| CoreDoStrictness
| CoreDoSpecialising
- | CoreDoDeforest
| CoreDoFoldrBuildWorkerWrapper
| CoreDoFoldrBuildWWAnal
\end{code}
| MaxSimplifierIterations Int
- | KeepSpecPragmaIds -- We normally *toss* Ids we can do without
- | KeepUnusedBindings
-
| SimplNoLetFromCase -- used when turning off floating entirely
| SimplNoLetFromApp -- (for experimentation only) WDP 95/10
| SimplNoLetFromStrictLet
-- the scrutinee of a case expression, so we should
-- apply the scrutinee discount when considering inlinings.
-- See SimplVar.lhs
+
+ | SimplCloneBinds -- This flag controls whether the simplifier should
+ -- always clone binder ids when creating expression
+ -- copies. The default is NO, but it needs to be turned on
+ -- prior to floating binders outwards.
