Hey devs,
From ISDOpcodes.h...
/// BUILD_VECTOR(ELT0, ELT1, ELT2, ELT3,...) - Return a fixed-width vector /// with the specified, possibly variable, elements. The number of elements /// is required to be a power of two. The types of the operands must all be /// the same and must match the vector element type, except that integer types /// are allowed to be larger than the element type, in which case the operands /// are implicitly truncated. BUILD_VECTOR,
Must the operand types always be the same? Or could we see a BUILD_VECTOR with mixed integer types? E.g.:
BUILD_VECTOR(i32, i32, i64, i32)
Thanks, Cam
