We currently emit an error when trying to assemble a file with more than one section using DWARF2 debug info. This should be a warning instead, as the resulting file will still be usable, but with a degraded debug illusion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218241 91177308-0d34-0410-b5e6-96231b3b80d8
