This renames variable name to reflect initial undefined symbols that are
defined by the linker -u option.
This doesnot change any functionality in lld, and updates code to reflect
Nick's comment.
llvm-svn: 184682
This change moves the functionality of undefinedSymbols that were created in
ELFTargetInfo into TargetInfo. Looks like MachO/Windows use similiar options
like in ELF for creating undefined symbols when the linker is invoked.
Address comment from Ruiu.
(No change in functionality, except moving the functionality from ELF to
TargetInfo, so that multiple architectures can use the same)

Extract atom definitions as Atoms.h so that we can use them in other files.
Also applied clang-format to Atoms.h.

This is the first patch toward full DLL support. With this patch, lld can
read .lib file for a DLL.

This change adds functionality to add more sections like .gcc_except_table,
.data.rel.local, .data.rel.ro into the default section map, so that they are
all merged into appropriate output sections.
This also makes c++ static binaries comparable to what you get with the default
linker.
Adds a test for testing the functionality.

With this patch, it can now resolve relocations in the same output file.
"Hello world" program does not still work because call to the DLL routine
is not supported yet.

Archive file in Windows has file extension of ".lib" but the file format is
in fact the same as Unix. It's an ar archive holding multiple .obj files.
The existing archive reader can read .lib files.

Summary:
COFFReference class is defined to represent relocation information for
COFFDefinedAtom, as ELFReference for ELFDefinedAtom. ReaderCOFF can now
read relocation entries and create COFFReferences accordingly.
I need to make WriterPECOFF to handle the relocation references created by
the reader, but this patch is already big, so I think it's probably better
to get it reviewed now.

Architecture specific code should reside in architecture specific directory
not in Atom. Looks like there are no efforts being made at this moment to
support ARM, so let's remove it for now.

The yaml reader is not specific to any file format. This patch moves
it to TargetInfo and makes validate a non virtual interface so that it
can be constructed from a single location.
The same method will be used to create a reader for llvm bitcode
files.
llvm-svn: 183740
Split FileCOFF's constructor into mainly two private methods.
One method is responsible to iterate over symbol tables, and other
method is to atomize defined atoms. This is for readability and
no changes in functionality.

- Split createAtom() in lib/ReaderWriter/ELF/File.h into small methods.
- Added comments to code in other methods.
No functionality changes.
