Subject: iterator_range: Add an llvm::make_range() helper method.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=b4dd10a72368943c4edff2562752f2e93ca8608f;p=oota-llvm.git

iterator_range: Add an llvm::make_range() helper method.

Convenience wrapper to make dealing with sub-ranges easier. Like the
iterator_range<> itself, if/when this sort of thing gets standards
blessing, it will be replaced by the official version.
