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

2009-04-27rdar://6827200 - [sema] reject statically allocated arrays of interface typesChris Lattner
Upgrade "array of interface" warning to an error. In addition to being a terrible idea, this crashes codegen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70178 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-23Add implicit definition of objc_msgSend.Daniel Dunbar
- As with malloc and friends, this is important where the return type on a 64-bit platform would otherwise end up discarding the upper 32-bits. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69874 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Reapply r69771, with updates & fixes:Daniel Dunbar
Rework the shadow struct that is layed out for Objective-C classes. - Superclasses are now always laid out in their shadow structure at the first field. - Prior to this, the entire class heirarchy was flattened into a single structure which meant that alignment, padding, and bitfields were incorrect (the ASTRecordLayout was correct however, which meant our debug info didn't coincide with ivar offsets, for example). - This is still very suboptimal (for example, ivar are looked up recursively, but I believe the ivar layout itself is now at least close to correct. - <rdar://problem/6773388> error: objc[29823]: layout bitmap sliding backwards git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69811 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-19Fix bug in computation of ivar offsets for (adjacent) bitfields.Daniel Dunbar

2009-04-15Tweaks to Objective-C metadata (32 & 64-bit) to match llvm-gcc.Daniel Dunbar
- Set alignment on property lists. - 32-bit: o Set section on property lists. o Fix section name for category class methods. o Fix symbol name for property lists. o Fix section name for class method. o Set alignment and section on class extension structure. o Set alignment on a number of things: instance variables, methods, method descriptions, the symbols structure. - 64-bit: o Fix section flags for protocol list. I doubt most of these were problems in practice, but it is nice to match llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69132 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-07Various fixes to symbols used for Obj-C x86_64 metadata.Daniel Dunbar
- Changed method names to match gcc (categories names still aren't mangled in). - Expose correct name for class and metadata symbols (although -fvisibility=hidden isn't yet correct). - Remove several things from llvm.used that didn't need to be there (I suspect this can still be trimmed). - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not needed). - Hide EH type class info with -fvisibility=hidden - Change setGlobal[Option]Visibility to not change the visibility of functions with internal linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68510 91177308-0d34-0410-b5e6-96231b3b80d8
