dispatch arguments which have sentinel attribute. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71737 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-13Add some basic type checking for attributes ns_returns_retained andTed Kremenek
cf_returns_retained. Currently this attribute can now be applied to any Objective-C method or C function that returns a pointer or Objective-C object type. Modify the tablegen definition of diagnostic 'warn_attribute_wrong_decl_type' to expect that the diagnostics infrastructure will add quotes around the attribute name when appropriate. Alonq with this change, I modified the places where this warning is issued to passed the attribute's IdentifierInfo* instead of having a hard-coded C constant string. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71718 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-13Fix rdar://6880951 by rejecting vectors of vectors.Chris Lattner
It seems dubious to me that isIntegerType() returns true for vectors of integers, but not complex integers. This should probably be rethought, I'll file a bugzilla. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-13Fix rdar://6881069, a crash on a form of vector_size that weChris Lattner
don't support. While it would be nice to support this eventually, this form is not common at all (just seen in gcc testsuite) and it might be better to model vector_size as a type attribute anyway. For now just emit a nice error on it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71633 91177308-0d34-0410-b5e6-96231b3b80d8

ns_returns_retained, but do not include the other ownership attributes we previously had. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71308 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-04Rename attributes 'objc_ownership...' to 'ns_ownership...'.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70897 91177308-0d34-0410-b5e6-96231b3b80d8
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

2009-04-25Add 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

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.

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
