Summary:
It was used for interoperability with PNaCl's calling conventions, but
it's no longer needed.
Also Remove NaCl*ABIInfo which just existed to delegate to either the portable
or native ABIInfo, and remove checkCallingConvention which was now a no-op
override.

The test was fixed after a discussion with the revision author: the check
pattern was made more flexible as the "%call" part is not what we actually want
to check strictly there.
The original patch description:
===
Introduce SPIR calling conventions.
This implements Section 3.7 from the SPIR 1.2 spec:
SPIR kernels should use "spir_kernel" calling convention.
Non-kernel functions use "spir_func" calling convention. All
other calling conventions are disallowed.
The patch works only for OpenCL source. Any other uses will need
to ensure that kernels are assigned the spir_kernel calling
convention correctly.

Sorry for the noise, I managed to miss a bunch of recent regressions of
include orderings here. This should actually sort all the includes for
Clang. Again, no functionality changed, this is just a mechanical
cleanup that I try to run periodically to keep the #include lines as
regular as possible across the project.

I'm not sure why we have OS.indent(Indent+2) for the system attribute,
but presumably we want the same behaviour for all attributes...

even though every basic source character literal has the same numerical value
as a narrow or wide character literal.
It appears that the FreeBSD folks are trying to use this macro to mean
something other than what the relevant standards say it means, but their usage
is conforming, so put up with it.

Clang would treat the digits in an "11m" input constraint separately as
if it was handling constraint 1 twice instead of constraint 11.
llvm-svn: 225606
Input constraints like "0" and "[foo]" should be treated the same when
it comes to their corresponding output constraint.
This fixes PR21850.

Add additional constraint checking for target specific behaviour for inline
assembly constraints. We would previously silently let all arguments through
for these constraints. In cases where the constraints were violated, we could
end up failing to select instructions and triggering assertions or worse,
silently ignoring instructions.

use clang -cc1 matching the front end and backend. Fix up a couple
of tests that were testing aapcs for arm-linux-gnu.
The test that removes the aapcs abi calling convention removes
them because the default triple matches what the backend uses
for the calling convention there and so it doesn't need to be
explicitly stated - see the code in TargetInfo.cpp.

Add a comment and a test to ~DiagnosticEngine about the ordering
requirements on the teardown of DiagnosticConsumer. This could also be
accomplished by rearranging the fields of ~DiagnosticEngine, but I felt
that this was a better, more explicit solution.
This fixes PR21911, an issue that occurred after the unique_ptr
migration in r222193.

Summary:
Because GCC doesn't use $1 for code generation, inline assembly code can use $1 without having to add it to the clobbers list.
LLVM, on the other hand, does not shy away from using $1, and this can cause conflicts with inline assembly which assumes GCC-like code generation.
A solution to this problem is to make Clang automatically clobber $1 for all MIPS inline assembly.
This is not the optimal solution, but it seems like a necessary compromise, for now.

This way, the step generating SVNVersion.inc gets rerun every time someone
changes GetSVN.cmake (which is the file that decides how the contents of
SVNVersion.inc look). This makes hacking on GetSVN.cmake a bit easier.

basic microarchitecture names, and add support (with tests) for parsing
all of the masic microarchitecture names for CPUs documented to be
accepted by GCC with -march. I didn't go back through the 32-bit-only
old microarchitectures, but this at least brings the recent architecture
names up to speed. This is essentially the follow-up to the LLVM commit
r223769 which did similar cleanups for the LLVM CPUs.
One particular benefit is that you can now use -march=westmere in Clang
and get the LLVM westmere processor which is a different ISA variant (!)
and so quite significant.
Much like with r223769, I would appreciate the Intel folks carefully
thinking about the macros defined, names used, etc for the atom chips
and newest primary x86 chips. The current patterns seem quite strange to
me, especially here in Clang.
Note that I haven't replicated the per-microarchitecture macro defines
provided by GCC. I'm really opposed to source code using these rather
than using ISA feature macros.

aapcs on armv7-ios when the actual ABI is apcs.
Should be no user visible change without -cc1.

Summary:
Allow CUDA host device functions with two code paths using __CUDA_ARCH__
to differentiate between code path being compiled.
For example:
__host__ __device__ void host_device_function(void) {
#ifdef __CUDA_ARCH__
device_only_function();
#else
host_only_function();
#endif
}

Summary:
This change implements warnings if macro name is identical to a keyword or
reserved identifier. The warnings are different depending on the "danger"
of the operation. Defining macro that replaces a keyword is on by default.
Other cases produce warning that is off by default but can be turned on
using option -Wreserved-id-macro.
This change fixes PR11488.

rather than trying to extract this information from the FileEntry after the
fact.
This has a number of beneficial effects. For instance, diagnostic messages for
failed module builds give a path relative to the "module root" rather than an
absolute file path, and the contents of the module includes file is no longer
dependent on what files the including TU happened to inspect prior to
triggering the module build.

To support it in the frontend, the following has been added:

- documentation for the OpenCL address space attributes;
- parsing of __generic(generic) keyword;
- test code for the parser and diagnostics.

In order to keep SVNVersion.inc from being regenerated on every build, we need
to specify as a dependency a file that only changes when the VC state updates.
I previously just had .svn/entries, but that's only used by Subversion 1.6.
1.7 uses .svn/wc.db instead; prefer that if it's present.
(Thanks, Nico!)

Now that LLVM's helper script GetSVN.cmake actually works consistently,
there's no reason not to use it. We avoid having to regenerate SVNVersion.inc
every time by marking it as dependent on Git's reflog or SVN's entries file.
This should end most of the issues of the AST format changing and breaking
old module files: CMake-Clang should now detect that the version changed just
like Autoconf-Clang has.
Based on r190557. Depends on LLVM r222391.
