------- Comment #1 from tjruwase at google dot com 2009-07-16 19:24 ------- The problem is that mudflap avoids instrumenting synthetic functions, i.e DECL_ARTIFICIAL(decl) . Since cloned functions are synthetic functions, they are not instrumented by the 2nd mudflap pass.
A possible fix would be for mudflap to determine that a synthetic function is actually a clone of a non synthetic function. Unfortunately it is not obvious to me how to obtain this information, since the relevant field is cleared immediately after use. For example, cgraph_node(fndecl)->clone_of which points to the cgraph_node of the original function is cleared once the clone is materialized in cgraph_materialize_clone() and save_inline_function_body(). Is there a way to identified cloned functions after materialization ?. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40778
