This should build a separate set of embedded runtime libraries, supporting the
option product:
{PIC, static} x { Hard-float, soft-float }
The emphasis is on ARM platforms (Cortex-M4F, Cortex-M3, Cortex-M0) but X86
variants are also built where possible.

This patch removes most of the trivial cases of weak vtables by pinning them to
a single object file.

The error reported the number of explicit operands,
but that isn't what is checked. In my case, this
resulted in the confusing errors
"Too few operands." followed shortly by
"8 operands expected, but 8 given."

This patch does not change the meaning of the program, but if something's wrong
in the linker or the compiler and the control reaches to the gap of imported
function table, it will stop immediately because of the presence of INT3. If
NOP, it'd fall through to the next call instruction, which is usually a
completely foreign function call.

The failure to demangle 'anonymous namespace' on FreeBSD is fixed (twice)
- the failure in FreeBSD's in-tree __cxa_demangle has been addressed
- FreeBSD now uses the copy of the demangler built into lldb, due to other
remaining limitations in the in-tree __cxa_demangle

We used to use std::map<IndicesVector, LoadInst*> for OriginalLoads, and when we
try to promote two arguments, they will both write to OriginalLoads causing
created loads for the two arguments to have the same original load. And the same
tbaa tag and alignment will be put to the created loads for the two arguments.
The fix is to use std::map<std::pair<Argument*, IndicesVector>, LoadInst*>
for OriginalLoads, so each Argument will write to different parts of the map.

Trying to fix test failures since earlier today.
One of the tests added in this commit is outputting test/Driver/clang_f_opts.s
which the builders that build in-tree (eg. clang-native-arm-cortex-a9) are
trying to run as a test case, causing failures.
clang_f_opts.c:
If -### doesn't emit the warning then this test probably shouldn't be in
here in the first place. Frontend maybe?
invalid-o-level.c:
Running %clang_cc1 in the Driver tests doesn't make sense because -cc1
bypasses the driver. (I'm not reverting the commit that introduced this but
please fix instead of keeping it this way.)
Reverting to fix the build failures and also so that the tests can be thought
out more thoroughly.
This reverts commit r194817.

0xffff does not mean that there are 65535 sections in a COFF file but
indicates that it's a COFF import library. This patch fixes SEGV error
when an import library file is passed to llvm-readobj.

Stop folding constant adds into GEP when the type size doesn't match.
Otherwise, the adds' operands are effectively being promoted, changing the
conditions of an overflow. Results are different when:
sext(a) + sext(b) != sext(a + b)
Problem originally found on x86-64, but also fixed issues with ARM and PPC,
which used similar code.

Even if we don't support a flag, we should be able to parse it
to provide a better error message than the current default
"error: no such file or directory: '/foo'" (which we should probably
also tweak, btw).
This also tries to clean up the test file a bit.

Up until now we were expecting that when libc++ is installed alongside
clang the headers would be in lib/, which was true if the configure
build was used and false if the cmake build was.
We've now corrected the configure build to install in include/, and
with this change we'll be able to find the correct headers with both
build systems.
llvm-svn: 194834
When using the configure build system, the libc++ headers were being
installed in lib/, whereas cmake installs them in include/. Since
include/ makes more sense for headers, we'll make both systems install
headers there.

Instead of storing the vtable offset directly in the function pointer and
doing a branch to check for virtualness at each call site, the MS ABI
generates a thunk for calling the function at a specific vtable offset,
and puts that in the function pointer.
This patch adds support for emitting such thunks. However, it doesn't support
pointers to virtual member functions that are variadic, have an incomplete
aggregate return type or parameter, or are overriding a function in a virtual
base class.

Now that FileCheck supports multiple check prefixes, we don't need to keep the

easier to use freshly-built clang with freshly-built libc++.
Basically, this makes it possible to run clang with libc++ without
having to install it, even if you don't have any version of libc++
installed in /usr/
