R600: Fix incorrect LDS size calculation GlobalAdderss nodes that appeared in more than one basic block were being counted twice. llvm-svn: 190078

; RUN: llc < %s -march=r600 -mcpu=redwood | FileCheck %s
; This test makes sure we do not double count global values when they are
; used in different basic blocks.

Allow aliases to be unnamed_addr. Alias with unnamed_addr were in a strange state. It is stored in GlobalValue, the language reference talks about "unnamed_addr aliases" but the verifier was rejecting them. It seems natural to allow unnamed_addr in aliases: * It is a property of how it is accessed, not of the data itself. * It is perfectly possible to write code that depends on the address of an alias. This patch then makes unname_addr legal for aliases. One side effect is that the syntax changes for a corner case: In globals, unnamed_addr is now printed before the address space. llvm-svn: 210302
