2013-02-20Use LiveRangeUpdater instead of mergeIntervalRanges.Jakob Stoklund Olesen
Performance is the same, but LiveRangeUpdater has a more flexible interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175645 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-20Add a LiveRangeUpdater class.Jakob Stoklund Olesen
Adding new segments to large LiveIntervals can be expensive because the LiveRange objects after the insertion point may need to be moved left or right. This can cause quadratic behavior when adding a large number of segments to a live range. The LiveRangeUpdater class allows the LIveInterval to be in a temporary invalid state while segments are being added. It maintains an internal gap in the LiveInterval when it is shrinking, and it has a spill area for new segments when the LiveInterval is growing. The behavior is similar to the existing mergeIntervalRanges() function, except it allocates less memory for the spill area, and the algorithm is turned inside out so the loop is driven by the clients. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175644 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-20Fix PR15267Michael Liao
- When extloading from a vector with non-byte-addressable element, e.g. <4 x i1>, the current logic breaks. Extend the current logic to fix the case where the element type is not byte-addressable by loading all bytes, bit-extracting/packing each element. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175642 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-20Fix bug 14779 for passing anonymous aggregates [patch by Kai Nacke].Bill Schmidt
The PPC backend doesn't handle these correctly. This patch uses logic similar to that in the X86 and ARM backends to track these arguments properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175635 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-20Fix PR15155: lost vadd/vsplat optimization.Bill Schmidt
During lowering of a BUILD_VECTOR, we look for opportunities to use a vector splat. When the splatted value fits in 5 signed bits, a single splat does the job. When it doesn't fit in 5 bits but does fit in 6, and is an even value, we can splat on half the value and add the result to itself. This last optimization hasn't been working recently because of improved constant folding. To circumvent this, create a pseudo VADD_SPLAT that can be expanded during instruction selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175632 91177308-0d34-0410-b5e6-96231b3b80d8

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

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.
