5:36 PM Changeset in ghc [1dd6c53]late-lam-lift by Nicolas Frisby <nicolas.frisby@…>
cleaned-up flags to stop confusing myself SetLevels now uses strictess information to determine if arguments will become closures, this enables the -8% in cichelli and helps a bit in anna too I think the captors-interpretation plan is very nearly precise except for LNEs now I added the late-float-retry flag, it enables a rough draft in SetLevels that attempts to unpin vacuous cycles involving closure growth and fast call preservation

Change how we handle libffi I think overall the new approach is simpler. Rather than unpacking the libffi.a and putting the .o files into our libHSrts.a, we just use the libffi.a. This change also means that when compiling programs for the dyn way, they get explicitly linked against libffi.so (rather than relying on librts.so being linked against it). This might fix a problem on FreeBSD, where programs cannot find libffi.so.
