WebAssembly's spec has now been updated to specify some guarantees
about lock free atomic accesses. Update clang to match.
This also updates sig_atomic_t to be 64-bit on wasm64. WebAssembly
does not presently have asynchronous interrupts, but this change is
within the spirit of how they will work if they are added.

This makes int_fast64_t and int_least64_t the same type as int64_t, and
eliminates a difference between wasm32 and wasm64.

This is needed by all GlobalObjects (GlobalAlias, Function,
GlobalVariable), see the GlobalObject::getValueType which is used in
many places. If at some point that can be removed, then we can remove
this member.

MS compiler ignores calling convention modifiers for structors. This patch makes
clang do the same (for MS ABI). This fixes PR24595 and makes vswriter.h header
(from Windows SDK 8.1) compilable.

There are situations where a user may want to build only the compiler-rt builtins, or only the sanitizer runtimes. This exposes options to do that. Both default to On, so there should be no implicit change in behavior.

Targets that have non-traditional jump table mechanisms may need to do
something substantially different for jump tables than what
AsmPrinter::EmitJumpTableInfo does. This patch makes that function
virtual so that targets can override it.

This is actually needed, otherwise libc won't be added at all. For
instance when building libclang.so all the libc symbols won't be
found, with ld warning about libc being an "implicit dependency".

TestPersistObjCPointeeType and TestObjCNewSyntax marked up to expect
success on clang >= 7.0.0.
TestMultipleDebuggers passed 25/25 times, taking off intermittent.
If this changes, I'll make sure it goes into a flaky/flakey category.

Add polly-check-format as dependency of check-polly if clang-format is

These are a few cleanups I happened to have from trying to go in a
different direction recently, so just flushing them out while I have
them.

This is required because ExternalProject_Add requires all targets specified in the DEPENDS argument must exist before calling ExternalProject_Add.

- There are no duplicate registers in LiveRegs list we are copying from
and so we do not need to sort the registers.
- Simply use SmallVector::apend instead of a loop between begin() and end()
with push_back().

Summary: This patch replaces isKnownNonNull() with isKnownNonNullAt() when checking nullness of passing arguments at callsite. In this way it can handle cases where the argument does not have nonnull attribute but has a dominating null check from the CFG. It also adds assertions in isKnownNonNull() and isKnownNonNullFromDominatingCondition() to make sure the value checked is pointer type (as defined in LLVM document). These assertions might trip failures in things which are not covered under llvm/test, but fixes should be pretty obvious.

This was the wrong direction to take anyway (because ultimately the
GlobalValue needed the pointee type again and /it/ used
PointerType::getElementType eventually anyway)... let's go a different way.
This reverts commit r236161.
llvm-svn: 247586
This was a flawed change - it just caused the getElementType call to be
deferred until later, when we really need to remove it. Now that the IR
for GlobalAliases has been updated, the root cause is addressed that way
instead and this change is no longer needed (and in fact gets in the way
- because we want to pass the pointee type directly down further).
Follow up patches to push this through GlobalValue, bitcode format, etc,
will come along soon.
This reverts commit 236160.

This change deletes the Makefile+Perl build system and all files used by it
which aren't used by the CMake build system. This included many Perl files,
*.mk files, iomp* files. This change also updates the README's and
index.html to instruct the user to use the CMake build system. All mentioning
of the Perl+Makefile based system are removed.

This is a follow up to r247518.
As a general note, I think we could do a much better job testing for
error conditions in tools. I already anticipated in a previous mail,
but while implementing this I noticed that the code coverage we have
for error checking is pretty low. I can arbitrarily remove checks from
several tools and the suite still passes.

Summary:
Make clang-format run on each file independently using
add_custom_format (instead using a shell script in utils/). The targets
polly-{update|check}-format depend on these.
The primary motivation is to make them work on Windows, but also
improves them generally:
- Each file update/check can run in parallel (Although they do not take
long to run anyway)
- Implicit dependency on clang-format, so it recompiles if necessary
- polly-check-format shows the formatting difference if failing
