2013-02-05R600: improve inputs/interpolation handlingTom Stellard
Use one intrinsic for all sorts of interpolation. Use two separate unexpanded instructions to represent INTERP_XY and _ZW - this will allow to eliminate one part if it's not used. Track liveness of special interpolation regs instead of reserving them - this will allow to reuse those regs, lowering reg pressure.

2013-02-05Loop Vectorizer: Handle pointer stores/loads in getWidestType()Arnold Schwaighofer
In the loop vectorizer cost model, we used to ignore stores/loads of a pointer type when computing the widest type within a loop. This meant that if we had only stores/loads of pointers in a loop we would return a widest type of 8bits (instead of 32 or 64 bit) and therefore a vector factor that was too big. Now, if we see a consecutive store/load of pointers we use the size of a pointer (from data layout). This problem occured in SingleSource/Benchmarks/Shootout-C++/hash.cpp (reduced test case is the first test in vector_ptr_load_store.ll). radar://13139343 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174377 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-05When the target-independent DAGCombiner inferred a higher alignment for a load,Owen Anderson
it would replace the load with one with the higher alignment. However, it did not place the new load in the worklist, which prevented later DAG combines in the same phase (for example, target-specific combines) from ever seeing it. This patch corrects that oversight, and updates some tests whose output changed due to slightly different DAGCombine outputs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174343 91177308-0d34-0410-b5e6-96231b3b80d8

Per discussion in rdar://13127907, we should emit a hard error only if people write code where the requested alignment is larger than achievable and assumes the low bits are zeros.

2013-02-04SelectionDAG: Teach FoldConstantArithmetic how to deal with vectors.Benjamin Kramer
This required disabling a PowerPC optimization that did the following: input: x = BUILD_VECTOR <i32 16, i32 16, i32 16, i32 16> lowered to: tmp = BUILD_VECTOR <i32 8, i32 8, i32 8, i32 8> x = ADD tmp, tmp The add now gets folded immediately and we're back at the BUILD_VECTOR we started from. I don't see a way to fix this currently so I left it disabled for now.
