Subject: If we're searching for a symbol reference to pretty-print a scattered relocation... 
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=b28bdbf8468e728501828fd41b3f2dba8db62efa;p=oota-llvm.git

If we're searching for a symbol reference to pretty-print a scattered relocation address, and we don't find a symbol table entry, try section begin addresses as well.
