1. More IA32 (AKA Pentium) Instructions
inc, dec, nop, mul, imul, div, idiv, neg, & not

2. inc
dst = dst + 1
Flags affected: O, S, Z (C not affected).

3. dec
dst = dst – 1
Flags affected: O, S, Z (C not affected).

4. nop
(Actually xchg eax, eax.)
Flags affected: none.

5. mul (unsigned) edx:eax = eax * src (32-bit version) Flags affected:
O and C are 0 if edx is zero; O and C are 1 if edx is not zero
S and Z are undefined

6. imul (signed) Note: One, two, and three operand forms!
Flags affected: Varies w/ number of operands!
Note: Some accumulator-style instructions.
Note: Some yield 32- or 64-bit results for 32-bit values.

7. imul (signed) X X

8. div (unsigned) eax = edx:eax / r/m32 (32-bit version)
quotient range: 0 to
edx = edx:eax % r/m32
Flags affected: all are undefined.

9. idiv (signed) eax = edx:eax / r/m32 (32-bit version)
edx = edx:eax % r/m32
quotient range: -231 to
Flags affected: all are undefined.

10. neg

11. not
