-funfolding-update-in-place badly documented
The documentation for -funfolding-update-in-place implies it takes a numeric argument:
-funfolding-update-in-place=n
Switches on an experimental "optimisation". Switching it on makes the compiler a little keener to inline a function that returns a constructor, if the context is that of a thunk.
But in fact it does not. Either the documentation is wrong or the implementation has a bug, as compiling with -funfoling-update-in-place=10 gives an error that the flag is not recognized.
