Large code model is identical to medium code model except that the addis/addi sequence for "local" accesses is never used. All accesses use the addis/ld sequence.

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 constructs %hi() and %lo() represent the high and low 16 bits of the address. Because the 16 bit offset field of an LW instruction is interpreted as signed, if bit 15 of the low part is 1 then the low part will act as a negative and 1 needs to be added to the high part.

2013-02-21PPCDAGToDAGISel::PostprocessISelDAG()Bill Schmidt
This patch implements the PPCDAGToDAGISel::PostprocessISelDAG virtual method to perform post-selection peephole optimizations on the DAG representation. One optimization is implemented here: folds to clean up complex addressing expressions for thread-local storage and medium code model. It will also be useful for large code model sequences when those are added later. I originally thought about doing this on the MI representation prior to register assignment, but it's difficult to do effective global dead code elimination at that point. DCE is trivial on the DAG representation. A typical example of a candidate code sequence in assembly: addis 3, 2, globalvar@toc@ha addi 3, 3, globalvar@toc@l lwz 5, 0(3) When the final instruction is a load or store with an immediate offset of zero, the offset from the add-immediate can replace the zero, provided the relocation information is carried along: addis 3, 2, globalvar@toc@ha lwz 5, globalvar@toc@l(3) Since the addi can in general have multiple uses, we need to only delete the instruction when the last use is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175697 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

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

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.
