* Add the sentinal "no handle" value to the ResumeInst.Bill Wendling2011-08-241-0/+2
| | | | | | | | | A value of -1 at a call site tells the personality function that this call isn't handled by the current function. Since the ResumeInsts are converted to calls to _Unwind_SjLj_Resume, add a (volatile) store of -1 to its 'call site'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138416 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't replace *all* uses with the new stuff.Bill Wendling2011-08-231-1/+1
| | | | | | | | | This is not necessarily the first or dominating use of the EH values. The IR breaks if it's not. So replace the specific value in the instruction with the new value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138406 91177308-0d34-0410-b5e6-96231b3b80d8
* Look at the end of the entry block for an invoke.Bill Wendling2011-08-231-4/+17
| | | | | | | | | The invoke could be at the end of the entry block. If it's the only one, then we won't process all of the landingpad instructions correctly. This code is currently ugly, but should be made much nicer once the new EH switch is thrown. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138397 91177308-0d34-0410-b5e6-96231b3b80d8

* Move ARM frame-unwinding EHABI handling a touch earlier.Jim Grosbach2011-08-231-4/+4
