Don't be over eager in evaluating a subtraction with a weak symbol. In a subtraction of the form A - B, if B is weak, there is no way to represent that on ELF since all relocations add the value of a symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233139 91177308-0d34-0410-b5e6-96231b3b80d8 2015-03-24 23:48:44 +00:00			`// RUN: not llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu %s -o %t 2>&1 \| FileCheck %s`
