This reverts commit r211096. Looks like it broke the msvc build:
SemaOpenMP.cpp(140) : error C4519: default template arguments are only allowed on a class template

By describing system header suppressions directly in tablegen we eliminate
special cases in getDiagnosticSeverity().
Dropping the reliance on builtin diagnostic classes when mapping also gets us
closer to the goal of reusing the diagnostic machinery for custom diagnostics.
No change in functionality.

This improves conformance with ACLE 6.4.1. Define additional macros that
indicate support for the ARM and Thumb instruction set architecture. This
includes the following set of macros:
__ARM_ARCH
__ARM_ARCH_ISA_ARM
__ARM_ARCH_ISA_THUMB
__ARM_32BIT_STATE
These help identify the environment that the code is intended to execute on.
Adjust the handling for ACLE 6.4.2 to be more correct. We would define the
profile as a free-standing token rather than a quoted single character.

Thanks to David Blakie and Richard Smith for pointing out that we can retain the
-Wswitch coverage while avoiding the warning from GCC by pushing the unreachable
outside of the switch!

This begins to address cognitive dissonance caused by treating the Note
diagnostic level as a severity in the diagnostic engine.

For ARM target, we can use CRYPTO and CRC features if we select
cortex-a57 by '-mcpu', but for AArch64 target, it doesn't work
unless adding with '-mfpu=crypto-neon-fp-armv8'. To keep consistency
between front-end and back-end and get end-users more easier to use,
we'd better add default feature for CPUs on AArch64 target as well.

Diagnostic mappings are used to calculate the final severity of diagnostic
instances.
Detangle the implementation to reflect the terminology used in documentation
and bindings.
No change in functionality.

Anyone enabling this warning would expect to hear about all occurrences
including those in system headers that can cause non-reproducible builds.
To achieve this, rework ShowInSystemHeader to remove broken unused mapping code
that didn't make sense with a simpler and correct scheme.

We probably just need to touch LLVM's configure this time to work around the
totally inadequate Makefile build server integration.
This reverts commit r210314.
llvm-svn: 210320
This will unbreak clang vendor builds as a follow-up to r210238, now that we
can't poke into LLVM's private config.h (nor should the string be exposed by
llvm-config.h).
This hopefully removes for good the last include of LLVM's config.h.

Summary: The Linux Kernel is one example of a piece of software that relies on them.

This corrects long-standing misuses of LLVM's internal config.h.
In most cases the public llvm-config.h header was intended and we can now
remove the old hacks thanks to LLVM r210144.
The config.h header is private, won't be installed and should no longer be
included by clang or other modules.
llvm-svn: 210145
There shouldn't be any difference in behaviour here, at least not in
any configurations people care about and possibly not in any reachable
configurations.

A few (mostly CodeGen) parts of Clang were tightly coupled to the
AArch64 backend. Now that it's gone, they will not even compile.
I've also deduplicated RUN lines in many of the AArch64 tests. This
might improve "make check-all" time noticably: some of those NEON
tests were monsters.

If we lookup a path using its 'real' path first, we need to ensure that
when we run header search we still use the VFS-mapped path or we will
not be able to find the corresponding module for the header.
The real problem is that we tie the name of a file to its underlying
FileEntry, which is uniqued by inode, so we only ever get the first name
it is looked up by. This doesn't work with modules, which rely on a
specific file system structure. I'm hoping to have time to write up a
proposal for fixing this more permanently soon, but as a stopgap this
patch updates the name of the file's directory if it comes from a VFS
mapping.
llvm-svn: 209534
Summary:
The limits on the number of fix-it hints and ranges attached to a
diagnostic are arbitrary and don't apply universally to all users of the
DiagnosticsEngine. The way the limits are enforced may lead to diagnostics
generating invalid sets of fixes. I suggest removing the limits, which will also
simplify the implementation.

There are a couple of issues with writing VFS maps that are awkward to
fix within the current mutually recursive approach. Instead, replace
the algorithm with an iterative version that uses an explicit stack of
directories.
Includes tests for cases the old approach was tripping on.

Checking if a path starts with another path isn't sufficient for
determining if one is contained within the heirarchy of the other.
We need to ensure that the substring ends at a directory boundary.

This moves the logic to write a JSON VFS mapping from the C api into
VirtualFileSystem, so that we can use it internally.
No functional change.
