Hey devs, From ISDOpcodes.h... /// BUILDVECTOR(ELT0, ELT1, ELT2, ELT3,...) - Return a fixed-width vector /// with the specified, possibly variable, elements.

Must the operand types always be the same? Or could we see a BUILDVECTOR with mixed integer types? E.g.: BUILDVECTOR(i32, i32, i64, i32) Thanks, Cam
