[ELF] Move `# REQUIRES:` line to the top llvm-svn: 335625

# REQUIRES: mips
[ELF][MIPS] Set GP0 value to zero in case of relocatable object generation LLD does not update relocations addends when generate a relocatable object. That is why we should not write a non-zero GP0 value into the .reginfo and .MIPS.options sections. And we should not accept input object files with non-zero GP0 value because we cannot handle them properly. llvm-svn: 282716

[ELF][MIPS] Do not accept non-zero GP0 value for relocatable object only Follow-up to r282716. Reject input files with non-zero GP0 value only in case of relocatable object generation. In other case we can handle arbitrary GP0 value so it does not have a sense to make the restriction so wide. llvm-svn: 283194

# DUMP: SYMBOL TABLE:
[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
