From 5632fabd0a6e1f30e9cbbd6c2b6d3dce6dcc656a Mon Sep 17 00:00:00 2001
From: Chris Lattner <sabre@nondot.org>

Subject: [PATCH] eliminate the horrid AsmPrinter::getGlobalLinkName method,
 inlining it into all of its call sites and simplifying them.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81962 91177308-0d34-0410-b5e6-96231b3b80d8
