2013-02-20I optimized the following patterns:Elena Demikhovsky
sext <4 x i1> to <4 x i64> sext <4 x i8> to <4 x i64> sext <4 x i16> to <4 x i64> I'm running Combine on SIGN_EXTEND_IN_REG and revert SEXT patterns: (sext_in_reg (v4i64 anyext (v4i32 x )), ExtraVT) -> (v4i64 sext (v4i32 sext_in_reg (v4i32 x , ExtraVT))) The sext_in_reg (v4i32 x) may be lowered to shl+sar operations. 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

2013-02-20Fix thumbv5e frame lowering assertion failure.Logan Chien
It is possible that frame pointer is not found in the callee saved info, thus FramePtrSpillFI may be incorrect if we don't check the result of hasFP(MF). Besides, if we enable the stack coloring algorithm, there will be an assertion to ensure the slot is live. But in the test case, %var1 is not live in the prologue of the function, and we will get the assertion failure. Note: There is similar code in ARMFrameLowering.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175616 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-20Add support to the two-address pass for updating LiveIntervals in many of theCameron Zwarich

2013-02-20Add SlotIndexes::repairIndexesInRange(), which repairs SlotIndexes after addingCameron Zwarich

2013-02-19[ms-inline asm] Force the use of a base pointer if the MachineFunction includesChad Rosier
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

2013-02-19ELF symbol table field st_other support, Jack Carter
excluding visibility bits. Generic STO handling at the Target level. The st_other field of the ELF symbol table is one byte in size. The first 2 bytes are used for generic visibility and are currently handled by llvm. The other six bits are processor specific and need to be set at the target level. A couple of notes: The new static methods for accessing and setting the "other" flags in include/llvm/MC/MCELF.h match the style guide and not the other methods in the file. I don't like the inconsistency, but feel I should follow the prescribed lowerUpper() convention. STO_ value definitions are not specified in gnu land as consistently as the STT_ and STB_ fields. Probably because the latter were defined in a standards doc and the former defined partially in code. I have stuck with the full byte definition of the flags.

2013-02-19ARM NEON: Don't need COPY_TO_REGCLASS in patternArnold Schwaighofer
In my previous commit: "Merge a f32 bitcast of a v2i32 extractelt A vectorized sitfp on doubles will get scalarized to a sequence of an extract_element of <2 x i32>, a bitcast to f32 and a sitofp. Due to the the extract_element, and the bitcast we will uneccessarily generate moves between scalar and vector registers." I added a pattern containing a copy_to_regclass.
