* R600: improve inputs/interpolation handlingTom Stellard2013-02-0510-252/+130
| | | | | | | | | | | | | | | | | 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.

* Support: ensure proper state in ErrorOr copy ctors before calling 'get'Meador Inge2013-02-051-7/+4
| | | | | | | | | | | Some paths through the copy constructors for 'ErrorOr' were calling 'get' when 'HasError' and 'IsValid' were not properly initialized. Depending on what happened to be in memory for those member variables the asserts in 'get' might incorrectly fire. Fixed by ensuring that the member variables in question are always initialized before calling 'get'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174381 91177308-0d34-0410-b5e6-96231b3b80d8

* Loop Vectorizer: Handle pointer stores/loads in getWidestType()Arnold Schwaighofer2013-02-052-9/+180
| | | | | | | | | | | | | | | | | 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

* When the target-independent DAGCombiner inferred a higher alignment for a load,Owen Anderson2013-02-053-6/+10
| | | | | | | | | | | | 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.
