* Simplify landing pad lowering.Jakob Stoklund Olesen2013-07-041-0/+5
| | | | | | | | | | | | | | | | | | | | | Stop using the ISD::EXCEPTIONADDR and ISD::EHSELECTION when lowering landing pad arguments. These nodes were previously legalized into CopyFromReg nodes, but that never worked properly because the CopyFromReg node weren't guaranteed to be scheduled at the top of the basic block. This meant the exception pointer and selector registers could be clobbered before being copied to a virtual register. This patch copies the two physical registers to virtual registers at the beginning of the basic block, and lowers the landingpad instruction directly to two CopyFromReg nodes reading the *virtual* registers. This is safe because virtual registers don't get clobbered. A future patch will remove the ISD::EXCEPTIONADDR and ISD::EHSELECTION nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185617 91177308-0d34-0410-b5e6-96231b3b80d8

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-2/+2
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8
* Change TargetLowering::getRegClassFor to take an MVT, instead of EVT.Patrik Hagglund2012-12-131-1/+1
| | | | | | | | | | | | | Accordingly, add helper funtions getSimpleValueType (in parallel to getValueType) in SDValue, SDNode, and TargetLowering. This is the first, in a series of patches. This is the second attempt. In the first attempt (r169837), a few getSimpleVT() were hoisted too far, detected by bootstrap failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170104 91177308-0d34-0410-b5e6-96231b3b80d8

* Add the support in code-gen for the landingpad instruction lowering.Bill Wendling2011-08-171-0/+5
| | | | | | | | | | | The landingpad instruction is lowered into the EXCEPTIONADDR and EHSELECTION SDNodes. The information from the landingpad instruction is harvested by the 'AddLandingPadInfo' function. The new EH uses the current EH scheme in the back-end. This will change once we switch over to the new scheme. (Reviewed by Jakob!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137880 91177308-0d34-0410-b5e6-96231b3b80d8

Modify the code to more thoroughly check for an 'eh.selector' call in successors. It only looks at a successor if we get there as a result of an unconditional branch.
