\n Learning Goal: <\/b>I’m working on a programming writing question and need the explanation and answer to help me learn.<\/p>\n

Be sure to modify the variables with YOUR First and Last names!<\/strong><\/p>\n

This is a take-home Lab. You should<\/i> be able to do this with your RaspberryPi as discussed. However, you may also use the IoT Lab in ERB to connect to your Pi and do this assignment.<\/p>\n

This is an individual assignment.<\/p>\n

You will be required to provide READABLE<\/strong> screen captures in a PDF file.<\/p>\n

You will be using the gdb debugger to pause your program at specific places in your program. We have discussed how to do this in class multiple times.<\/p>\n

You will use my c code below to create a function in ARM assembly that will concatenate your first name and last name into a single string based on the definition of the external function \u00e2\u20ac\u02dcstrCat\u00e2\u20ac\u2122.<\/p>\n

\/\/ CSE 2312 Computer Org and Assembly Language Programming

\/\/ strings concatenate

\/\/ YOUR NAME




#include <stdlib.h> \/\/ EXIT_ macro

#include <stdio.h> \/\/ printf

#include <inttypes.h> \/\/ PRI macro

#include <stdint.h> \/\/ C99 uintX_t and intX_t types




extern void strCat(const char first[], const char last[]);




int main(void)

{

char last[] = \"Lastname\";

char str[] = \"Hello World!\";

char first[30] = \"Firstname \"; \/\/ with a \u00e2\u20ac\u02dcspace\u00e2\u20ac\u2122 at the end<\/strong>

strCat(first, last);

printf(\"Full Name = %s\\n\", first);

return EXIT_SUCCESS;

}<\/pre>\n
    \n
  1. You will place a breakpoint where strCat is called.<\/li>\n
  2. You will \u00e2\u20ac\u02dcstep\u00e2\u20ac\u2122 into the assembly function.<\/li>\n
  3. You will need to list your assembly function to find the BX LR line.<\/li>\n
  4. You will place a breakpoint at the BX LR line.<\/li>\n
  5. DO NOT Continue Yet!<\/li>\n
  6. You must use the debugger to display the memory location of the string \u00e2\u20ac\u0153first\u00e2\u20ac\ufffd<\/li>\n
  7. the command is:x\/64cb $r#<\/li>\n
  8. Replace the # with the correct register number, note the first address printed, you will need this later.<\/li>\n
  9. Now \u00e2\u20ac\u02dccontinue\u00e2\u20ac\u2122 the program.<\/li>\n
  10. When it pauses at BX LR, you will need to display the memory as before, but replace \u00e2\u20ac\u02dc$r#\u00e2\u20ac\u2122 with the address noted earlier.<\/li>\n
  11. Now \u00e2\u20ac\u02dccontinue\u00e2\u20ac\u2122 again.<\/li>\n
  12. The program should now be complete and c should have printed the full name.<\/li>\n
  13. Take a screenshot of the window showing all the debugger output.<\/li>\n
  14. You may have to repeat the process flawlessly to get all the data on one screen<\/strong><\/li>\n
  15. You will also provide a screenshot of the assembly code. Your name must be in a comment at the top of the file.<\/strong><\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
