2009-04-30Make a home for exception specs in the AST. Now Sema can hook them up.Sebastian Redl
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70506 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

2009-04-30initial support for __[u]int128_t, which should be basicallyChris Lattner
compatible with VC++ and GCC. The codegen/mangling angle hasn't been fully ironed out yet. Note that we accept int128_t even in 32-bit mode, unlike gcc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70464 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-29Fix PR4092 by improving error recovery in two ways:Chris Lattner
1. In a struct field redefinition, don't mark the struct erroneous. The field is erroneous, but the struct is otherwise well formed. 2. Don't emit diagnostics about functions that are known to be broken already. Either fix is sufficient to silence the second diagnostic in the example, but the combination is better :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70371 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
2009-04-28Fix a minor edge case in C89 mode related to the definition of a Eli Friedman
"function designator". (This causes a minor glitch in the diagnostics for C++ member pointers, but we weren't printing the right diagnostic there anyway.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70307 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

2009-04-28Get rid of some useless uses of NoExtensions. The philosophy here is Eli Friedman
that if we're going to print an extension warning anyway, there's no point to changing behavior based on NoExtensions: it will only make error recovery worse. Note that this doesn't cause any behavior change because NoExtensions isn't used by the current front-end. I'm still considering what to do about the remaining use of NoExtensions in IdentifierTable.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70273 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-27Add two new checker-specific attributes: 'objc_ownership_release' andTed Kremenek

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

before r69391: typedef redefinition is an error by default, but if *either* the old or new definition are from a system header, we silence it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70177 91177308-0d34-0410-b5e6-96231b3b80d8
