Subject:  * Make TargetLowering not crash when TargetMachine::getTargetAsmInfo() returns
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d9d07780ff0d393a34cbd57cd2b85bdd8c947a04;p=oota-llvm.git

 * Make TargetLowering not crash when TargetMachine::getTargetAsmInfo() returns
   null. This assumes that any target that does not have AsmInfo, does not
   support "LocAndDot".
