* Simplify the handling of iterators in ObjectFile.Rafael Espindola2014-01-30
| | | | | | | | | | | | None of the object file formats reported error on iterator increment. In retrospect, that is not too surprising: no object format stores symbols or sections in a linked list or other structure that requires chasing pointers. As a consequence, all error checking can be done on begin() and end(). This reduces the text segment of bin/llvm-readobj in my machine from 521233 to 518526 bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200442 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Make pubnames header printing similar to unit header printingDavid Blaikie2013-11-01
| | | | | | | | | | | | | | | In a failed attempt to allow the gnu-public-names.ll test case to not hardcode the size of the unit that the pubnames section referred to I've at least managed to have unit headers and pubnames headers print out in a similar style. This failed to achieve the desired goal because the header in a unit specifies the length of the unit without the length element of the header whereas the length in the pubnames includes this element, so the numbers are off by 4 bytes. I don't know of any arithmetic powers in FileCheck so the test case can't simply say "CU_LENGTH + 4". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193872 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Wrap section data and relocs together for dwarf dumping supportDavid Blaikie2013-09-23
| | | | | | | | | | | | | | | | | | This is a small step that may enable some simplifications in producer (DWARFContext) and consumer (DWARFCompileUnit and other places) by making a more complete abstraction around the data and relocations for a section. Small initial steps could include simple changes such as passing the pair to DWARFCompileUnit's ctor rather than passing the data and relocs separately. I don't intend to pursue any such changes immediately, however. The motivation for doing this now is that type unit dumping will need to deal with these data+reloc pairs moreso than the existing dumping support has needed to associate the data as type unit sections are named the same (debug_types) and comdat group folded. So to implement dumping and reloc handling we'll need a mapping of section->data+relocs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191209 91177308-0d34-0410-b5e6-96231b3b80d8
