Subject: Teach -callgraph to always print the callgraph (as the
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e65d39a42ccb63c8b883db0c466cc43f42d83fff;p=oota-llvm.git

Teach -callgraph to always print the callgraph (as the
description says it does), not just when -analyze is
used as well.  This means printing to stderr, so adjust
some tests.
