claims it will improve performance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174341 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02PR15132: Replace "address expression must be an lvalue or a functionRichard Smith
designator" diagnostic with more correct and more human-friendly "cannot take address of rvalue of type 'T'". For the case of & &T::f, provide a custom diagnostic, rather than unhelpfully saying "cannot take address of rvalue of type '<overloaded function type>'". For the case of &array_temporary, treat it just like a class temporary (including allowing it as an extension); the existing diagnostic wording for the class temporary case works fine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174262 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02This patch makes "&Cls::purevfn" not an odr use. This isn't what the standardNick Lewycky
says, but that's a defect (to be filed). "Cls::purevfn()" is still an odr use. Also fixes a bug that caused us to not mark the function referenced just because we didn't want to mark it odr used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174242 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01Fix PR14881 by implementing conversion rules between int and complex int.Bill Schmidt
Prior to the patch, Clang does not properly promote types when a complex integer operand is combined with an integer via a binary operator, or when one is assigned to the other in either order. This patch detects when promotion is needed (and permissible) and generates the necessary code. The test assmes no target has the same size operands for "char" and "long long," and that no target performs arithmetic on char operands without extending them to a larger format first. If there are any targets for which this is not the case, they should be XFAILed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174181 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30Provide a fixit for constexpr non-static data members.David Blaikie
If the member has an initializer, assume it was probably intended to be static and suggest/recover with that. If the member doesn't have an initializer, assume it was probably intended to be const instead of constexpr and suggest that. (if the attempt to apply these changes fails, don't make any suggestion & produce the same diagnostic experience as before. The only case where this can come up that I know of is with a mutable constexpr with an initializer, since mutable is incompatible with static (but it's already incompatible with const anyway)) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173873 91177308-0d34-0410-b5e6-96231b3b80d8
