Driver: Stop linking to C++ when using sanitizers on Darwin
Sanitizers on Darwin are built as dynamic libraries, not static libraries.
Sanitizers will have their C++ dependency satisfied internally (LC_LOAD_DYLIB)
in the libclang_rt dylib. As long as the sanitizers stay dynamic and not static,
linking against C++ when enabling a sanitizer becomes over linkage.

MASM (ML.exe and ML64.exe) and older versions of MSVC (CL.exe) support a
flag called /Zd which is more-or-less -gline-tables-only.
It seems nicer to support this flag instead of exposing
-gline-tables-only.

Add OCL option -cl-no-signed-zeros to driver options.
Also added to opencl.cl testcases.

Summary:
Raise an error if you're using a CUDA installation that's too old for
the requested architectures. In practice, this means that you need a
CUDA 8 install to compile for sm_6*.

Summary: This change exposes the recently added LEON CPUs (D19359) in the LLVM Sparc backend to Clang, allowing the cpu's to be selected using the -mcpu flag.

Allow -cl-std and other standard -cl- options from cc1 to driver.
Added a test for the options moved.

This reverts commit r269709.
r262285 changed this deliberately so that the test would not be
sensitive to which binaries are in the same directory as clang.
See the commit message of that commit for more background.

The PIC and PIE levels are not independent. In fact, if PIE is defined
it is always the same as PIC.
This is clear in the driver where ParsePICArgs returns a PIC level and
a IsPIE boolean. Unfortunately that is currently lost and we pass two
redundant levels down the pipeline.
This patch keeps a bool and a PIC level all the way down to codegen.
llvm-svn: 273566
We do pass -pic-level to cc1 when targeting darwin. Given that codegen
itself doesn't use it, the only difference is whether __PIE__ and
__pie__ are defined.

Add support for /Ob1 (and equivalent -finline-hint-functions), which enable
inlining only for functions marked inline, either explicitly (via inline
keyword, for example), or implicitly (function definition in class body,
for example).
This works by enabling inlining pass, and adding noinline attribute to
every function not marked inline.

This mirrors the many other -i*after options to insert a new system search
directory at the end of the search path. This makes it possible to actually
inject a search path after the resource dir. This option is similar in spirit
to the /imsvc option in the clang-cl driver. This is needed to properly use the
driver for Windows targets where the clang headers wrap some of the system
headers.
This concept is actually useful on other targets (e.g. Linux) and would be
really easy to support on the core toolchain.

Fix a regression which forbids using -std=cl|CL1.1|CL1.2|CL2.0 in driver.
Allow -std and -cl-std={cl|CL}{|1.1|1.2|2.0}.

Some GCC 5 installations store the libstdc++ includes and GCC-specific files in paths without
the minor part of the version number, such as
/usr/include/c++/5
/usr/lib64/gcc/x86_64-suse-linux/5

This is the last patch required to support compilation for Intel MCU target (e.g. Intel(R) Quark(TM) micro controller D 2000).
When IAMCU triple is used:
* Use IAMCU linker output format
* Link with IAMCU crt objects
* Link with IAMCU libraries

This is the second patch required to support compilation for Intel MCU target (e.g. Intel(R) Quark(TM) micro controller D 2000).

* Recognize and use IAMCU GCC toolchain
* Set up include paths
* Forbid C++

Summary:
Previously if you did e.g.
$ clang -march=haswell -x cuda foo.cu
we would pass "-march=haswell -march=sm_20" down to the ptxas tool.
This causes it to assert, and rightly so!

The reason is that this (a) seems to work just fine and (b) useful when building stuff with
sanitizer+coverage, but need to exclude the sanitizer for a particular source file.

The two patches together enable clang to support targets like
"x86_64-pc-linux-musl" and build binaries against musl-libc instead of
glibc. This make it easy for clang to work on some musl-based systems
like Alpine Linux and certain flavors of Gentoo.

Summary:
The validity of ABI/CPU pairs is no longer checked on the fly but is
instead checked after initialization. As a result, invalid CPU/ABI pairs
can be reported as being known but invalid instead of being unknown. For
example, we now emit:
error: ABI 'n32' is not supported on CPU 'mips32r2'
instead of:
error: unknown target ABI 'n64'

GCC still permits enabling the SjLj EH model. This is something which can be
done on various targets. Hoist the -fsjlj-exceptions option into the driver and
pass it through. This allows one to opt into the alternative EH model while
retaining the default to be the target's default.

Summary:
Android target triples can include a version number in the abi field
(e.g. 'aarch64-linux-android21'), used for checking for availability.
However, the driver was searching for toolchain binaries using the
passed in triple as a prefix.
