Subject: CodeGen: Do not add a global's address space to the folding set profile.
X-Git-Tag: llvmorg-4.0.0-rc1~6426
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=16e9b944e927c3d8a8f259306735fea37891ea1e;p=platform%2Fupstream%2Fllvm.git

CodeGen: Do not add a global's address space to the folding set profile.

It is already part of the type (which is part of the global, which is already
being added), so there's no need to do it.
