[lld][LayoutPass] An earlier commit moved the functionality so that Atoms would
...
be laid out by their ordinal overrides first, there was a bug that two atoms may
get the same override index due to which atoms were not ordered properly. This
commit fixes the problem.
Now the atoms are ordered by
- Section Position hints
- Atom override (Using layout-after/layout-before/in-group)
- Content Permissions
- Content Type
- File Ordinal
This also fixes the problem of running c++ static executables that
was broken by an earlier patch.

[lld][Core] Fix latch synchronization bug.
...
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.

This is my Driver refactoring patch.
...
The major changes are:
1) LinkerOptions has been merged into TargetInfo
2) LinkerInvocation has been merged into Driver
3) Drivers no longer convert arguments into an intermediate (core) argument
list, but instead create a TargetInfo object and call setter methods on
it. This is only how in-process linking would work. That is, you can
programmatically set up a TargetInfo object which controls the linking.
4) Lots of tweaks to test suite to work with driver changes
5) Add the DarwinDriver
6) I heavily doxygen commented TargetInfo.h
Things to do after this patch is committed:
a) Consider renaming TargetInfo, given its new roll.
b) Consider pulling the list of input files out of TargetInfo. This will
enable in-process clients to create one TargetInfo the re-use it with
different input file lists.
c) Work out a way for Drivers to format the warnings and error done in
core linking.
