[llvm-objdump] --syms: make flags closer to GNU objdump This fixes several issues. The behavior changes are: A SHN_COMMON symbol does not have the 'g' flag. An undefined symbol does not have 'g' or 'l' flag. A STB_GLOBAL SymbolRef::ST_Unknown symbol has the 'g' flag. A STB_LOCAL SymbolRef::ST_Unknown symbol has the 'l' flag.

[llvm-objdump] Further rearrange llvm-objdump sections for compatability Summary: rL371826 rearranged some output from llvm-objdump for GNU objdump compatability, but there still seem to be some more. I think this rearrangement is a little closer. Overview of the ordering which matches GNU objdump: * Archive headers * File headers * Section headers * Symbol table * Dwarf debugging * Relocations (if `--disassemble` is not used) * Section contents * Disassembly Reviewers: jhenderson, justice_adams, grimar, ychen, espindola Reviewed By: jhenderson Subscribers: aprantl, emaste, arichardson, jrtc27, atanasyan, seiya, llvm-commits, MaskRay Tags: #llvm Differential Revision: https://reviews.llvm.org/D68066 llvm-svn: 373671

[llvm-objdump] -d: print `00000000 <foo>:` instead of `00000000 foo:` The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier. `.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive. Without `-LABEL`, the CHECK line can match the `Disassembly of section` line and causes the next `CHECK-NEXT:` to fail. ``` Disassembly of section .foo: 0000000000001634 .foo: ``` Bdragon: <> has metalinguistic connotation. it just "feels right" Reviewed By: rupprecht Differential Revision: https://reviews.llvm.org/D75713

[ELF][MIPS] Support GOT entries for non-preemptible symbols with different addends There are two motivations for this patch. The first one is a preparation for support MIPS TLS relocations. It might sound like a joke but for GOT entries related to TLS relocations MIPS ABI uses almost regular approach with creation of dynamic relocations for each GOT enty etc. But we need to separate these 'regular' TLS related entries from MIPS specific local and global parts of GOT. ABI declare simple solution - all TLS related entries allocated at the end of GOT after local/global parts. The second motivation it to support GOT relocations for non-preemptible symbols with addends. If we have more than one GOT relocations against symbol S with different addends we need to create GOT entries for each unique Symbol/Addend pairs. So we store all MIPS GOT entries in separate containers. For non-preemptible symbols we have to maintain two data structures. The first one is MipsLocal vector. Each entry corresponds to the GOT entry from the 'local' part of the GOT contains the symbol's address plus addend. The second one is MipsLocalMap. It is a map from Symbol/Addend pair to the GOT index. Differential Revision: http://reviews.llvm.org/D21297 llvm-svn: 273127
