With a fix for big endian machines. Thanks to Daniel Sanders for the debugging! Original commit message: The binaries containing the linked DWARF generated by dsymutil are not standard relocatable object files like emitted did previsously. They should be dSYM companion files, which means they have a different file type in the header, but also a couple other peculiarities: - they contain the segments and sections from the original binary in their load commands, but not the actual contents. This means they get an address and a size, but their offset is always 0 (but these are not virtual sections) - they also conatin all the defined symbols from the original binary This makes MC a really bad fit to emit these kind of binaries. The approach that was used in this patch is to leverage MC's section layout for the debug sections, but to use a replacement for MachObjectWriter that lives in MachOUtils.cpp. Some of the low-level helpers from MachObjectWriter were reused too. llvm-svn: 246673
