Daniel Jasper f67c32466d clang-format: Be slightly more cautious when formatting subsequent lines after a change. With r251474, clang-format could indent the entire rest of the file, if there is a missing closing brace, e.g. while writing code in an editor.
Summary:
With this change, clang-format stops formatting when either it leaves
the current scope or when it comes back to the initial scope after
going into a nested one.

Samuel Antao 4c1f1c33b1 Minor fix in ToolChainTest.cpp to allow user defined GCC toolchain.

Summary:
If this option is set, clang-format will always insert a line wrap, e.g.
before the first parameter of a function call unless all parameters fit
on the same line. This obviates the need to make a decision on the
alignment itself.

Use this style for Google's JavaScript style and add some minor tweaks
to correctly handle nested blocks etc. with it. Don't use this option
for for/while loops.

Benjamin Kramer 94355aeff8 [AST] Re-add TypeLocs and NestedNameSpecifierLocs to the ParentMap.
This relands r250831 after some fixes to shrink the ParentMap overall
with one addtional tweak: nodes with pointer identity (e.g. Decl* and
friends) can be store more efficiently so I put them in a separate map.
All other nodes (so far only TypeLoc and NNSLoc) go in a different map
keyed on DynTypedNode. This further uglifies the code but significantly
reduces memory overhead.

Overall this change still make ParentMap significantly larger but it's
nowhere as bad as before. I see about 25 MB over baseline (pre-r251008)
on X86ISelLowering.cpp. If this becomes an issue we could consider
splitting the maps further as DynTypedNode is still larger (32 bytes)
than a single TypeLoc (16 bytes) but I didn't want to introduce even
more complexity now.

Benjamin Kramer 9bccaa158a [Tooling] Add a utility function to replace one nested name with another.
One problem in clang-tidy and other clang tools face is that there is no
way to lookup an arbitrary name in the AST, that's buried deep inside Sema
and might not even be what the user wants as the new name may be freshly
inserted and not available in the AST.

A common use case for lookups is replacing one nested name with another
while minimizing namespace qualifications, so replacing 'ns::foo' with
'ns::bar' will use just 'bar' if we happen to be inside the namespace 'ns'.
This adds a little helper utility for exactly that use case.

Benjamin Kramer 998039e2f6 Shrink DynTypedNode by one pointer from 40 to 32 bytes (on x86_64).
The MemoizationData cache was introduced to avoid a series of enum
compares at the cost of making DynTypedNode bigger. This change reverts
to using an enum compare but instead of building a chain of comparison
the enum values are reordered so the check can be performed with a
simple greater than. The alternative would be to steal a bit from the
enum but I think that's a more complex solution and not really needed
here.

I tried this on several large .cpp files with clang-tidy and didn't
notice any performance difference. The test change is due to matchers
being sorted by their node kind.

Benjamin Kramer e8c51fdbd6 Revert "[AST] Put TypeLocs and NestedNameSpecifierLocs into the ParentMap."
Putting DynTypedNode in the ParentMap bloats its memory foot print.
Before the void* key had 8 bytes, now we're at 40 bytes per key which
can mean multiple gigabytes increase for large ASTs and this count
doesn't even include all the added TypeLoc nodes. Revert until I come
up with a better data structure.

This reverts commit r250831.

Benjamin Kramer 36307ffa1b [AST] Put TypeLocs and NestedNameSpecifierLocs into the ParentMap.
Firstly this changes the type of parent map to be keyed on DynTypedNode to
simplify the following changes. This comes with a DenseMapInfo for
DynTypedNode, which is a bit incomplete still and will probably only work
for parentmap right now.

Then the RecursiveASTVisitor in ASTContext is updated and finally
ASTMatchers hasParent and hasAncestor learn about the new functionality.

Now ParentMap is only missing TemplateArgumentLocs and CXXCtorInitializers.

Daniel Jasper 265309e38a clang-format: [JS] Handle string literals spanning character classes.
If a RegExp contains a character group with a quote (/["]/), the
trailing end of it is first tokenized as a string literal, which leads
to the merging code seeing an unbalanced bracket.

This change parses regex literals from the left hand side. That
simplifies the parsing code and also allows correctly handling escapes
and character classes, hopefully correctly parsing all regex literals.

This is useful for debugging of issues and reduction of test cases.
For example, an issue may show up due to the order that some commands were processed.
It is convenient to be able to remove commands from the file and still preserve the order
that they are returned, instead of getting a completely different order when removing a few commands.

Aaron Ballman b85be665b0 Fixed HasDeclarationMatcher to properly convert all types into decls where possible. Added objcObjectPointerType(), objcInterfaceDecl(), templateTypeParmType(), injectedClassNameType(), and unresolvedUsingTypenameDecl(). Updated documentation for pointerType() to call out that it does not match ObjCObjectPointerType types. Changed pointsTo() to handle ObjCObjectPointerType as well as PointerType.
While this may seem like a lot of unrelated changes, they all relate back to fixing HasDeclarationMatcher.

This now allows us to write a matcher like:

varDecl(hasType(namedDecl(hasName("Foo"))))

that matches code using typedefs, objc interfaces, template type parameters, injected class names, or unresolved using typenames.

Daniel Jasper 100ffc632a clang-format: Be more conservative about specially indenting blocks in C++.
This is a bit of a step back of what we did in r222531, as there are
some corner cases in C++, where this kind of formatting is really bad.

Example:
Before:
  virtual aaaaaaaaaaaaaaaa(std::function<bool()> IsKindWeWant = [&]() {
    return true;
  }, aaaaa aaaaaaaaa);

After:
  virtual aaaaaaaaaaaaaaaa(std::function<bool()> IsKindWeWant =
                               [&]() { return true; },
                           aaaaa aaaaaaaaa);

The block formatting logic in JavaScript will probably go some other changes,
too, and we'll potentially be able to make the rules more consistent again. For
now, this seems to be the best approach for C++.

Manuel Klimek 54042e743c Add structed way to express command line options in the compilation database.
Currently, arguments are passed via the string attribute 'command',
assuming a shell-escaped / quoted command line to extract the original
arguments. This works well enough on Unix systems, but turns out to be
problematic for Windows tools to generate.

This CL adds a new attribute 'arguments', an array of strings, which
specifies the exact command line arguments. If 'arguments' is available
in the compilation database, it is preferred to 'commands'.

Currently there is no plan to retire 'commands': there are enough
different use cases where users want to create their own mechanism for
creating compilation databases, that it doesn't make sense to force them
all to implement shell command line parsing.

  - Added a test for cuda pipeline creation in clang driver.

  New clang options:
  --cuda-host-only   - Do host-side compilation only.
  --cuda-device-only - Do device-side compilation only.

  --cuda-gpu-arch=<ARCH> - specify GPU architecture for device-side
    compilation. E.g. sm_35, sm_30. Default is sm_20. May be used more
    than once in which case one device-compilation will be done per

Birunthan Mohanathas b001a0ba5e clang-format: Add MacroBlock{Begin,End} options
The MacroBlockBegin and MacroBlockEnd options make matching macro identifiers
behave like '{' and '}', respectively, in terms of indentation.

Mozilla code, for example, uses several macros that begin and end a scope.
Previously, Clang-Format removed the indentation resulting in:

    MACRO_BEGIN(...)
    MACRO_ENTRY(...)
    MACRO_ENTRY(...)
    MACRO_END

Now, using the options

    MacroBlockBegin: "^[A-Z_]+_BEGIN$"
    MacroBlockEnd: "^[A-Z_]+_END$"

will yield the expected result:

    MACRO_BEGIN(...)
      MACRO_ENTRY(...)
      MACRO_ENTRY(...)
    MACRO_END

Adrian Prantl bb165fb04d Introduce a PCHContainerOperations interface (NFC).
A PCHContainerOperations abstract interface provides operations for
creating and unwrapping containers for serialized ASTs (precompiled
headers and clang modules). The default implementation is
RawPCHContainerOperations, which uses a flat file for the output.

The main application for this interface will be an
ObjectFilePCHContainerOperations implementation that uses LLVM to
wrap the module in an ELF/Mach-O/COFF container to store debug info
alongside the AST.

This is still bad, but at least it is consistent with what we do for other
function literals. Added corresponding tests.

Daniel Jasper f841d3a6c1 clang-format: Lower binding strengths created by the [] created by ObjC
method expressions and array literals. They should not bind stronger
than regular parentheses or the braces of braced lists.

Specific test case in JavaScript:
Before:
  var aaaaa: List<
      SomeThing> = [new SomeThingAAAAAAAAAAAA(), new SomeThingBBBBBBBBB()];

After:
  var aaaaa: List<SomeThing> = [
    new SomeThingAAAAAAAAAAAA(),
    new SomeThingBBBBBBBBB()
  ];

Daniel Jasper 0843434e74 clang-format: Guard the bin-packing in braced lists on BinPackArguments
instead of BinPackParameters. Braced lists are used as constructor
calls in many places and so the bin-packing should follow what is done
for other calls and not what is done for function declarations.
