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.

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.
* There is no change in functionality *
llvm-svn: 182076
Summary:
Split buildFollowOnTable to small functions to improve
code readability and remove code duplication. No change
in functionality.

Layoutpass by ordering atoms if they appear in the override
list first and then looking at the way of ordering atoms in
the default way.
The fix also fixes issues with the sizes of the sections,
that appear in the output properly too.
The commit also adds a testcase(orderatoms-by-override.test)
to test it and fixes all the other relevant testcases.

We need to acquire a lock before signal a condition.
Otherwise threads waiting on a condition variable can
miss a signal.
Consider two threads: Thread A executing dec() and thread
B executing sync(). The initial value of _count is 1. If
these two threads are interleaved in the following order,
thread B misses the signal sent by thread A, because at the
time thread A sends a signal, B is not waiting for it.
Thread A | Thread B
| std::unique_lock<std::mutex> lock(_condMut);
| while (!(_count == 0)) {
if (--_count == 0) |
_cond_notify_all() |
| _cond.wait();
| }
Note that "wait(lock, pred)" is equivalent to "while(!pred())
wait(lock)", so I expanded it in the above example.

to the list of undefined atoms.
The processing of undefined atoms from dynamic libraries is controlled by
use-shlib-undefines command line option.
This patch also adds additional command line arguments to allow/disallow
unresolved symbols from shared libraries and mimics GNU ld behavior.

InputFile is being pulled from the Archive library to resolve a symbol.
The buffer which was being used was already being handed over to the
MemoryBuffer object and was being accessed after the hand over.
Moving it before the buffer is handed over.
