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
