2012-03-08Fix a couple of issues with literal-operator-id parsing, and provide recoveryRichard Smith
for a few kinds of error. Specifically: Since we're after translation phase 6, the "" token might be formed by multiple source-level string literals. Checking the token width is not a correct way of detecting empty string literals, due to escaped newlines. Diagnose and recover from a missing space between "" and suffix, and from string literals other than "", which are followed by a suffix. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152348 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-08Taken into account Duncan's comments for r149481 dated by 2nd Feb 2012:Stepan Dyatkovskiy
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120130/136146.html Implemented CaseIterator and it solves almost all described issues: we don't need to mix operand/case/successor indexing anymore. Base iterator class is implemented as a template since it may be initialized either from "const SwitchInst*" or from "SwitchInst*". ConstCaseIt is just a read-only iterator. CaseIt is read-write iterator; it allows to change case successor and case value. Usage of iterator allows totally remove resolveXXXX methods. All indexing convertions done automatically inside the iterator's getters. Main way of iterator usage looks like this: SwitchInst *SI = ... // intialize it somehow for (SwitchInst::CaseIt i = SI->caseBegin(), e = SI->caseEnd(); i != e; ++i) { BasicBlock *BB = i.getCaseSuccessor(); ConstantInt *V = i.getCaseValue(); // Do something. } If you want to convert case number to TerminatorInst successor index, just use getSuccessorIndex iterator's method. If you want initialize iterator from TerminatorInst successor index, use CaseIt::fromSuccessorIndex(...) method. There are also related changes in llvm-clients: klee and clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152298 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-08Implement C++11 [lex.ext]p10 for string and character literals: a ud-suffix notRichard Smith
starting with an underscore is ill-formed. Since this rule rejects programs that were using <inttypes.h>'s macros, recover from this error by treating the ud-suffix as a separate preprocessing-token, with a DefaultError ExtWarn. The approach of treating such cases as two tokens is under discussion for standardization, but is in any case a conforming extension and allows existing codebases to keep building while the committee makes up its mind. Reword the warning on the definition of literal operators not starting with underscores (which are, strangely, legal) to more explicitly state that such operators can't be called by literals. Remove the special-case diagnostic for hexfloats, since it was both triggering in the wrong cases and incorrect. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152287 91177308-0d34-0410-b5e6-96231b3b80d8

As well as a list of Parentless/Unreachable functions, which are either truly unreachable or are unreachable due to our analyses imprecision.

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.

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.
