Documentation error for cbranch<mode>4

[Paulo J. Matos]

Hi,

The docs state:
`cbranchmode4'
    Conditional branch instruction combined with a compare instruction. 
Operand 0 is a comparison operator. Operand 1 and operand 2 are the first 
and second operands of the comparison, respectively. Operand 3 is a 
label_ref that refers to the label to jump to.


However from my experience and after looking to other backends, operand 3 
is actually a code label and not a label_ref.

Cheers,
