* Allow to fold vector load if there is more than one bitcast, so in the case:Jakub Staszak2012-10-29
| | | | | | | | | | | | | | | | | | | | %0 = load <8 x i16>* %dest %1 = shufflevector <8 x i16> %0, <8 x i16> %in, <8 x i32> < i32 0, i32 1, i32 2, i32 3, i32 13, i32 undef, i32 14, i32 14> store <8 x i16> %1, <8 x i16>* %dest We get: vmovlpd (%eax), %xmm0, %xmm0 instead of: vmovaps (%eax), %xmm1 vmovsd %xmm1, %xmm0, %xmm0 No extra test-case is added. I just fixed the existing one (also it uses FileCheck now). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166971 91177308-0d34-0410-b5e6-96231b3b80d8

* change selectiondag to add the sign extended versions of immediate operandsChris Lattner2009-09-08
| | | | | | | | | to instructions instead of zero extended ones. This makes the asmprinter print signed values more consistently. This apparently only really affects the X86 backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81265 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | PR2957 ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes as the shuffle mask. A value of -1 represents UNDEF. In addition to eliminating the creation of illegal BUILD_VECTORS just to represent shuffle masks, we are better about canonicalizing the shuffle mask, resulting in substantially better code for some classes of shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70225 91177308-0d34-0410-b5e6-96231b3b80d8
