Opcode map field used...	For operand type...	Unit
src2	xsp	.S1, .S2
dst	dp

Description	The single-precision value in src2 is converted to a double-precision value and
	placed in dst.
Execution	if (cond)	dp(src2) → dst
	else	nop

Notes:

1)If src2 is SNaN, NaN_out is placed in dst and the INVAL and NAN2 bits are set.

2)If src2 is QNaN, NaN_out is placed in dst and the NAN2 bit is set.

3)If src2 is a signed denormalized number, signed 0 is placed in dst and the INEX and DEN2 bits are set.

4)If src2 is signed infinity, INFO bit is set.

5)No overflow or underflow can occur.
