 * differential:   => 2563


Comment:

 The foreign symbol name is missing. With the "prim" calling convention,
 the empty entity string doesn't get replaced with the function name "f1"
 (while it does with the "ccall" convention). Hence the "jmp" without
 target in the generated asm.

 Proposed patch: https://phabricator.haskell.org/D2563
