Subject: unique_ptrify LoadedObjectInfo::clone
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=fcf7993d4a3956b74e9a5d70c1292dbce66bef01

unique_ptrify LoadedObjectInfo::clone

As noted in the original review, this is unused in tree & is used by
Julia... that's problematic. This API coudl easily be deleted/modified
by accident without any validation that it remains correct.
