What is a good way to compare register values in a PIC assembly

[Dwnld_pwm]

Hello everyone.

I'm using a PIC16F887 with the PICkit2.
There doesn't seem to be a compare instruction so I'm wondering how one would go about comparing the values of two registers.

For example let's say Register REG1 has a value b'00100010' and REG2 has b'000000000' but the value of REG2 increases by 1 every loop iteration. I want the loop to stop when REG2 = REG1.
Is there a way of comparing them?

It's easy in C, but how do I implement it in assembly?
I'll leave a mixture of Assembly and C for reference.

Cheers,

MOVLW b'00100010'
MOVWF REG1

CLRF REG2

Loop:
INCF REG2
;(if REG2 == REG1){
goto stop
}
else{
goto Loop

Think I've just figured it out, here's the solution for whoever stumbles upon this in the future


MOVLW b'00100010'
MOVWF REG1

CLRF REG2

Loop:
INCF REG2, F
MOVFW REG2
SUBWF REG1, W
BTFSS STATUS, Z ;If REG1 = REG2 then REG1 - REG2 = 0 setting Z = 1
goto Loop
goto Stop

Also the logic instructions can be used in different ways to compare. notably the AND, XOR AND IOR.
