For little endian, we need to make some straightforward adjustments in the code expansions for scalar_to_vector and vector_extract of v2f64. First, scalar_to_vector must place the scalar into vector element zero. However, our implementation of SUBREG_TO_REG will place it into big-element vector element zero (high-order bits), and for little endian we need it in the low-order bits. The LE implementation splats the high-order doubleword into the low-order doubleword. Second, the meaning of (vector_extract x, 0) and (vector_extract x, 1) must be reversed for similar reasons. A new test is added that tests code generation for insertelement and extractelement for both element 0 and element 1. It is disabled in this patch but enabled in patch 4/4, for reasons stated in the test. llvm-svn: 223788 |
