Weak symbols cannot use the small code model's usual ADRP sequences since the
instruction simply may not be able to encode a value of 0.

This redirects them to use the GOT, which hopefully linkers are able to cope
with even in the static relocation model.

We were creating libcall nodes that returned an MVT::f128, when these
particular operations actually return an int of some stripe.

llvm-svn: 205425

Some Intrinsics are overloaded to the extent that return type equality (all
that's been checked up to now) does not guarantee that the arguments are the
same. In these cases SLP vectorizer should not recurse into the operands, which
can be achieved by comparing them as "Function *" rather than simply the ID.

Again, coalescing and other optimisations swiftly made the MachineInstrs
consistent again, but when compiled at -O0 a bad INSERT_SUBREGISTER was
produced.

llvm-svn: 205423

The previous attempt was fine with optimisations, but was actually rather
cavalier with its types. When compiled at -O0, it produced invalid COPY
MachineInstrs.

Summary:
Add support for named values in the parser.
This allows injection of arbitrary constants using a custom Sema object.
Completions are not supported right now.

Will be used by clang_query to support the 'let' command.
Usage example:
  clang_query> let unique_ptr recordDecl(hasName("unique_ptr"))
  clang_query> match varDecl(hasType(unique_ptr))

It does not do what it's name says, and what it actually does is hard to
describe, and is not useful at all.

This replaces the ancient INVALID/INVALID_NOVERIFY macros with a real
function.

The new invalid(..) function uses small diagnostic objects that are
generated on demand. We can store arbitrary additional information per
error type and generate useful debug/error messages on the fly.

Use it as follows:
  if (/* Some error condition (ReportFoo) */)
    invalid<ReportFoo>(Context, /*Assert=*/true/false,
      (/* List of helpful diagnostic objects */));

Where ReportFoo is a subclass of RejectReason that is able to take the
list of helpful diagnostic objects in its constructor.
The implementation of invalid will create the report and fire
an assertion, if necessary.

Also make tests slightly less dependent on default flags. Once we have
implemented configuration file support, we might want to store the
clang-tidy configuration for the tests there.

llvm-svn: 205408

The goal is to be able to run clang-tidy on LLVM files without further
configuration for now. Once llvm.org/PR19306 is addressed, we can add a
configuration file instead and choose other defaults.

No one inherits Resolver. Virtualizing the member functions was just
making it inefficient.

For namespaces, this is consistent with mangling and GCC's debug info
behavior. For structs, GCC uses <anonymous struct> but we prefer
consistency between all anonymous entities but don't want to confuse
them with template arguments, etc, so we'll just go with parens in all
cases.

While investigating some debug info issues, Eric and I came across a
particular template case where the location of a decl was quite
different from the range of the same decl. It might've been rather
helpful if the dumper had actually showed us this.

LinkingContext and InputGraph are unnecessarily entangled. Most linker
input file data, e.g. the vector containing input files, the next index
of the input file, etc. are managed by InputGraph, but only the current
input file is for no obvious reason managed by LinkingContext.

This patch is to move code from LinkingContext to InputGraph to fix it.
It's now clear who's reponsible for managing input file state, which is
InputGraph, and LinkingContext is now free from that responsibility.
It improves the readability as we now have fewer dependencies between
classes. No functionality change.

This is a mechanical change addressing the various sign comparison warnings that
are identified by both clang and gcc.  This helps cleanup some of the warning
spew that occurs during builds.
