2013-03-26<rdar://problem/13267210> Ensure that Sema::CompareReferenceRelationship ↵Douglas Gregor
returns consistent results with invalid types. When Sema::RequireCompleteType() is given a class template specialization type that then fails to instantiate, it returns 'true'. On subsequent invocations, it can return false. Make sure that this difference doesn't change the result of Sema::CompareReferenceRelationship, which is expected to remain stable while we're checking an initialization sequence. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178088 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-15Teach the uninitialized field warning about anonymous structs and union members.Nick Lewycky
Fixes PR14073! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168031 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-21Make warnings about uninitialized fields include the field name.Hans Wennborg
This makes the wording more informative, and consistent with the other warnings about uninitialized variables. Also, me and David who reviewed this couldn't figure out why we would need to do a lookup to get the name of the variable; so just print the name directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164366 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-30Reapply r107235, this time with both my typo fixed, and a logical bug fixed.Chandler Carruth
Previously we relied on the presence of a member which needs no initialization to prevent us from creating an additional initialization of the outer anonymous union field. We have already correctly marked that field as initialized by the member of the union (repeatedly due to the original bug this patch fixes) so we simply need to bail out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107242 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-30Fix PR7402: We were creating implicit member initializers for every field in anChandler Carruth
anonymous union under the presumption that they didn't do anything. While this is true, our checks for redundant initialization of an anonymous union still fire when these overlap with explicit user initialization. A cleaner approach is to avoid initializing multiple members of a union altogether, but this still is in a rather fuzzy are especially when C++0x allows non-POD types into unions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107235 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-10Diagnose more cases of initializing distinct members of an anonymous unionJohn McCall
member. Use a better diagnostic for this case. Also fix a bug with nested anonymous structs/unions for -Wreorder; this last was PR6575. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100923 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-10Diagnose misordered initializers in constructor templates immediately instead ofJohn McCall
when they're instantiated. Merge the note into the -Wreorder warning; it doesn't really contribute much, and it was splitting a thought across diagnostics anyway. Don't crash in the parser when a constructor's initializers end in a comma and there's no body; the recovery here is still terrible, but anything's better than a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100922 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-31Rework base and member initialization in constructors, with severalDouglas Gregor
(necessarily simultaneous) changes: - CXXBaseOrMemberInitializer now contains only a single initializer rather than a set of initialiation arguments + a constructor. The single initializer covers all aspects of initialization, including constructor calls as necessary but also cleanup of temporaries created by the initializer (which we never handled before!). - Rework + simplify code generation for CXXBaseOrMemberInitializers, since we can now just emit the initializer as an initializer. - Switched base and member initialization over to the new initialization code (InitializationSequence), so that it - Improved diagnostics for the new initialization code when initializing bases and members, to match the diagnostics produced by the previous (special-purpose) code. - Simplify the representation of type-checked constructor initializers in templates; instead of keeping the fully-type-checked AST, which is rather hard to undo at template instantiation time, throw away the type-checked AST and store the raw expressions in the AST. This simplifies instantiation, but loses a little but of information in the AST. - When type-checking implicit base or member initializers within a dependent context, don't add the generated initializers into the AST, because they'll look like they were explicit. - Record in CXXConstructExpr when the constructor call is to initialize a base class, so that CodeGen does not have to infer it from context. This ensures that we call the right kind of constructor. There are also a few "opportunity" fixes here that were needed to not regress, for example: - Diagnose default-initialization of a const-qualified class that does not have a user-declared default constructor. We had this diagnostic specifically for bases and members, but missed it for variables. That's fixed now. - When defining the implicit constructors, destructor, and copy-assignment operator, set the CurContext to that constructor when we're defining the body. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94952 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-13Improve the reporting of non-viable overload candidates by noting the reasonJohn McCall
why the candidate is non-viable. There's a lot we can do to improve this, but it's a good start. Further improvements should probably be integrated with the bad-initialization reporting routines. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93277 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-06Improve the diagnostics used to report implicitly-generated class membersJohn McCall
as parts of overload sets. Also, refer to constructors as 'constructors' rather than functions. Adjust a lot of tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92832 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-09Unify the codepaths used to verify base and member initializers for explicitlyEli Friedman
and implicitly defined constructors. This has a number of benefits: 1. Less code. 2. Explicit and implicit constructors get the same diagnostics. 3. The AST explicitly contains constructor calls from implicit default constructors. This allows handing some cases that previously weren't handled correctly in IRGen without any additional code. Specifically, implicit default constructors containing calls to constructors with default arguments are now handled correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86500 91177308-0d34-0410-b5e6-96231b3b80d8
