Hi,
I found some code in opt_prop.cxx relies on the CODEREP::Usecnt() to enable
or disable copy propagation for cse:
inside_cse = inside_cse || x->Usecnt() > 1;
This means the copy propagation are always disabled for ILOAD with mu to
default vsym if the Usecnt() is more than 1.
But I guess the usecnt of a coderep is not always corrent. Can the copy
propagation rely on this number?
