Richard Smith f4c51d9d76 In C++11 mode, when an integral constant expression is desired and we have a ... 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. llvm-svn: 149776		2012-02-04 09:53:13 +00:00
