implement lvalue to rvalue conversion for ocuvector components. We can now compile stuff
like this:
typedef __attribute__(( ocu_vector_type(4) )) float float4;
float4 test1(float4 V) {
return V.wzyx+V;
}
to:
_test1:
pshufd $27, %xmm0, %xmm1
addps %xmm0, %xmm1
movaps %xmm1, %xmm0
ret
and:
_test1:
mfspr r2, 256
oris r3, r2, 4096
mtspr 256, r3
li r3, lo16(LCPI1_0)
lis r4, ha16(LCPI1_0)
lvx v3, r4, r3
vperm v3, v2, v2, v3
vaddfp v2, v3, v2
mtspr 256, r2
