2012-03-08Add a basic CallGraph to Analysis.Anna Zaks
The final graph contains a single root node, which is a parent of all externally available functions(and 'main'). As well as a list of Parentless/Unreachable functions, which are either truly unreachable or are unreachable due to our analyses imprecision. The analyzer checkers debug.DumpCallGraph or debug.ViewGraph can be used to look at the produced graph. Currently, the graph is not very precise, for example, it entirely skips edges resulted from ObjC method calls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152272 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-07Workaround module test failures by removing the version info from module hashes.Bob Wilson
PR12196: The module hash strings are not actually hashing the compiler version string; the entire version string is being included in the hash. Depending on the module cache directory name, that can lead to failures where the path names become too long. As a temporary workaround, just remove the version string from the hash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152266 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-07AST representation for user-defined literals, plus just enough of semanticRichard Smith
analysis to make the AST representation testable. They are represented by a new UserDefinedLiteral AST node, which is a sugared CallExpr. All semantic properties, including full CodeGen support, are achieved for free by this representation. UserDefinedLiterals can never be dependent, so no custom instantiation behavior is required. They are mangled as if they were direct calls to the underlying literal operator. This matches g++'s apparent behavior (but not its actual mangling, which is broken for literal-operator-ids). User-defined *string* literals are now fully-operational, but the semantic analysis is quite hacky and needs more work. No other forms of user-defined literal are created yet, but the AST support for them is present. This patch committed after midnight because we had already hit the quota for new kinds of literal yesterday. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152211 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-07More git-svn compatible version string, by request.Andrew Trick
If you're using git-svn, the clang and llvm repository will typically map to a different revision. Before we had: clang version 3.1 (trunk 152167 trunk 152162) After this change: clang version 3.1 (trunk 152167) (llvm/trunk 152162) So it's self-descriptive with an extra parens group. Which is more compatible with version string parsers is probably debatable, but this style was requested. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152183 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-07Refactor Clang sema attribute handling.Michael Han
This submission improves Clang sema handling by using Clang tablegen to generate common boilerplate code. As a start, it implements AttributeList enumerator generation and case statements for AttributeList::getKind. A new field "SemaHandler" is introduced in Attr.td and by default set to 1 as most of attributes in Attr.td have semantic checking in Sema. For a small number of attributes that don't appear in Sema, the value is set to 0. Also there are a small number of attributes that only appear in Sema but not in Attr.td. Currently these attributes are still hardcoded in Sema AttributeList.

- These functions are both (a) very commonly called and (b) excellent candidates for CSE in the callers in which they are commonly used. - That isHalfType() is hot makes me sad, but it is trivially when inlined (and a huge waste of time when not!!!). - The extra IsEnumDeclComplete() function is a hack to break the cycle between Type.h and Decl.h, I'm not sure of how to do this more cleanly, but am open to ideas. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152126 91177308-0d34-0410-b5e6-96231b3b80d8
