This pull request adds the capability to truncate operations with
VectorTypeoperands in LLVM IR.If the operands of an operation to be truncated is a
VectorTypeof the floating-point type to truncate, the operation is turned into multiple invocations of the corresponding scalar truncated operation.VectorTypeoperands and the return type are assumed to have the same number of elements: forVectorTypevariablesa,b,reswhereres = a vec_op b, it is assumed thatres[i] = a[i] scalar_op b[i]. If there are scalar operands, it is broadcast to all the scalar truncated operations.Intrinsic functions of that follow this rule are similarly supported. However, vector reduction or predication intrinsics are not supported. Function/operations with
VectorTypeoperands of different sizes are not supported either.
