Arpith Chacko Jacob fe4890a68b [OpenMP] Support for the if-clause on the combined directive 'target parallel'.
The if-clause on the combined directive potentially applies to both the
'target' and the 'parallel' regions.  Codegen'ing the if-clause on the
combined directive requires additional support because the expression in
the clause must be captured by the 'target' capture statement but not
the 'parallel' capture statement.  Note that this situation arises for
other clauses such as num_threads.

The OMPIfClause class inherits OMPClauseWithPreInit to support capturing
of expressions in the clause.  A member CaptureRegion is added to
OMPClauseWithPreInit to indicate which captured statement (in this case
'target' but not 'parallel') captures these expressions.

To ensure correct codegen of captured expressions in the presence of
combined 'target' directives, OMPParallelScope was added to 'parallel'
codegen.

Aleksey Shlypanikov pointed out my mistake in migrating an explicit

Sean Callanan 7d982509b8 Testbed and skeleton of a new expression parser
Recommitted after formal approval.

LLVM's JIT is now the foundation of dynamic-compilation features for many languages. Clang also has low-level support for dynamic compilation (ASTImporter and ExternalASTSource, notably). How the compiler is set up for dynamic parsing is generally left up to individual clients, for example LLDB's C/C++/Objective-C expression parser and the ROOT project.

Although this arrangement offers external clients the flexibility to implement dynamic features as they see fit, the lack of an in-tree client means that subtle bugs can be introduced that cause regressions in the external clients but aren't caught by tests (or users) until much later. LLDB for example regularly encounters complicated ODR violation scenarios where it is not immediately clear who is at fault.

Other external clients (notably, Cling) rely on similar functionality, and another goal is to break this functionality up into composable parts so that any client can be built easily on top of Clang without requiring extensive additional code.

I propose that the parts required to build a simple expression parser be added to Clang. Initially, I aim to have the following features:

A piece that looks up external declarations from a variety of sources (e.g., from previous dynamic compilations, from modules, or from DWARF) and uses clear conflict resolution rules to reconcile differences, with easily understood errors. This functionality will be supported by in-tree tests.
A piece that works hand in hand with the LLVM JIT to resolve the locations of external declarations so that e.g. variables can be redeclared and (for high-performance applications like DTrace) external variables can be accessed directly from the registers where they reside.
This commit adds a tester that parses a sequence of source files and then uses them as source data for an expression. External references are resolved using an ExternalASTSource that responds to name queries using an ASTImporter. This is the setup that LLDB uses, and the motivating reason for MinimalImport in ASTImporter. When complete, this tester will implement the first of the above goals.

Richard Smith 151c456858 [c++1z] P0195R2: Support pack-expansion of using-declarations.
This change introduces UsingPackDecl as a marker for the set of UsingDecls
produced by pack expansion of a single (unresolved) using declaration. This is
not strictly necessary (we just need to be able to map from the original using
declaration to its expansions somehow), but it's useful to maintain the
invariant that each declaration reference instantiates to refer to one
declaration.

This is a re-commit of r290080 (reverted in r290092) with a fix for a
use-after-lifetime bug.

Summary:
Fixes spelling name ranges for user-defined string literal operators.

Example:
  constexpr int operator""_toint(unsigned long long val)
  { return int(val); }

Before this patch the spelling name range on consisted of 'operator'.

After this patch: 'operator""_toint'.

Related to http://reviews.llvm.org/D5041, which fixes the function for
other cursor kinds.

  Cannot export clang_findIncludesInFileWithBlock: symbol not defined
  Cannot export clang_findReferencesInFileWithBlock: symbol not defined
  Cannot export clang_visitChildrenWithBlock: symbol not defined

They are excluded conditionally in header along has_blocks.

We should do either;

  1. Exclude also function bodies conditionally, and introduce "optional" exporter.
  2. Give dummy function bodies for them.
  3. Implement functions w/o blocks.

Antonio Maiorano 5ccb65f77d clang-format-vsix: add a date stamp to the VSIX version number to ensure upgradability
Presently, the version number of the VSIX matches the LLVM version number. However, as this number doesn't change often, it means that as we release new versions of this VSIX, it will have the same version number, which means users must first uninstall the old version before installing the new one. With this change, we generate a 4th part to the version number that is a date stamp (year, month, day); for example: 4.0.0.161203.

Daniel Jasper 03a04fe95f clang-format: Separate out a language kind for ObjC.
While C(++) and ObjC are generally formatted the same way and can be
mixed, people might want to choose different styles based on the
language. This patch recognizes .m and .mm files as ObjC and also
implements a very crude detection of whether or not a .h file contains
ObjC code. This can be improved over time.

Also move most of the ObjC tests into their own test file to keep file
size maintainable.

Richard Smith 410306bf6e Add two new AST nodes to represent initialization of an array in terms of
initialization of each array element:

 * ArrayInitLoopExpr is a prvalue of array type with two subexpressions:
   a common expression (an OpaqueValueExpr) that represents the up-front
   computation of the source of the initialization, and a subexpression
   representing a per-element initializer
 * ArrayInitIndexExpr is a prvalue of type size_t representing the current
   position in the loop

This will be used to replace the creation of explicit index variables in lambda
capture of arrays and copy/move construction of classes with array elements,
and also C++17 structured bindings of arrays by value (which inexplicably allow
copying an array by value, unlike all of C++'s other array declarations).

No uses of these nodes are introduced by this change, however.
