2012-06-19Improve the specification of spellings in Attr.td.Sean Hunt
Note that this is mostly a structural patch that handles the change from the old spelling style to the new one. One consequence of this is that all AT_foo_bar enum values have changed to not be based off of the first spelling, but rather off of the class name, so they are now AT_FooBar and the like (a straw poll on IRC showed support for this). Apologies for code churn. Most attributes have GNU spellings as a temporary solution until everything else is sorted out (such as a Keyword spelling, which I intend to add if someone else doesn't beat me to it). This is definitely a WIP. I've also killed BaseCheckAttr since it was unused, and I had to go through every attribute anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158700 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-13More doxygen/documentation cleanups.James Dennett
This reduces the number of warnings generated by Doxygen by about 100 (roughly 10%). Issues addressed: (1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments when they're not supposed to be Doxygen commands or links, and similarly for "<baz>" when it's not intended as as HTML tag; (2) Changed some \t commands (which don't exist) to \c ("to refer to a word of code", as the Doxygen manual says); (3) \precondition becomes \pre; (4) When touching comments, deleted a couple of spurious spaces in them; (5) Changed some \n and \r to \\n and \\r; (6) Fixed one tiny typo: #pragms -> #pragma. This patch touches documentation/comments only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158422 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-07Plug a long standing memory leak in TemplateArgument.Benjamin Kramer
The integral APSInt value is now stored in a decomposed form and the backing store for large values is allocated via the ASTContext. This way its not leaked as TemplateArguments are never destructed when they are allocated in the ASTContext. Since the integral data is immutable it is now shared between instances, making copying TemplateArguments a trivial operation. Currently getting the integral data out of a TemplateArgument requires creating a new APSInt object. This is cheap when the value is small but can be expensive if it's not. If this turns out to be an issue a more efficient accessor could be added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158150 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-16Include the correct conversion context locations for condition expressions.David Blaikie
This improves the conversion diagnostics (by correctly pointing to the loop construct for conversions that may've been caused by the contextual conversion to bool caused by a condition expression) and also causes the NULL conversion warnings to be correctly suppressed when crossing a macro boundary in such a context. (previously, since the conversion context location was incorrect, the suppression could not be performed) Reported by Nico Weber as feedback to r156826. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156901 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes PR12806 (we weren't setting the exception specification for an explicitly-defaulted, non-user-provided default constructor) and enforces 8.4.2/2's rule that an in-class defaulted member must exactly match the implicit parameter type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156802 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-10Fix an old (2009) FIXME:Rafael Espindola
// FIXME: This needs to happen before we merge declarations. Then, // let attribute merging cope with attribute conflicts. This was already being done for variables, but for functions we were merging then first and then applying the attributes. To avoid duplicating merging logic, some of the helpers in SemaDeclAttr.cpp become methods that can handle merging two attributes in one decl or inheriting attributes from one decl to another. With this change we are now able to produce errors for variables with incompatible visibility attributes or warn about unused dllimports in variables. This changes the attribute list iteration back to being in reverse source code order, as that matches what decl merging does and avoids differentiating the two cases is the merge*Attr methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156531 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-09[AST/libclang] Speed up clang_getOverriddenCursors() considerably by ↵Argyrios Kyrtzidis
reserving a bit in ObjCMethodDecl to indicate whether the method does not override any other method, which is the majority of cases. That way we can avoid unnecessary work doing lookups, especially when PCH is involved. rdar://11360082 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156476 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-07When we suppress an error due to SFINAE, stash the diagnostic away with theRichard Smith
overload candidate, and include its message in any subsequent 'candidate not viable due to substitution failure' note we may produce. To keep the note small (since the 'overload resolution failed' diagnostics are often already very verbose), the text of the SFINAE diagnostic is included as part of the text of the note, and any notes which were attached to it are discarded. There happened to be spare space in OverloadCandidate into which a PartialDiagnosticAt could be squeezed, and this patch goes to lengths to avoid unnecessary PartialDiagnostic copies, resulting in no slowdown that I could measure. (Removal in passing of some PartialDiagnostic copies has resulted in a slightly smaller clang binary overall.) Even on a torture test, I was unable to measure a memory increase of above 0.2%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156297 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-04Move Sema::RequireCompleteType() and Sema::RequireCompleteExprType()Douglas Gregor
off PartialDiagnostic. PartialDiagnostic is rather heavyweight for something that is in the critical path and is rarely used. So, switch over to an abstract-class-based callback mechanism that delays most of the work until a diagnostic is actually produced. Good for ~11k code size reduction in the compiler and 1% speedup in -fsyntax-only on the code in <rdar://problem/11004361>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156176 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-03Add -Wimplicit-fallthrough warning flag, which warns on fallthrough betweenRichard Smith
cases in switch statements. Also add a [[clang::fallthrough]] attribute, which can be used to suppress the warning in the case of intentional fallthrough. Patch by Alexander Kornienko! The handling of C++11 attribute namespaces in this patch is temporary, and will be replaced with a cleaner mechanism in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156086 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-01Eliminate Sema::CompareMethodParamsInBaseAndSuper() entirely, byDouglas Gregor

2012-05-01The semantic checking that verifies whether an Objective-C methodDouglas Gregor
declared in a subclass has consistent parameter types with a method having the same selector in a superclass performs a significant number of lookups into the class hierarchy. In the example in <rdar://problem/11004361>, we spend 4.7% of -fsyntax-only time in these lookups. Optimize away most of the calls to this routine (Sema::CompareMethodParamsInBaseAndSuper) by first checking whether we have ever seen *any* method with that selector (using the global selector table). Since most selectors are unique, we can avoid the cost of this name lookup in many cases, for a 3.3% speedup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155958 91177308-0d34-0410-b5e6-96231b3b80d8
