The LE transformation for vec_perm has an implicit assumption

that the permutation is being used to reorder vector elements,

not to reorder bytes within those elements.
|
|
Unfortunately the result order is not the expected one for powerpc

little endian when the two first vector parameters of vec_perm are
|
|
not of type 'vector char'. This is because the numbering from the
|
|
left for BE, and numbering from the right for LE, produces a
|
|
different interpretation of what the odd and even lanes are.
