An issue for the SC: horrible documentation quality of GCC

[Richard Kenner]

    Also before the *local_cprop* functions, except local_cprop_pass(),
    which is only called at toplevel from one_cprop_pass().  

Also, what does "local" mean in this context?  I'd take it as the opposite
of "global", meaning to me that this does an optimzation on a small part of
the function being compiled.  Which part?  I see no documentation of that.

Or is this just a confusing name?
