Gabor Horvath 1b3f8db8b6 [ASTMatchers] New matcher forFunction
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: 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).

Summary:
Allow hasName() to look through inline namespaces.
This will fix the interaction between some clang-tidy checks and libc++.

libc++ defines names in an inline namespace named std::<version_#>.
When we try to match a name using hasName("std::xxx") it fails to match and the clang-tidy check does not work.

Richard Smith 8583872060 Use data recursion in RecursiveASTVisitor when traversing Stmt and Expr nodes.
When RAV traverses a Stmt or Expr node, if the corresponding Traverse*
functions have not been overridden, it will now use data recursion to walk
those nodes. We arrange this to be an unobservable optimization to RAV
subclasses, and to gracefully degrade as parts of the visitation are overridden
with functions that might observe the visitation.

For instance, if an RAV subclass overrides TraverseUnaryNot, we will ensure
that there are real recursive stack frames for those traversals, but we'll
use data recursion for all other traversals.

This removes the need for DataRecursiveASTVisitor, and for the
'shouldUseDataRecursionFor' extension point, both of which are removed by this
change.

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 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.
