expression uses an assembler temporary symbol from an assignment. In this case the symbol does not have a fragment so the use of getFragment() would be NULL and caused a crash. In the case of an assembler temporary symbol we want to use the AliasedSymbol (if any) which will create a local relocation entry, but if it is not an assembler temporary symbol then let it use that symbol with an external relocation entry. rdar://9356266 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190096 91177308-0d34-0410-b5e6-96231b3b80d8
