[Tutorial] Meanings Of Most Popular Codes In Assembling

[AliKr96 70 iPhone 11 Pro Max 13.4.1]

* Operations are:
• ADD operand1 + operand2
• SUB operand1 - operand2
• CMP operand1 - operand2, but result not written

• CMP compare operand1 and operand2

• CMN operand1 + operand2, but result not written
• MOV moves operand1 to operand2
• STR store operand1 in operand2
• LDR load operand2 in operand1

• NOP no operation

• BX LR end the function
this is the normal meaning here are some examples:
- ADD r0,r1,r2 ; r0 = r1 + r2
- SUB r0,r6,r5 ; r0 = r6 - r5
- CMP r0,r1 ; get the greater of r1,r0 in r0
- STR r0, [r1,#-200] store r0 at r1-200
Still working on it, might take more days to continue explaining.
