// Basic case of ambiguity for inc.

inc dword ptr [eax]
inc word ptr [eax]
inc byte ptr [eax]
// CHECK-NOT: error:

// Other ambiguous instructions.  Anything that doesn't take a register,
// basically.

dec [eax]
// CHECK: error: ambiguous operand size for instruction 'dec'
mov [eax], 1
// CHECK: error: ambiguous operand size for instruction 'mov'
and [eax], 0
// CHECK: error: ambiguous operand size for instruction 'and'
or [eax], 1
// CHECK: error: ambiguous operand size for instruction 'or'
add [eax], 1
// CHECK: error: ambiguous operand size for instruction 'add'
sub [eax], 1
// CHECK: error: ambiguous operand size for instruction 'sub'

// gas assumes these instructions are pointer-sized by default, and we follow
// suit.
