David Majnemer 015ce0f68f [clang-cl] Handle -O correctly
We had multiple bugs here:
- We didn't support multiple optimization options in one argument.
  e.g. -O2y-
- We didn't correctly expand -O[12dx] to their respective options.
- We treated -O1 as clang -O1 instead of clang -Os.
- We treated -Ox as clang -O3 instead of clang -O2.  In fact, cl's -Ox
  option is *less* powerful than cl's -O2 option despite -Ox described
  as "Full Optimization".

Douglas Katzman 9535429270 Pedantically rename all Tool subclasses to be nouns, not verbs. NFC
Classes in Tools.h inherit ultimately from Tool, which is a noun,
but subclasses of Tool were named for their operation, such as "Compile",
wherein the constructor call "Compile(args...)" could be misconstrued
as actually causing a compile to happen.

Likewise various other methods were not harmonious with their effect,
in that "BuildLinker()" returned a "new namespace::Link(...)"
instead of a "new namespace::Linker(...)" which it now does.

Exceptions: Clang and ClangAs are un-renamed. Those are their rightful names.
And there is no particulary great way to name the "Lipo-er" and a few others.

Alexey Samsonov 7f2a0d2c04 [Sanitizers] Provide better diagnostic for sanitizers unsupported for target triple.
Introduce ToolChain::getSupportedSanitizers() that would return the set
of sanitizers available on given toolchain. By default, these are
sanitizers which don't necessarily require runtime support and are
not toolchain- or architecture-dependent.

Sanitizers (ASan, DFSan, TSan, MSan etc.) which cannot function
without runtime library are marked as supported only on platforms
for which we actually build these runtimes.

This would allow more fine-grained checks in the future: for instance,
we have to restrict availability of -fsanitize=vptr to Mac OS 10.9+
(PR23539).

Update test cases accrodingly: add tests for certain unsupported
configurations, remove test cases for -fsanitize=vptr + PS4
integration, as we don't build the runtime for PS4 at the moment.

This change was first submitted as r239953 and reverted in r239958.
The problem was and still is in Darwin toolchains, which get the
knowledge about target platform too late after initializaition, while
now we require this information when ToolChain::getSanitizerArgs() is
called. r240170 works around this issue.

Douglas Katzman 84a7564b28 Add nominal support for 'shave' target.
This change passes through C and assembler jobs to Movidius tools by
constructing commands which are the same as ones produces by the examples
in the SDK. But rather than reference MV_TOOLS_DIR to find tools,
we will assume that binaries are installed wherever the Driver would
find its native tools. Similarly, this change assumes that -I options
will "just work" based on where SDK headers get installed, rather than
baking into the Driver some magic paths.

Compiler-rt's Profiling library isn't part of the stdlib, so -nostdlib
shouldn't prevent it from being linked. This makes Darwin behave like
other toolchains, and link in the profile runtime irrespective of
-nostdlib, since the resulting program can't be run unless you link
this.

I've also added a test to show that other toolchains already behave
like this.

Now that CloudABI's target information and header search logic for Clang

support for CloudABI's linker.

CloudABI uses Binutils ld, although there is some work to use lld
instead. This means that this code is largely based on what we use on
FreeBSD. There are some exceptions, however:

- Only static linking is performed. CloudABI does not support any
  dynamically linked executables.
- CloudABI uses compiler-rt, libc++ and libc++abi unconditionally. Link
  in these libraries instead of using libgcc_s, libstdc++, etc.
- We must ensure that the .eh_frame_hdr is present to make C++
  exceptions work properly.

Bob Wilson 14ebd851d9 Do not force "-static" for aarch64 iOS kernel/kext assembly code.
Somehow a check for aarch64 was added to the Darwin toolchain's
isKernelStatic function as part of the initial commit for Apple's
arm64 target (r205100). That check was not in any of Apple's internal
code and no one here knows where it came from. It has been harmless
because "-static" does not change much, if anything, for arm64 iOS code,
but it makes no sense to keep this check.

Samuel Antao c909c9918f Fix clash of gcc toolchains in hexagon driver regression tests.
If clang was configured with a custom gcc toolchain (either by using GCC_INSTALL_PREFIX in cmake or the equivalent configure command), the path to the custom gcc toolchain path takes precedence to the one specified by -ccc-install-dir. This causes several regression tests to fail as they will be using an unexpected path. Adding the switch --gcc-toolchain="" in each test command is not enough as the hexagon toolchain implementation in the driver is not evaluating this argument. This commit modifies the hexagon toolchain to take the --gcc-toolchain="" argument into account when deciding the toolchain path, similarly to what is already done for other targets toolchains. Additionally, the faulty regression tests are modified in order to --gcc-toolchain="" be passed to the commands.

Change the LC_ID_DYLIB of ASan's dynamic libraries on OS X to be set to "@rpath/libclang_rt.asan_osx_dynamic.dylib" and similarly for iossim. Clang driver then sets the "-rpath" to be the real path to where clang currently has the dylib (because clang uses the relative path to its current executable). This means if you move the compiler or install the binary release, -fsanitize=address will link to the proper library.

Saleem Abdulrasool 543a78b55e Driver: add CrossWindowsToolChain
This is a very basic toolchain.  It supports cross-compiling Windows (primarily
inspired by the WoA target).  It is meant to use clang with the LLVM IAS and a
binutils ld-compatible interface for the linker (eventually to be lld).  It does
not perform any "standard" GCC lookup, nor does it perform any special
adjustments given that it is expected to be used in an environment where the
user is using MSVCRT (and as such Visual Studio headers) and the Windows SDK.
The primary runtime library is expected to be compiler-rt and the C++
implementation to be libc++.

It also expects that a sysroot has been setup given the usual Unix semantics
(standard C headers in /usr/include, all the import libraries available in
/usr/lib).  It also expects that an entry point stub is present in /usr/lib
(crtbegin.obj for executables, crtbeginS.obj for shared libraries).

The entry point stub is responsible for running any GNU constructors.

Zachary Turner 10d75b2f95 Make a good guess about where MSVC and Windows SDK libraries are for linking.
When a user has not configured a standard Visual Studio environment
by running vcvarsall, clang tries its best to find Visual Studio
include files and executables anyway.  This patch makes clang also
try to find system and Windows SDK libraries for linking against,
as well.

Zachary Turner 0eaf8fc4ac Resubmit "Improve Windows toolchain support for non-standard environments."
This resubmits change r220226.  That change broke the chromium
build bots because chromium it ships an hermetic MSVC toolchain
that it expects clang to fallback to by finding it on the path.

This patch fixes the issue by bumping up the prioritization of PATH
when looking for MSVC binaries.

Hans Wennborg e6b994eb93 Revert "Improve Windows toolchain support for non-standard environments." (r220226)
In environments where PATH was set to point to the VS installation, Clang would
override that by looking in the registry and finding the latest VS installation.

If the environment is set up to point to a VS installation, that should take
precedence.

Reverting this until we can fix it.

Zachary Turner 63350417e1 Improve Windows toolchain support for non-standard environments.
Typically clang finds Visual Studio by the user explicitly setting
up a Visual Studio environment via vcvarsall.  But we still try to
behave intelligently and fallback to different methods of finding
Visual Studio when this is not done.  This patch improves various
fallback codepaths to make Visual Studio locating more robust.

Specifically, this patch:

* Adds support for searching environment variables for VS 12.0
* Correctly locates include folders for Windows SDK 8.x (this was
  previously broken, and would cause clang to error)
* Prefers locating link.exe in the same location as cl.exe.  This
  is helpful in case another link.exe is in the path earlier than
  Visual Studio (e.g. GnuWin32)
* Minor cleanup in the registry reading code to make it more
  robust in the presence of long pathnames.

Chandler Carruth c44f4d44e6 Significantly fix Clang's header search for Ubuntu (and possibly other
modern Debian-based distributions) due to on-going multiarch madness.

It appears that when the multiarch heeader search support went into the
clang driver, it went in in a quite bad state. The order of includes
completely failed to match the order exhibited by GCC, and in a specific
case -- when the GCC triple and the multiarch triple don't match as with
i686-linux-gnu and i386-linux-gnu -- we would absolutely fail to find
the libstdc++ target-specific header files.

I assume that folks who have been using Clang on Ubuntu 32-bit systems
have been applying weird patches to hack around this. I can't imagine
how else it could have worked. This was originally reported by a 64-bit
operating system user who had a 32-bit crosscompiler installed. We tried
to use that rather than the bi-arch support of the 64-bit compiler, but
failed due to the triple differences.

I've corrected all the wrong orderings in the existing tests and added
a specific test for the multiarch triple strings that are different in
a significant way. This should significantly improve the usability of
Clang when checked out vanilla from upstream onto Ubuntu machines with
an i686 GCC installation for whatever reason.

Bob Wilson 9e6e0751b3 Support LIBRARY_PATH on all Darwin targets.
r197490 changed the behavior of LIBRARY_PATH to try to match GCC's behavior
for cross compilers and make clang work better on "bare metal" targets.
Unfortunately that change is breaking a number of MacPorts projects because
the LIBRARY_PATH environment variable is being ignored when compiling on a
64-bit host for a 32-bit target. Because the host and target architectures
differ, isCrossCompiling returns true. This does not make sense for Darwin,
where multiple architectures are supported natively via "fat" Mach-O slices
and where development is generally done against SDKs regardless. This patch
fixes the problem by overriding isCrossCompiling to return false for Darwin
toolchains.

Tim Northover 40956e64f2 AArch64: update Clang for merged arm64/aarch64 triples.
The main subtlety here is that the Darwin tools still need to be given "-arch
arm64" rather than "-arch aarch64". Fortunately this already goes via a custom
function to handle weird edge-cases in other architectures, and it tested.

I removed a few arm64_be tests because that really isn't an interesting thing
to worry about. No-one using big-endian is also referring to the target as
arm64 (at least as far as toolchains go). Mostly they date from when arm64 was
a separate target and we *did* need a parallel name simply to test it at all.
Now aarch64_be is sufficient.

Simon Atanasyan 60280b4e65 [Driver] Do not lose already detected set of toolchain's multilibs while
iterating over different library path suffixes and different library versions.

To find the most appropriate library for the given command line flags we
iterate over a set of disk paths. Before probe each path the already
detected set of multilibs are cleared. If the set of paths contains
existing paths which do not satisfy command line flags or do not contain
necessary libraries and object files at all we might lose found multilibs.

The patch updates variables which hold detected multilibs if we really find
a new multilib matches command line flags.
