/*
 * You are doasm, holding in your hand a Prog* with p->as set to, say, ACRC32,
 * and p->from and p->to as operands (Adr*).  The linker scans optab to find
 * the entry with the given p->as and then looks through the ytable for that
 * instruction (the second field in the optab struct) for a line whose first
 * two values match the Ytypes of the p->from and p->to operands.  The function
 * oclass in span.c computes the specific Ytype of an operand and then the set
 * of more general Ytypes that it satisfies is implied by the ycover table, set
 * up in instinit.  For example, oclass distinguishes the constants 0 and 1
 * from the more general 8-bit constants, but instinit says
 *
 *        ycover[Yi0*Ymax + Ys32] = 1;
 *        ycover[Yi1*Ymax + Ys32] = 1;
 *        ycover[Yi8*Ymax + Ys32] = 1;
 *
 * which means that Yi0, Yi1, and Yi8 all count as Ys32 (signed 32)
 * if that's what an instruction can handle.
 *
 * In parallel with the scan through the ytable for the appropriate line, there
 * is a z pointer that starts out pointing at the strange magic byte list in
 * the Optab struct.  With each step past a non-matching ytable line, z
 * advances by the 4th entry in the line.  When a matching line is found, that
 * z pointer has the extra data to use in laying down the instruction bytes.
 * The actual bytes laid down are a function of the 3rd entry in the line (that
 * is, the Ztype) and the z bytes.
 *
 * For example, let's look at AADDL.  The optab line says:
 *        { AADDL,        yaddl,  Px, 0x83,(00),0x05,0x81,(00),0x01,0x03 },
 *
 * and yaddl says
 *        uchar   yaddl[] =
 *        {
 *                Yi8,    Yml,    Zibo_m, 2,
 *                Yi32,   Yax,    Zil_,   1,
 *                Yi32,   Yml,    Zilo_m, 2,
 *                Yrl,    Yml,    Zr_m,   1,
 *                Yml,    Yrl,    Zm_r,   1,
 *                0
 *        };
 *
 * so there are 5 possible types of ADDL instruction that can be laid down, and
 * possible states used to lay them down (Ztype and z pointer, assuming z
 * points at {0x83,(00),0x05,0x81,(00),0x01,0x03}) are:
 *
 *        Yi8, Yml -> Zibo_m, z (0x83, 00)
 *        Yi32, Yax -> Zil_, z+2 (0x05)
 *        Yi32, Yml -> Zilo_m, z+2+1 (0x81, 0x00)
 *        Yrl, Yml -> Zr_m, z+2+1+2 (0x01)
 *        Yml, Yrl -> Zm_r, z+2+1+2+1 (0x03)
 *
 * The Pconstant in the optab line controls the prefix bytes to emit.  That's
 * relatively straightforward as this program goes.
 *
 * The switch on t[2] in doasm implements the various Z cases.  Zibo_m, for
 * example, is an opcode byte (z[0]) then an asmando (which is some kind of
 * encoded addressing mode for the Yml arg), and then a single immediate byte.
 * Zilo_m is the same but a long (32-bit) immediate.
