2011-07-26The compact unwinding offsets are divided by 8 on 64-bit machines.Bill Wendling

2011-07-25Update the comment. This feature is available only on Darwin at the moment. ↵Bill Wendling
Though it's not Darwin-specific. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135951 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-25After we've modified the prolog to save volatile registers, generate the compactBill Wendling
unwind encoding for that function. This simply crawls through the prolog looking for machine instrs marked as "frame setup". It can calculate from these what the compact unwind should look like. This is currently disabled because of needed linker support. But initial tests look good. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135922 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-18Move getInitialFrameState from TargetFrameInfo to MCAsmInfo (suggestions forEvan Cheng
better location welcome). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135438 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14* Redo the permutation encoding for frameless stacks to be more like what theBill Wendling
unwind library expects. * Comment the permutation encoding for frameless stacks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135202 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Add code to handle a "frameless" unwind stack.Bill Wendling
The frameless unwind stack has a special encoding, the algorithm for which is in "permuteEncode". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135103 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-13Clean up the handling of an EBP/RBP unwind frame pointer. In particular, don'tBill Wendling
assert when the frame pointer is -1 (i.e., the function is "frameless"). Still to do: "frameless" unwind information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135013 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-12Put FrameSetup flag on x86 instructions that set up the call frame. NoCharles Davis
functionality change. Later on, we'll use the flag to emit SEH pseudo-ops that describe how the call frame was built. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132880 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-15Add 129518 back with a fix for when we are producing eh just because of ↵Rafael Espindola
