| * Move the eliminateCallFramePseudoInstr method from TargetRegisterInfoEli Bendersky2013-02-214-107/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to TargetFrameLowering, where it belongs. Incidentally, this allows us to delete some duplicated (and slightly different!) code in TRI. There are potentially other layering problems that can be cleaned up as a result, or in a similar manner. The refactoring was OK'd by Anton Korobeynikov on llvmdev. Note: this touches the target interfaces, so out-of-tree targets may be affected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175788 91177308-0d34-0410-b5e6-96231b3b80d8
| * getX86SubSuperRegister has a special mode with High=true for i64 whichEli Bendersky2013-02-211-17/+9
| | | | | | | | | | | | | | | | | | | | | | | | exists solely to enable it to call itself for i8 with some registers. The proposed patch simplifies the function somewhat to make the High bit only meaningful for the i8 mode, which makes sense. No functional difference (getX86SubSuperRegister is not getting called from anywhere outside with i64 and High=true). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175762 91177308-0d34-0410-b5e6-96231b3b80d8

The "sar" does not exist on 64-bit operation, so lowering sext_in_reg (v4i64 x) has no vector solution. I also added a cost of this operations to the AVX costs table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175619 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | MS-style inline assembly. This is a follow-on to r175334. Forcing a FP to be emitted doesn't ensure it will be used. Therefore, force the base pointer as well. We now treat MS inline assembly in the same way we treat functions with dynamic stack realignment and VLAs. This guarantees the BP will be used to reference parameters and locals. rdar://13218191 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175576 91177308-0d34-0410-b5e6-96231b3b80d8
