2011-06-12Fix a bug in the calculation of the vectorTypeBreakdown into registers. OddNadav Rotem
types such as i33 were rounded to i32. Originated from Duncan's testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132893 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-12Improve the generated code by getCopyFromPartsVector for promoted integer types.Nadav Rotem
Instead of scalarizing, and doing an element-by-element truncat, use vector truncate. Add support for scalarization of vectors: i8 -> <1 x i1> (from Duncan's testcase). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132892 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-09Change this DAGCombine to build AND of SHR instead of SHR of AND; this ↵Eli Friedman
matches the ordering we prefer in instcombine. Part of rdar://9562809. The potential DAGCombine which enforces this more generally messes up some other very fragile patterns, so I'm leaving that alone, at least for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132809 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-01This patch is another step in the direction of adding vector select. In thisNadav Rotem
patch we add a flag to enable a new type legalization decision - to promote integer elements in vectors. Currently, the rest of the codegen does not support this kind of legalization. This flag will be removed when the transition is complete. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132394 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-28Refactor the type legalizer. Switch TargetLowering to a new enum - ↵Nadav Rotem
LegalizeTypeAction. This patch does not change the behavior of the type legalizer. The codegen produces the same code. This infrastructural change is needed in order to enable complex decisions for vector types (needed by the vector-select patch). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132263 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-25Rewrite fast-isel integer cast handling to handle more cases, and to be ↵Eli Friedman
simpler and more consistent. The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts). rdar://9437928 . git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132099 91177308-0d34-0410-b5e6-96231b3b80d8
