Thanks to Daniel Sanders for the debugging!Original commit message:The binaries containing the linked DWARF generated by dsymutil are notstandard relocatable object files like emitted did previsously. They should bedSYM companion files, which means they have a different file type in theheader, but also a couple other peculiarities: - they contain the segments and sections from the original binary in theirload commands, but not the actual contents. This means they get an addressand a size, but their offset is always 0 (but these are not virtual sections) - they also conatin all the defined symbols from the original binaryThis makes MC a really bad fit to emit these kind of binaries. The approachthat was used in this patch is to leverage MC's section layout for thedebug sections, but to use a replacement for MachObjectWriter that livesin MachOUtils.cpp. Some of the low-level helpers from MachObjectWriterwere reused too.llvm-svn: 246673 List of files: /llvm-project-15.0.7/llvm/test/tools/dsymutil/Inputs/basic.macho.i386 Wed, 02 Sep 2015 16:49:13 +0000 Frederic Riss <friss@apple.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/tools/dsymutil/Inputs/basic.macho.i386#fae69e6d [dsymutil] Emit real dSYM companion binaries.The binaries containing the linked DWARF generated by dsymutil are notstandard relocatable object files like emitted did previsously.
