/* Let <op>L be the lower part of operand <op> and <op>U be the upper part.
The P[UL][UL].PS instruction always specifies the upper part of the
result first, so the instruction is:
P<aUL><bUL>.PS %0,<aop>,<bop>
where 0U == <aop><aUL> and 0L == <bop><bUL>.
GCC's vector indices are specified in memory order, which means
that vector element 0 is the lower part (L) on little-endian targets
and the upper part (U) on big-endian targets. vec_concat likewise
concatenates in memory order, which means that operand 3 (being
0 or 1) selects part of operand 1 and operand 4 (being 2 or 3)
selects part of operand 2.
Let:
I3 = INTVAL (operands[3])
I4 = INTVAL (operands[4]) - 2
Taking the two endiannesses in turn:
Little-endian:
The semantics of the RTL pattern are:
{ 0L, 0U } = { X[I3], X[I4 + 2] }, where X = { 1L, 1U, 2L, 2U }
so: 0L = { 1L, 1U }[I3] (= <bop><bUL>)
0U = { 2L, 2U }[I4] (= <aop><aUL>)
<aop> = 2, <aUL> = I4 ? U : L
<bop> = 1, <bUL> = I3 ? U : L
[LL] !I4 && !I3 [UL] I4 && !I3
[LU] !I4 && I3 [UU] I4 && I3
Big-endian:
The semantics of the RTL pattern are:
{ 0U, 0L } = { X[I3], X[I4 + 2] }, where X = { 1U, 1L, 2U, 2L }
so: 0U = { 1U, 1L }[I3] (= <aop><aUL>)
0L = { 2U, 2L }[I4] (= <bop><bUL>)
<aop> = 1, <aUL> = I3 ? L : U
<bop> = 2, <bUL> = I4 ? L : U
[UU] !I3 && !I4 [UL] !I3 && I4
