Possible Bugs in cgraphunit.c

[Nicholas Krause]

Greetings,
Seems that the extend_trucks return values are not returned when called 
in both,
cnode::assemble_thunks_and_aliases and cnode::create_wrapper. I'm not sure
if this is a set of edge case bugs or there was a reason for this. Seems 
not as its
checked in the third function caller in the file, cgraph_node::analyze.
Not sure if my assumptions are correct so I'm asking if there isn't 
another reason
for this as the code seems to have at least directly no reason for it,

Nick
