Extended Description

DFR is not adapted to work with grouping of LaC functions.
The IS_NEEDED flag is only reset on the fundef spine. This
may cause both non-removal of dead functions and worse removal
of alive ones. The latter is because the tracking mechanism
does not follow functions that are already alive. If they call
a function that is new and hence still marked dead it will not
be marked alive and hence disposed off, thus leaving the AST in
an inconsistent state.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
