Two new matchers for `CXXNewExpr` are added which may be useful e.g. in
`clang-tidy` checkers. One of them is `isArray` which matches `new[]` but not
plain `new`. The other one, `hasArraySize` matches `new[]` for a given size.
llvm-svn: 318909
Summary:
Allow the `isDefinition()` matcher to apply to `ObjCMethodDecl` nodes, in
addition to those it already supports. For whatever reason, `ObjCMethodDecl`
does not inherit from `FunctionDecl` and so this is specialization is necessary.

The wording in the documentation for the matcher isExternC
appears to be misleading since this matcher
is applicable to functions and variables as well.

Originally, we weren't able to match on Type nodes themselves (only QualType),
so the hasDeclaration matcher was initially written to give what we thought are
reasonable results for QualType matches.
When we chagned the matchers to allow matching on Type nodes, it turned out
that the hasDeclaration matcher was by chance written templated enough to now
allow hasDeclaration to also match on (some) Type nodes.
This patch change the hasDeclaration matcher to:
a) work the same on Type and QualType nodes,
b) be completely explicit about what nodes we can match instead of just allowing
anything with a getDecl() to match,
c) explicitly control desugaring only one level in very specific instances.
d) adds hasSpecializedTemplate and tagType matchers to allow migrating
existing use cases that now need more explicit matchers
Note: This patch breaks clang-tools-extra. The corresponding patch there
is approved and will land in a subsequent patch.

Trying to match integerLiteral(-1) will silently fail, because an numeric
literal is always positive.
- Update the documentation to explain how to match negative numeric
literals.
- Add a unit test.

Summary:
This allows the clang-query tool to use matchers like
"integerLiteral(equals(32))". For this to work, an overloaded function
is added for each possible parameter type.

Summary:
This adds a new ASTMatcher for CXXStdInitializerListExprs that matches C++ initializer list expressions.
The primary motivation is to use it to fix [[ https://bugs.llvm.org/show_bug.cgi?id=32896 | PR32896 ]] (review here [[ https://reviews.llvm.org/D32767 | D32767 ]]).

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.

The change from llvm::VariadicFunction to internal::VariadicFunction
broke the extraction of hasAnyName().
equalsNode was broken because the argument type is 'const XXXX*' and
the internal space caused a failure on the regex.
llvm-svn: 268548
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?
