* Move getInitialFrameState from TargetFrameInfo to MCAsmInfo (suggestions forEvan Cheng2011-07-181-17/+0

* * Redo the permutation encoding for frameless stacks to be more like what theBill Wendling2011-07-141-44/+73
| | | | | | | unwind library expects. * Comment the permutation encoding for frameless stacks. llvm-svn: 135202
* Add code to handle a "frameless" unwind stack.Bill Wendling2011-07-131-13/+55
| | | | | | | The frameless unwind stack has a special encoding, the algorithm for which is in "permuteEncode". llvm-svn: 135103

* Clean up the handling of an EBP/RBP unwind frame pointer. In particular, don'tBill Wendling2011-07-131-23/+26
