[LLVMdev] CompositeIndices
Does anyone know exactly what ComposerIndices in Target.td is all about?
I see just one place where it's used in X86 but it's not clear from the
comments in Target.td and it's one usage, exactly what this feature is
about.

[LLVMdev] Simpler subreg ops in machine code IR

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
