* Validate target data layout strings.Lang Hames2011-10-172-25/+94
| | | | | | | Invalid strings in asm files will result in parse errors. Invalid string literals passed to TargetData constructors will result in an assertion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142288 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for the Objective-C personality function to the instructionBill Wendling2011-10-171-2/+5
| | | | | | | | | combining of the landingpad instruction. The ObjC personality function acts almost identically to the C++ personality function. In particular, it uses "null" as a "catch-all" value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142256 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a call to EmitSjLjDispatchBlock.Bill Wendling2011-10-171-0/+8
| | | | | | | | Once the intrinsics are marked as having a custom inserter, it will call this method to emit the dispatch table into the machine function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142245 91177308-0d34-0410-b5e6-96231b3b80d8
