Normally, get_callee_fndecl is called with a CALL_EXPR
as might be clear from the abort test :).

Now I don't understand your remark because when I add a location
to every CALL_EXPR by means of wrapping every CALL_EXPR in a WFL,
then get_callee_fndecl is thus called with a WFL that wraps the
CALL_EXPR.  That was the whole point no?  To *replace* *every*
CALL_EXPR with a EXPR_WITH_FILE_LOCATION, so I did :/

Now tell me I need to make an exception for get_callee_fndecl
because that would be the first of many exceptions that would
make this totally unmaintainable - or I am missing something.

/usr/src/GNU/gcc/gcc-mainline/gcc>grep get_callee_fndecl *.c
builtins.c:  tree fndecl = get_callee_fndecl (exp);
builtins.c:  tree fndecl = get_callee_fndecl (exp);
builtins.c:  tree fndecl = get_callee_fndecl (exp);
builtins.c:  fndecl = get_callee_fndecl (t);
builtins.c:  tree fndecl = get_callee_fndecl (exp);
builtins.c:  tree fndecl = get_callee_fndecl (exp);
builtins.c:      tree fndecl = get_callee_fndecl (exp);
builtins.c:      tree fndecl = get_callee_fndecl (exp);
builtins.c:  tree fndecl = get_callee_fndecl (exp);
calls.c:  fndecl = get_callee_fndecl (exp);
cgraphunit.c:   tree decl = get_callee_fndecl (*tp);
dojump.c:       tree fndecl = get_callee_fndecl (exp);
fold-const.c:     fndecl = get_callee_fndecl (arg0);
fold-const.c:         fndecl = get_callee_fndecl (arg0);
fold-const.c:     tree fndecl = get_callee_fndecl (arg0);
fold-const.c:   tree fndecl = get_callee_fndecl (t);
function.c:     fntype = get_callee_fndecl (fntype);
tree.c: tree fn = get_callee_fndecl (t);
tree.c:get_callee_fndecl (tree call)
tree-inline.c:      t = get_callee_fndecl (node);
tree-inline.c:  fn = get_callee_fndecl (t);
