The DWARF5 specification says(Appendix F.1): "The sections that do not require relocation, however, can be written to the relocatable object (.o) file but ignored by the linker or they can be written to a separate DWARF object (.dwo) file that need not be accessed by the linker." The first part describes a single file split DWARF feature and there is no way to trigger this behavior atm. Fortunately, no many changes are required to keep *.dwo sections in a .o, the patch does that. Differential revision: https://reviews.llvm.org/D52296 llvm-svn: 346837
