sym_is_choice(sym) has already been checked by previous if-block:
if (sym_is_choice(sym) || (sym->flags & SYMBOL_NO_WRITE))
continue;
Hence, the following code is redundant, and the comment is misleading:
if (!sym_is_choice(sym))
continue;
/* fall through */
It always takes 'continue', never falls though.
Clean up the dead code.
