Handle constantpacked vectors with constantexpr elements. This fixes CodeGen/Generic/vector-constantexpr.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27241 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-28When building a VVECTOR_SHUFFLE node from extract_element operations, makeChris Lattner
sure to build it as SHUFFLE(X, undef, mask), not SHUFFLE(X, X, mask). The later is not canonical form, and prevents the PPC splat pattern from matching. For a particular splat, we go from generating this: li r10, lo16(LCPI1_0) lis r11, ha16(LCPI1_0) lvx v3, r11, r10 vperm v3, v2, v2, v3 to generating: vspltw v3, v2, 3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27236 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-27SelectionDAGISel can now natively handle Switch instructions, in the sameNate Begeman
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary search tree of basic blocks. The new approach has several advantages: it is faster, it generates significantly smaller code in many cases, and it paves the way for implementing dense switch tables as a jump table by handling switches directly in the instruction selector. This functionality is currently only enabled on x86, but should be safe for every target. In anticipation of making it the default, the cfg is now properly updated in the x86, ppc, and sparc select lowering code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27156 91177308-0d34-0410-b5e6-96231b3b80d8
