Compare Word

[Bully@Wiiplaza]

How exactly does the cmpw instruction work? I keep being confused about it... here´s how it works with intel 80386 assembler logic:

#Calculate r11 minus r12 and use that result for the branch#
cmpw r11, r12

# Jump if the result is positive ("r11 is bigger")#
bgt JUMP

# Jump if the result is negative ("r12 is bigger")#
blt JUMP

Am I right or dead wrong? ???

That's pretty much it.  On a high level, cmpw just asks "is the first register greater than, less than, or equal to the second register?"

On a lower level, it's subtracting the second register from the first (r11 - r12), and then sets the condition register fields based on the result.  If the result is positive, the greater-than bit is set.  If the result is negative, the less-than bit is set.  If the result is 0, the equal bit is set.

Branches are then taken or not taken based on the condition register field.  A bgt branch is taken only if the greater than bit is set.  A ble branch is taken if either the less-than or the equal bit are set.

Since you do not specify a condition register field, and you're using integer registers, it will default to using the cr0 field.
