2012-02-04In C++11 mode, when an integral constant expression is desired and we have aRichard Smith
value of class type, look for a unique conversion operator converting to integral or unscoped enumeration type and use that. Implements [expr.const]p5. Sema::VerifyIntegerConstantExpression now performs the conversion and returns the converted result. Some important callers of Expr::isIntegralConstantExpr have been switched over to using it (including all of those required for C++11 conformance); this switch brings a side-benefit of improved diagnostics and, in several cases, simpler code. However, some language extensions and attributes have not been moved across and will not perform implicit conversions on constant expressions of literal class type where an ICE is required. In passing, fix static_assert to perform a contextual conversion to bool on its argument. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149776 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-04Don't allow a value of a scoped enumeration to be used as the first bound for anRichard Smith
array new expression. This lays some groundwork for the implicit conversion to integral or unscoped enumeration which C++11 ICEs undergo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149772 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-03Implement implicit capture for lambda expressions.Eli Friedman
Still left: explicit captures in lambdas need to cause implicit capture, and I need to take a look at the diagnostics for some cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149718 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-03When a pack expansion occurs in the template argument list of an aliasDouglas Gregor
template without a corresponding parameter pack, don't immediately substitute the alias template. This is under discussion in the C++ committee, and may become ill-formed, but for now we match GCC. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149697 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-01Add a new compiler warning, which flags anti-patterns used as the sizeAnna Zaks
argument in strncat. The warning is ignored by default since it needs more qualification. TODO: The warning message and the note are messy when strncat is a builtin due to the macro expansion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149524 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01Introduce the lambda scope before determining explicit captures, whichDouglas Gregor
cleans up and improves a few things: - We get rid of the ugly dance of computing all of the captures in data structures that clone those of CapturingScopeInfo, centralizing the logic for accessing/updating these data structures - We re-use the existing capture logic for 'this', which actually works now. Cleaned up some diagnostic wording in minor ways as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149516 91177308-0d34-0410-b5e6-96231b3b80d8

No new unit tests yet as there is no behavioral change (except for slightly more specific filtering in Sema::ActOnStartOfLambdaDefinition).

2012-01-12Improve 0-argument -Wvexing-parse diagnostic by adding notes with fix-its:Richard Smith
- If the declarator is at the start of a line, and the previous line contained another declarator and ended with a comma, then that comma was probably a typo for a semicolon: int n = 0, m = 1, l = 2, // k = 5; myImportantFunctionCall(); // oops! - If removing the parentheses would correctly initialize the object, then produce a note suggesting that fix. - Otherwise, if there is a simple initializer we can suggest which performs value-initialization, then provide a note suggesting a correction to that initializer. Sema::Declarator now tracks the location of the comma prior to the declarator in the declaration, if there is one, to facilitate providing the note. The code to determine an appropriate initializer from the -Wuninitialized warning has been factored out to allow use in both that and -Wvexing-parse. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148072 91177308-0d34-0410-b5e6-96231b3b80d8
