Troubleshooting

Troubleshooting is the process of identifying and resolving a problem, bug or error present within the software, hardware or network connectivity. It repairs and resets the computer hardware or software, when it is unresponsive or if it malfunctions. It involves locating the error, isolating the error, removing the error and bringing back the system so that it operates normally.

Stage
irmovq V,rB
irmovq $128,%rsp
icode: ifun <- M1 [PC]
icode: ifun <- M1 [0x016] = 3:0
rA:rB<- M1 [PC+1]
rA:rB<- M1 [0x017] = f:4
Fetch
valC <- M8 [PC+2]
valC <- M3 [0x18] = 128
valP<-PC+10
valP<-0x16+10 = 0x20
