2009-05-04Rename attributes:Ted Kremenek
'objc_ownership_cfretain' -> 'cf_ownership_retain' 'objc_ownership_cfrelease' -> 'cf_ownership_release' Motivation: Core Foundation objects can be used in isolation from Objective-C, and this forces users to reason about the separate semantics of CF objects. More Sema support pending. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70884 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-04Remove support for ObjCMethodDecl attributes that appear between theTed Kremenek
return type and the selector. This is inconsistent with C functions (where such attributes would be placed on the return type, not the the FunctionDecl), and is inconsistent with what people are use to seeing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70878 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-30Allow attributes 'objc_ownership_retain' and 'objc_ownership_release' to beTed Kremenek
applied to ObjCMethodDecls, not just parameters. This allows one to specific side-effects on the receiver of a message expression. No checker support yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70505 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-30Hook up Sema support for attributes on Objective-C method declarations thatTed Kremenek
appear between the return type and the selector. This is a separate code path from regular attribute processing, as we only want to (a) accept only a specific set of attributes in this place and (b) want to distinguish to clients the context in which an attribute was added to an ObjCMethodDecl. Currently, the attribute 'objc_ownership_returns' is the only attribute that uses this new feature. Shortly I will add a warning for 'objc_ownership_returns' to be placed at the end of a method declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29Implement semantic analysis for transparent unions. This is largelyDouglas Gregor
based on a patch from Anders Johnsen. CodeGen support is incomplete, in that we do not properly coerce to the first field's type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70419 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29Sema and CodeGen support for attributes on blocks. Radar 6441502Mike Stump
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70403 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28Implement ownership attribute 'objc_ownership_make_collectable'. This allows oneTed Kremenek
to add 'CFMakeCollectable' semantics to a method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70336 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28Improve compatibility with GCC regarding inline semantics in GNU89Douglas Gregor
mode and in the presence of __gnu_inline__ attributes. This should fix both PR3989 and PR4069. As part of this, we now keep track of all of the attributes attached to each declaration even after we've performed declaration merging. This fixes PR3264. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70292 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-27Add two new checker-specific attributes: 'objc_ownership_release' andTed Kremenek
'objc_ownership_cfrelease'. These are the 'release' equivalents of 'objc_ownership_retain' and 'objc_ownership_cfretain' respectively. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70235 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-27Refactor HandleObjCOwnershipRetainAttr and HandleObjCOwnershipCFRetainAttr intoTed Kremenek
HandleObjCOwnershipParmAttr. No functionality change (hopefully). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70224 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-27Add new checker-specific attribute 'objc_ownership_cfretain'. This is the sameTed Kremenek
as 'objc_ownership_cfretain' except that the method acts like a CFRetain instead of a [... retain] (important in GC modes). Checker support is wired up, but currently only for Objective-C message expressions (not function calls). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70218 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26Correct the order of the parameters to CheckAssignmentConstraints in Eli Friedman
cleanup attribute checking. The difference isn't normally visible, but it can make a difference... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70104 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-25Add new checker-specific attribute 'objc_ownership_retain'. This isn't hooked upTed Kremenek
to the checker yet, but essentially it allows a user to specify that an Objective-C method or C function increments the reference count of a passed object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70005 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-24Add new checker-specific attribute 'objc_ownership_returns'. This isn't hookedTed Kremenek
up to the checker yet, but essentially it allows a user to specify that an Objective-C method or C function returns an owned an Objective-C object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70001 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Fix handling of C99 "extern inline" semantics when dealing withDouglas Gregor
multiple declarations of the function. Should fix PR3989 and <rdar://problem/6818429>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69905 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Fix some mishandling of the attr(gnu_inline) mode when used withChris Lattner
extern. Previously we would warn about it and ignore the attribute. This is incorrect, it should be handled as a c89 "extern inline" function. Many thanks to Matthieu Castet for pointing this out and beating me over the head until I got it.

2009-04-18FunctionDecl::getBody() is getting an ASTContext argument for use inDouglas Gregor

2009-04-10Implement attribute "analyzer_noreturn" (<rdar://problem/6777003>). This allowsTed Kremenek
clients of the analyzer to designate custom assertion routines as "noreturn" functions from the analyzer's perspective but not the compiler's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68746 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04Switch attributes to be allocated from the declcontext bump pointer just likeChris Lattner
decls. This reduces the number of calls to malloc on cocoa.h with pth and -disable-free from 15958 to 12444 times (down ~3500). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66023 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03PR3691: Add support for complex modes. I also tossed in support for XF Eli Friedman
while I was at it. There are still a lot of diagnostics missing from this code, and it isn't completely correct for anything other than x86, but it should work correctly on x86 for valid cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65935 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-26Create a new TypeNodes.def file that enumerates all of the types,Douglas Gregor
giving them rough classifications (normal types, never-canonical types, always-dependent types, abstract type representations) and making it far easier to make sure that we've hit all of the cases when decoding types. Switched some switch() statements on the type class over to using this mechanism, and filtering out those things we don't care about. For example, CodeGen should never see always-dependent or non-canonical types, while debug info generation should never see always-dependent types. More switch() statements on the type class need to be moved over to using this approach, so that we'll get warnings when we add a new type then fail to account for it somewhere in the compiler. As part of this, some types have been renamed: TypeOfExpr -> TypeOfExprType FunctionTypeProto -> FunctionProtoType FunctionTypeNoProto -> FunctionNoProtoType There shouldn't be any functionality change... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65591 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-14Several related changes: Chris Lattner
1) implement parser and sema support for reading and verifying attribute(warnunusedresult). 2) rename hasLocalSideEffect to isUnusedResultAWarning, inverting the sense of its result. 3) extend isUnusedResultAWarning to directly return the loc and range info that should be reported to the user. Make it substantially more precise in some cases than what was previously reported. 4) teach isUnusedResultAWarning about CallExpr to decls that are pure/const/warnunusedresult, fixing a fixme. 5) change warn_attribute_wrong_decl_type to not pass in english strings, instead, pass in integers and use %select. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64543 91177308-0d34-0410-b5e6-96231b3b80d8
