implementation of the standard c library function strcpy in assembly language

Consider the textbook’s implementation of the standard C library function strcpy in assembly language. Implement memset, strlen, strchr, strcat, and strcmp.

  • Use $a0 through $a3 as necessary for the standard C library’s arguments to each function.
  • Return in $v0.
  • Do *not* write a main program. You will be given a testing program soon.
  • It is fine if a lot of your functions look a lot like each other. In fact, that’s a good sign.
  • Don’t worry about overruns or exception cases.

EXTRA CREDIT (10 points): Implement strstr. Don’t try this until you’ve finished the others – strstr is a lot more annoying to implement.
