[Object] Split the ELF interface into 3 parts. * ELFTypes.h contains template magic for defining types based on endianess, size, and alignment. * ELFFile.h defines the ELFFile class which provides low level ELF specific access. * ELFObjectFile.h contains ELFObjectFile which uses ELFFile to implement the ObjectFile interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188022 91177308-0d34-0410-b5e6-96231b3b80d8

[ELF] Convert ELF.h to Expected<T>. This has two advantages: 1) We slowly move away from ErrorOr to the new handling interface, in the hope of having an uniform error handling in LLVM, eventually. 2) We're starting to have *meaningful* error messages for invalid object ELF files, rather than a generic "parse error". At some point we should include also the offset to improve the quality of the diagnostic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@287081 91177308-0d34-0410-b5e6-96231b3b80d8

Move to llvm-readobj code that is only used there. lld might end up using a small part of this, but it will be in a much refactored form. For now this unblocks avoiding the full section scan in the ELFFile constructor. This also has a (very small) error handling improvement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@244282 91177308-0d34-0410-b5e6-96231b3b80d8

Simplify iterating over program headers and detect corrupt ones. We now use a simple pointer and have range loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242669 91177308-0d34-0410-b5e6-96231b3b80d8

This reverts commit r260488 and r260489. Original messages: Revert "[readobj] Handle ELF files with no section table or with no program headers." Revert "[readobj] Dump DT_JMPREL relocations when outputting dynamic relocations." r260489 depends on r260488 and among other issues r260488 deleted error handling code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@260962 91177308-0d34-0410-b5e6-96231b3b80d8

Introduce a getAsRange helper. This requires making an error message a bit more generic, but that seems a reasonable tradeoff. Extracted from r260488 but simplified a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@260967 91177308-0d34-0410-b5e6-96231b3b80d8

Represent the dynamic table itself with a DynRegionInfo. The dynamic table is also an array of a fixed structure, so it can be represented with a DynReginoInfo. No major functionality change. The extra error checking is covered by existing tests with a broken dynamic program header. Idea extracted from r260488. I did the extra cleanups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@261107 91177308-0d34-0410-b5e6-96231b3b80d8

DYN-TABLE-SIZE: Invalid entity size
Add dynamic_table iterators back to ELF.h. In tree they are only used by llvm-readobj, but it is also used by https://github.com/mono/CppSharp. While at it, add some missing error checking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@244320 91177308-0d34-0410-b5e6-96231b3b80d8
