Emitting the temp and assignment to it into the IR seems spurious --
is there a reason something like this doesn't work:?
ir_rvalue *base_expr = ir->operands[0];
ir->operation = ir_triop_bfi;
ir->operands[0] = new(ir) ir_expression(ir_binop_bfm, ir-type,
swizzle_xxxx(ir->operands[3]),
swizzle_xxxx(ir->operands[2]));
/* ir->operands[1] is still the value to insert. */
ir->operands[2] = base_expr;
ir->operands[3] = NULL;
I might have missed something :)
