Subject: Rename DIBuilder::createNullPtrType to createUnspecifiedType and introduce
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=03ccdb5b1dbb95714f2fd86540292567c8442a6b;p=oota-llvm.git

Rename DIBuilder::createNullPtrType to createUnspecifiedType and introduce
a zero-argument createNullPtrType function for creating the canonical
nullptr type.

Differential Revision: http://llvm-reviews.chandlerc.com/D1050
