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.

This fixes a recent regression (r183338). Stripped elf files (like installed
crtn.o for example), are not required to have a symbol table. Handle that
correctly.

llvm-svn: 183573

lld can now output a valid Windows executable with a text section that does nothing
but just returns immediately. It's not able to handle relocations, symbol tables,
data sections, etc, so it still can't do anything practical, though.

This is the parser for the ENTRY command. Note that because the parsing result
is currentlyd discarded, lld can parse but just ignore the command.

Users can override the default value of the dynamic linker to be set to the
one that appears in the command line. The path can even be empty!. 

Added a test for the option.

Add WinLinkDriver and connect it to the existing COFF reader. Remaining
parts are still stubs, so while it can now read a COFF file, it still
cannot link or output PE/COFF files yet.

so that their names are hidden.

This addresses comments raised by Sean/Rafael.

only if they are relative. This removes the FIXME when the
relocations are being emitted and checks if the relocation
is relative and only then populates the addend information.

I couldnt add a testcase for this as llvm-readobj lacks     
functionality of printing dynamic relocations.              

When the functionality is added, remove the commented lines
from elf/ifunc.test to test functionality.

llvm-svn: 182077

This patch splits X86_64Target specific code so that 
the dynamic atoms and the Relocation handlers are in seperate 
files for easier maintenace. The files are sure to grow and this 
makes it easier to work with.
