Chad Rosier 7f35455708 When performing a truncating store, it's possible to rearrange the data ... in-register, such that we can use a single vector store rather then a series of scalar stores. For func_4_8 the generated code vldr d16, LCPI0_0 vmov d17, r0, r1 vadd.i16 d16, d17, d16 vmov.u16 r0, d16[3] strb r0, [r2, #3] vmov.u16 r0, d16[2] strb r0, [r2, #2] vmov.u16 r0, d16[1] strb r0, [r2, #1] vmov.u16 r0, d16[0] strb r0, [r2] bx lr becomes vldr d16, LCPI0_0 vmov d17, r0, r1 vadd.i16 d16, d17, d16 vuzp.8 d16, d17 vst1.32 {d16[0]}, [r2, :32] bx lr I'm not fond of how this combine pessimizes 2012-03-13-DAGCombineBug.ll, but I couldn't think of a way to judiciously apply this combine. This ldrh r0, [r0, #4] strh r0, [r1] becomes vldr d16, [r0] vmov.u16 r0, d16[2] vmov.32 d16[0], r0 vuzp.16 d16, d17 vst1.32 {d16[0]}, [r1, :32] PR11158 rdar://10703339 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154340 91177308-0d34-0410-b5e6-96231b3b80d8		2012-04-09 20:32:02 +00:00

Generic	Add VSELECT to LegalizeVectorTypes::ScalariseVectorResult. Previously it would crash if it encountered a 1 element VSELECT. Solution is slightly more complicated than just creating a SELET as we have to mask or sign extend the vector condition if it had different boolean contents from the scalar condition.
