Summary:
I needed to know whether a FieldDecl had an in-class
initializer for D26453. I used a narrowing matcher there, but a
traversal matcher might be generally useful.

This AST matcher will match a given CastExpr kind.
It's an narrowing matcher on CastExpr.

Summary: Matcher proposed in the review of checker misc-assign-operator (name pending). Its goal is to find the direct enclosing function declaration of a statement and run the inner matcher on it. Two version is attached in this patch (thus it will not compile), to be decided which approach to take. The second one always chooses one single parent while the first one does a depth-first search upwards (thus a height-first search) and returns the first positive match of the inner matcher (thus it always returns zero or one matches, not more). Further questions: is it enough to implement it in-place, or ASTMatchersInternals or maybe ASTMatchFinder should be involved?

Summary:
llvm::VariadicFunction is only being used by ASTMatchers.
Having our own copy here allows us to remove the other one from llvm/ADT.
Also, we can extend the API to meet our needs without modifying the common
implementation.

Summary: A checker (will be uploaded after this patch) needs to check implicit casts. Existing generic matcher "has" ignores implicit casts and parenthesized expressions and no specific matcher for matching return value expression preexisted. The patch adds such a matcher (hasReturnValue).

This is the third time it has crossed the 2^16 section limit. We've
already spent time optimizing this file to reduce template
instantiations, and it's not clear that there is anymore low hanging
fruit.

The new matcher allows users to provide a matcher for both the argument
of a CallExpr/CxxConstructExpr a well as the ParmVarDecl of the
argument.

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.
llvm-svn: 247404
Individual matchers might not be convertible to each other's kind, but
they might still all be convertible to the target kind.
All the callers already know the target kind, so just pass it down.

It's better not to rely on the diagnostics engine to pretty print the
argument to decltype. Instead, exercise the functionality in
DeclPrinterTest.

If the type isn't trivially moveable emplace can skip a potentially
expensive move. It also saves a couple of characters.
Call sites were found with the ASTMatcher + some semi-automated cleanup.
memberCallExpr(
argumentCountIs(1), callee(methodDecl(hasName("push_back"))),
on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))),
hasArgument(0, bindTemporaryExpr(
hasType(recordDecl(hasNonTrivialDestructor())),
has(constructExpr()))),
unless(isInTemplateInstantiation()))
No functional change intended.

Add some matchers for Objective-C selectors and messages to

Change to original: ifndef out tests in Windows due to /-separated
paths.
Summary:
Often one is only interested in matches within the main-file or matches
that are not within a system-header, for which this patch adds
isInMainFile and isInSystemFile. They take no arguments and narrow down
the matches.
The isInFileMatchingName is mainly thought for interactive
clang-query-sessions, to make a matcher more specific without restarting
the session with the files you are interested in for that moment. It
takes a string that will be used as regular-expression to match the
filename of where the matched node is expanded.

Summary:
Replace variadic operator function pointer with an enum value.
Hiding the implementation of the variadic matcher will allow to specialize them for the operation performed.
In particular, it will allow for a more efficient allOf() matcher.

Summary:
The generic variadic matcher is faster (one less virtual function call
per match) and doesn't require template instantiations which reduces
compile time and binary size.
Registry.cpp.o generates ~14% less symbols and compiles ~7.5% faster.
The change also speeds up our clang-tidy benchmark by ~2%.

Summary:
There was an assumption that there were no matchers that were overloaded
on matchers and other types of arguments.
This assumption was broken recently with the addition of new matcher
overloads.

Summary:
Refactor VariantMatcher::MatcherOps to reduce the amount of generated code.
- Make some code type agnostic and move it to the cpp file.
- Return a DynTypedMatcher instead of storing the object in MatcherOps.
This change reduces the number of symbols generated in Registry.cpp by
~19%, the object byte size by ~17% and the compilation time (in non-release mode) by ~20%.
