extract_vector_elt type mismatch?

I think it's a pretty common RISC situation. I notice you deprecated
the mismatching types in r255359, but I don't really see an
alternative after type-legalization with the current nodes. I suppose
we could add ISD::EXTRACT_SEXT_VECTOR_ELEMENT and
ISD::EXTRACT_ZEXT_VECTOR_ELEMENT or something.

extract_vector_elt type mismatch?
Hi there,
I'm trying to map extract_vector_elt use the following pattern in tbl file.
Def : Pat <(i64 (extractelt v2i32:$src, 0)), (i64 (SRLIMM GPR:$src, 32))>;
But the tblgen shows :
Type inference contradiction found , forcing v2i32 to have a vector element
of type i64
But the manual says this instruction allows return type to be larger than
element type.
Anyone can show me any
