2013-04-01PR15633: Note that we are EnteringContext when parsing the nested nameRichard Smith
specifier for an enumeration. Also fix a crash-on-invalid if a non-dependent name specifier is used to declare an enum template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178502 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-19Relaxed enumeration constant naming rules for scoped enumerators so they no ↵Aaron Ballman
longer emit a diagnostic when the enumeration's name matches that of the class. Fixes PR13128. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160490 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-26Handle instantiations of redeclarations of forward-declared enumerations withinRichard Smith
templated functions. Build a redeclaration chain, and only instantiate the definition of the enum when visiting the defining declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153427 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-26Delay checking of dependent underlying types for redeclarations of memberRichard Smith
enumerations in templates until the template is instantiated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153426 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-23When defining a forward-declared enum, don't try to attach the definition toRichard Smith
a previous declaration if the redeclaration is invalid. That way lies madness. Fixes a crash-on-invalid reported by Abramo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153349 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-10Slightly tweak this condition. "isTransparentContext()" was checking whether anNick Lewycky
enum is scoped or not, which is not relevant here. Instead, phrase the loop in the same terms that the standard uses, instead of this awkward set of conditions that is *nearly* equal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152489 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-08Loosen the precondition of isCXXInstanceMember() to simply returnDouglas Gregor
"false" for declarations that aren't members of classes. Fixes PR12106. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152284 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
2012-01-18constexpr: converted constant expression handling for enumerator values, caseRichard Smith
values and non-type template arguments of integral and enumeration types. This change causes some legal C++98 code to no longer compile in C++11 mode, by enforcing the C++11 rule that narrowing integral conversions are not permitted in the final implicit conversion sequence for the above cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148439 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-10Update C++11 scoped enumeration support to match the final proposal:Richard Smith
- reject definitions of enums within friend declarations - require 'enum', not 'enum class', for non-declaring references to scoped enumerations git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147824 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06Make sure we perform lvalue-to-rvalue conversions for enum initializers. ↵Eli Friedman
PR11484. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145874 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-13Update all tests other than Driver/std.cpp to use -std=c++11 rather thanRichard Smith
-std=c++0x. Patch by Ahmed Charles! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141900 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-06Fixed enum types can be complete without actually being valid to useJohn McCall
as scope specifiers; diagnose the attempt, rather than letting it go to an assert. The rest of PR10264. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134479 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-06Properly protect colons when parsing a nested-name-specifier as partJohn McCall
of an enum specifier in dialects which permit fixed underlying types. Fixes the rejects-valid part of PR10264. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134468 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-05Scoped enumerations should not be treated as integer types (in the CDouglas Gregor
sense). Fixes <rdar://problem/9366066> by eliminating an inconsistency between C++ overloading (which handled scoped enumerations correctly) and C binary operator type-checking (which didn't). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130924 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-01Implement comparison of C++0x scoped enumeration types. Fixes PR9333.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126752 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-22Fix a little bug in the handling of enumeration types with a fixedDouglas Gregor
underlying type: we weren't parsing unnamed enumeration types with a fixed underlying type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126184 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-08Implement C++0x scoped enumerations, from Daniel Wallin! (and tweaked aDouglas Gregor
bit by me). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116122 91177308-0d34-0410-b5e6-96231b3b80d8
