In #46382 the logic around linkage preservation with ThinLTO ws tweaked but the loop that registered all otherwise exported GUID values as "don't internalize me please" was erroneously too conservative and only asking "external" linkage items to not be internalized. Instead we actually want the inversion of that condition, everything *without* "local" linkage to be internalized. This commit updates the condition there, adds a test, and...

These statics, however, were getting gc'd by ThinLTO accidentally which later would cause linking failures. This commit updates the location we add such symbols to happen just before codegen to ensure that (a) they're not eliminated by the optimizer and (b) the optimizer doesn't even worry about them.
