Turn on SplitSections by default
This is a general tracking bug for what is blocking us from turning on
SplitSections by default, implemented in #8405 (closed). Fixing this, and mandating use of the gold linker, will help solve #11285 (closed) (split objects make linking slow), and will make ghc-split unnecessary, mooting #9832 (closed).
I encountered some misinformation while talking to people about this feature, regarding whether or not this feature only supported by Apple-style linkers (i.e. on Mac OS X)? On IRC I heard a claim made that
--split-sections was only supported by Mac OS X. However, olsner pointed out that
-split-sections on GHC was OUR reimplementation of the feature, and likely does not work on Mac OS X. https://github.com/snowleopard/shaking-up-ghc/issues/153\#issuecomment-171078800 A later comment mentioned that
So, can we turn on this feature by default? Does it subsume split-objs? Does it work on all the tier-1 platforms? It would be nice if bgamari, olsner and co could weigh in here. Thanks!
