Question about quad-register
Hi All,
If the target supports quad-register R0:R1:R2:R3 (Rn is 32-bit
register), is it possible mapping quad-register
to v4i32 so that the following example work?
typedef int v4si __attribute__ ((vector_size (16)));
void foo(v4si i) {
v4si j = i;
}
I don't know how to write CallingConv.td to represent the concept of
occupying quad-register R0:R1:R2:R3
once seeing
