Todd Fiala 6ce5b63019 Updated ObjectFileELF tests to include more varaints.
Removed the distribution EXEs from FreeBSD and Ubuntu.
Added a hello-world .cpp file, and compiled it for
several platform/compiler variants:

Ubuntu 14.04 x86_64, clang 3.5 (the ubuntu1 3.5 pre variant)
Ubuntu 14.04 x86_64, gcc 4.8.2
FreeBSD 10.0 x86_64, clang 3.3
FreeBSD 10.0 x86_64, gcc 4.7.3
NetBSD 6.1 x86_64, gcc 4.5.3

I also added the NetBSD expected architecture and triple.
Note I have NetBSD not appending the version info to the
OS name, in contrast to FreeBSD.

Justin Holewinski b926d9d446 [NVPTX] Fix handling of ldg/ldu intrinsics.
The address space of the pointer must be global (1) for these intrinsics.  There must also be alignment metadata attached to the intrinsic calls, e.g.

%val = tail call i32 @llvm.nvvm.ldu.i.global.i32.p1i32(i32 addrspace(1)* %ptr), !align !0

!0 = metadata !{i32 4}

Chandler Carruth dd6470a9dd [x86] Fix a miscompile in the new shuffle lowering uncovered by
a bootstrap.

for the high bytes instead of zero. The fix is fairly obvious.

Nick Kledzik 3f69076278 [mach-o] refactor x86_64 relocation handling.
This is first step in reworking how mach-o relocations are processed.
The existing KindHandler is going to become a delgate/helper object for
processing architecture specific references.  The KindHandler knows how
to convert mach-o relocations into References and back, as well, as fixing
up the content the relocation is on.

One of the messy things about mach-o relocations is that they sometime 
come in pairs, but the pairs still convert to one lld::Reference. So, the
conversion has to detect pairs (arch specific) and change the stride.

David Majnemer dad0a645a7 IR: Add COMDATs to the IR
This new IR facility allows us to represent the object-file semantic of
a COMDAT group.

COMDATs allow us to tie together sections and make the inclusion of one
dependent on another. This is required to implement features like MS
ABI VFTables and optimizing away certain kinds of initialization in C++.

This functionality is only representable in COFF and ELF, Mach-O has no
similar mechanism.

Reid Kleckner 3260478c10 cmake: Don't do anything for LLVM_ENABLE_ASSERTIONS=OFF
By default, CMake will set NDEBUG in Rel* builds and leave it off in
debug builds, so we shouldn't need to do anything ourselves.

Before this change, it was possible to a Debug build without assertions
(aka Debug-Asserts in the autoconf system) by configuring with
-DLLVM_ENABLE_ASSERTIONS=OFF, but this configuration isn't very useful.
You can still get the same effect by explicitly adding -DNDEBUG to
CFLAGS.

Julien Lerouge a67d14f5a3 lldb can interrupt waitpid, so EINTR shouldn't be an error. This fixes the case
where there is no timeout. In the case where there is a timeout though, the
code is still wrong since it doesn't check that the alarm really went off.

Without this patch, I cannot debug a program that forks itself using
sys::ExecuteAndWait with lldb.

David Blaikie 66cc07b4f7 Remove 'const' from MemoryBuffers used through the SourceManager
This removes a const_cast added in r211884 that occurred due to an
inconsistency in how MemoryBuffers are handled between some parts of
clang and LLVM.

MemoryBuffers are immutable and the general convention in the LLVM
project is to omit const from immutable types as it's simply
redundant/verbose (see llvm::Type, for example). While this change
doesn't remove "const" from /every/ MemoryBuffer, it at least makes this
chain of ownership/usage consistent.

David Majnemer c57d038240 MC: Fix associative sections on COFF
COFF sections in MC were represented by a tuple of section-name and
COMDAT-name.  This is not sufficient to represent a .text section
associated with another .text section; we need a way to distinguish
between the key section and the one marked associative.

Reid Kleckner c542d37995 clang-cl: Map /EHs- to -fno-exceptions
This isn't 100% compatible with MSVC, but it's close enough.  MSVC's /EH
flag doesn't really control exceptions so much as how to clean up after
an exception is thrown.  The upshot is that cl.exe /EHs- will compile
try, throw, and catch statements with a warning, but clang-cl will
reject such constructs with a hard error.  We can't compile such EH
constructs anyway, but this may matter to consumers of the AST.

Todd Fiala b91de7861c Fix ObjectFileELF to determine architectures independent of host.
Previously ObjectFileELF was simplifying and assuming the object file it was
looking at was the same as the host architecture/triple.  This would break
attempts to run, say, lldb on MacOSX against lldb-gdbserver on Linux since
the MacOSX lldb would say that the linux elf file was really an Apple MacOSX
architecture.  Chaos would ensue.

This change allows the elf file to parse ELF notes for Linux, FreeBSD and
NetBSD, and determine the OS appropriately from them.  It also initializes
the OS type from the ELF header OSABI if it is set (which it is for FreeBSD
but not for Linux).

Added a test with freebsd and linux images that verify that 
'(lldb) image list -t -A' prints out the expected architecture for each.

Chandler Carruth 6666074876 Fix a bug in my previous patch by restoring the behavior that the fatal
error handler is only registered once.

To avoid the use of std::call_once (the obvious way to do this) I've
wrapped everything up into a managed static and done the work in
a constructor. Silly, but it should be effective.

Some out-of-tree libclang users reported this to me, and I've asked them
to put together a test case which exhibits this behavior, but I wanted
to fix things ASAP since the nature of the fix is straight forward.
