Subject: CodeGen: Let the BumpPtrAllocator free the elements of indexList
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=83eafdfffcd7fc709e4738213c3355d9b2d933b9;p=oota-llvm.git

CodeGen: Let the BumpPtrAllocator free the elements of indexList

The indexList's nodes are all allocated on a BumpPtrAllocator, so it's
more efficient to let them be freed when it goes away, rather than
deleting them directly. This is a follow up to r254794.
