Comment (by niteria):

 I've hit a small snag trying to follow:
 https://ghc.haskell.org/trac/ghc/ticket/14779#comment:15

 I expected top level primitive strings (things of type `Addr#`) to be
 either `Lit (MachStr _)` or `Lit (MachStr _)`wrapped in any number of
 allowed `Tick t _`.

 Running the `T9583` after reverting
 f5b275a239d2554c4da0b7621211642bf3b10650, revealed top level bindings of
 the form:

 {{{
 $tT_sas7 :: Addr#
 [LclId]
 $tT_sas7
   = src<libraries/base/Data/Data.hs:(620,1)-(623,25)>
     src<libraries/base/GHC/Base.hs:1047:1-18> $tcT_sahj

 $tcT_sahj :: Addr#
 [LclId]
 $tcT_sahj = "T"#
 }}}

 This appears to be a variant of a problem from the original "allow top
 level primitive strings" patch. Changing CSE similarly to
 https://phabricator.haskell.org/D2605#inline-23997 may be what I need to
 do.
