Hans Wennborg 4ae76c2692 clang-cl: make /Wall turn on both -Wall and -Wextra (PR25563)
The documentation suggests /Wall should really turn on -Wextra and any
other warnings that are not enabled by default. That would correspond
to Clang's -Weverything, but is probably not what users want.

Hopefully fix the remaining bot failure from r254927. Remove

Teresa Johnson aff223278c [ThinLTO] Option to invoke ThinLTO backend passes and importing
Summary:
Adds new option -fthinlto-index=<file> to invoke the LTO pipeline
along with function importing via clang using the supplied function
summary index file. This supports invoking the parallel ThinLTO
backend processes in a distributed build environment via clang.

Additionally, this causes the module linker to be invoked on the bitcode
file being compiled to perform any necessary promotion and renaming of
locals that are exported via the function summary index file.

Add a couple tests that confirm we get expected errors when we try to
use the new option on a file that isn't bitcode, or specify an invalid
index file. The tests also confirm that we trigger the expected function
import pass.

Artem Belevich 8601733c1c [CUDA] Make CUDA compilation usable by default.
Currently clang requires several additional command
line options in order to enable new features needed
during CUDA compilation. This patch makes these
options default.

* Automatically include cuda_runtime.h if we've found
  a valid CUDA installation.
* Disable automatic CUDA header inclusion during unit tests.
* Added test case for command line construction.
* Enabled target overloads and relaxed call checks that are
  needed in order to include CUDA headers.
* Added CUDA-7.5 installation path to the CUDA installation search list.

Artem Belevich fa11ab53c0 [CUDA] added include paths for both sides of CUDA compilation.
In order to compile a CUDA file clang must be able to find
include files for both both host and device.

This patch passes AuxToolchain to AddPreprocessingOptions and
uses it to add include paths for the opposite side of compilation.

We also must be able to find CUDA include files. If the driver
found CUDA installation, it adds appropriate include path
to CUDA headers. This can be disabled with '-nocudainc'.

- Added include paths for the opposite side of compilation.
- Added include paths to detected CUDA installation.

Tim Northover c741b04d1e ARM: fix mismatch between Clang and backend on exception type.
"-arch armv7k" is only normally used with a watchos target, but Clang doesn't
stop you from giving a "-miphoneos-version-min" option too, converting the
triple to "thumbv7k-apple-ios". In this case the backend will decide to use
SjLj exceptions, so Clang needs to agree so it can create the correct
predefines.

Fortunately, there's a handy function to make the decision for us now.

Saleem Abdulrasool 436256a713 Support Debug Info path remapping
Add support for the `-fdebug-prefix-map=` option as in GCC.  The syntax is
`-fdebug-prefix-map=OLD=NEW`.  When compiling files from a path beginning with
OLD, change the debug info to indicate the path as start with NEW.  This is
particularly helpful if you are preprocessing in one path and compiling in
another (e.g. for a build cluster with distcc).

Note that the linearity of the implementation is not as terrible as it may seem.
This is normally done once per file with an expectation that the map will be
small (1-2) entries, making this roughly linear in the number of input paths.

Addresses PR24619.

The Windows on ARM ABI recommends that FPO be disabled.  This is since the
Windows on ARM ABI uses the FP for fast stack walking.  By paying the slight
cost of the loss of registers, a much faster backtrace is possible by using the
frame pointer since the pdata need not be consulted.  Furthermore, even if pdata
is not available, you can still more easily reconstruct the stack.

Bruno Cardoso Lopes a5efe3a66b [DarwinDriver] Reapply: Use -lto_library to specify the path for libLTO.dylib
Reapply r248935.

Usually, when using LTO with a clang installation newer than the
system's one, there's a libLTO.dylib version mismatch and LTO fails. One
solution to this is to make ld point to the right libLTO.dylib by
changing DYLD_LIBRARY_PATH.

However, ld64 supports specifying the complete path to the desired
libLTO.dylib through the -lto_library option. This commit adds support
for the clang driver to use this option whenever it's capable of finding
a libLTO.dylib in clang's installed library directory. This way, we
don't need to rely on DYLD_LIBRARY_PATH nor get caught by version
mismatches.

Summary:
This new toolchain uses primarily LLVM-based tools, eg. compiler-rt, lld,

installation nor a GNU environment. Ideally, in a follow-up patch we
would like to add a new --{llvm|clang}-toolchain option (similar to
--gcc-toolchain) in order to allow the use of this toolchain with
independent Clang builds. For the time being, we use the --sysroot
option just to test the correctness of the paths generated by the
driver.

Saleem Abdulrasool d44901f21b Driver: support ARM/HF on a single toolchain
ARM EABI adds target attributes to the object file.  Amongst the attributes that
are emitted is the VFP argument passing (Hard vs Soft).  The linker is
responsible for checking these attributes and erroring on mismatches.  This
causes problems for the compiler-rt builtins when targeting both hard and
soft.  Because both of these options name the builtins compiler-rt component
the same (libclang_rt.builtins-arm.a or libclang_rt.builtins-arm-android).  GCC
is able to get away with this as it does one target per toolchain.  This
changes the naming convention for the ARM compiler-rt builtins to differentiate
between HF and Soft.  Although this means that compiler-rt may be duplicated, it
enables supporting both variants from a single toolchain.  A similar approach is
taken by the Darwin toolchain, naming the library to differentiate between the
calling conventions.

Nico Weber 4cc796a614 clang-cl: Don't warn on /bigobj flag
LLVM r217812 made it so that clang-cl implicitly creates bigobj files when
needed, independent of this flag. It looks like cl has this flag to produce obj
flags compatible with MSVS 2003's linker by default, something we don't care
about. Since clang-cl always has /bigobj behavior, don't warn that the flag is
unused, just ignore it silently.

For library functions, we only produce a warning. There is no way to

Artem Belevich f8144ab44f [CUDA] Improve CUDA compilation pipeline creation.
Current implementation tries to guess which Action will result in a
job which needs to incorporate device-side GPU binaries. The guessing
was attempting to work around the fact that multiple actions may be
combined into a single compiler invocation. If CudaHostAction ends up
being combined (and thus bypassed during action list traversal) no
device-side actions it pointed to were processed. The guessing worked
for most of the usual cases, but fell apart when external assembler
was used.

This change removes the guessing and makes sure we create and pass
device-side jobs regardless of how the jobs get combined.

* CudaHostAction is always inserted either at Compile phase or the
  FinalPhase of current compilation, whichever happens first.
* If selectToolForJob combines CudaHostAction with other actions, it
  passes info about CudaHostAction up to the caller
* When it sees that CudaHostAction got combined with other actions
  (and hence will never be passed to BuildJobsForActions),
  BuildJobsForActions creates device-side jobs the same way they would
  be created if CudaHostAction was passed to BuildJobsForActions
  directly.
* Added two more test cases to make sure GPU binaries are passed to
  correct jobs.

James Y Knight c4015d3291 Stop treating -static as overriding -fPIC: they are distinct.
For some reason, clang had been treating a command like:
 clang -static -fPIC foo.c
as if it should be compiled without the PIC relocation model.

This was incorrect: -static should be affecting only the linking
model, and -fPIC only the compilation.

This new behavior also matches GCC.

James Y Knight 5bdf7ab0cf Properly pass through the PIC mode to the integrated assembler when

On a few architectures, parsing of assembly files annoyingly depends
on whether PIC is enabled or not. This was handled for external 'as'
already (passing -KPIC), but was missed for calls to the standalone
internal assembler.

The integrated-as.s test needed to be modified to not expect
-fsanitize=address to be unused, as now fsanitize *IS* used for
assembly, since -fsanitize=memory can sometimes imply -fPIE, which the
assembler needs to know (gack!!).

Chandler Carruth 9ade6a9a74 Fix a tiny bug in -no-canonical-prefixes that somehow we have never
noticed until now.

The code for setting up the driver's InstalledDir didn't respect
-no-canonical-prefixes. Because of this, there are a few places in the
driver where we would unexpectedly form absolute paths, notably when
searching for and finding GCC installations to use, etc. The fix is
straightforward, and I've added this path to '-v' both so we can test it
sanely and so that it will be substantially more obvious the next time
someone has to debug something here.

Note that there is another bug that we don't actually *canonicalize* the
installed directory! I don't really want to fix that because I don't
have a realistic way to test the usage of this mode. I suspect that
folks using the shared module cache would care about getting this right
though, and so they might want to address it. I've left the appropriate
FIXMEs so that it is clear what to change, and I've updated the test
code to make it clear what is happening here.

Host-only cuda compilation does produce valid host object
file and in some cases users do want to proceed on to the linking phase.
The change removes special case that stopped compilation pipeline at
the Assembly phase. Device-side compilation is still stopped early
by the types::getCompilationPhases().

Renato Golin 7c542b4569 [ARM] Implement -Wa,-mfpu and friends for assemblers
This patch allows Clang to pass on -Wa,-mfpu, -Wa,-mhwdiv and
-Wa,-mcpu to the integrated assembler (via target-features), but
-march is still not being passed, but validated.

In case the command line has both -mxxx and -Wa,-mxxx, we warn
that the naked one will not be used in assembler mode.

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".

Currently, for --rtlib=compiler-rt on GNU systems, we're assuming

when used in conjunction with -lunwind or -lc++abi, breaks that
assumption.

My original fix was wrong, and this patch reverts it to prepare for
a new flag to choose the unwinder/C++ libraries. For the time being,
people can use "-lgcc_s -lgcc_eh" or "-lunwind -lc++abi" or any

Akira Hatanaka 0a23fac13c [ARM] Pass subtarget feature "+reserve-r9" instead of passing backend

This recommits r242736, which had to be reverted because the llvm-side
change that was committed in r242737 caused the number of subtarget
features to go over the limit of 64.

This change is needed since backend options do not make it to the backend
when doing LTO and are not capable of changing the behavior of code-gen
passes on a per-function basis.

Reid Kleckner e2d03448ba [clang-cl] Use the Windows response file tokenizer
We were still using the Unix response file tokenizer for all driver
modes. This was difficult to get right in the beginning because there is
a circular dependency. The Driver class also can't officially determine
its mode until it can see all possible --driver-mode= flags, and those
flags could come from the response file.

Now we use the Windows parsing algorithm if the program name looks like
clang-cl, or if the --driver-mode=cl flag is present on the main command
line.

Fixes PR23709.

Nevertheless, all tests requiring shell-preserves-root do pass except for
Driver/darwin-sdkroot.c. It will require a patch, either by disabling it on 
Windows or by fixing shell-preserves-root to really be true only on MSYS
and making darwin-sdkroot.c its only user.

In any case, all other tests requiring shell-preserves-root do not really require
it so I'm replacing REQUIRES: shell-preserves-root with REQUIRES: shell in two

NOTE: reverts r242077 to reinstate r242058, r242065, 242067

  - Added a test for cuda pipeline creation in clang driver.

  New clang options:
  --cuda-host-only   - Do host-side compilation only.
  --cuda-device-only - Do device-side compilation only.

  --cuda-gpu-arch=<ARCH> - specify GPU architecture for device-side
    compilation. E.g. sm_35, sm_30. Default is sm_20. May be used more
    than once in which case one device-compilation will be done per
