[yaml2obj][ELF] Don't explicitly set `Binding` with STB_* Instead, just have 3 sub-lists, one for each of {STB_LOCAL,STB_GLOBAL,STB_WEAK}. This allows us to be a lot more explicit w.r.t. the symbol ordering in the object file, because if we allowed explicitly setting the STB_* `Binding` key for the symbol, then we might have ended up having to shuffle STB_LOCAL symbols to the front of the list, which is likely to cause confusion and potential for error. Also, this new approach is simpler ;) llvm-svn: 184506 2013-06-21 08:27:50 +08:00			`Global:`

[yaml2obj][ELF] Allow expressing undefined symbols. Previously we unconditionally enforced that section references in symbols in the YAML had a name that was a section name present in the object, and linked the references to that section. Now, permit empty section names (already the default, if the `Section` key is not provided) to indicate SHN_UNDEF. llvm-svn: 184513 2013-06-21 09:11:48 +08:00			`- Name: undefined_symbol`
