NASM Coding: Trace Tables

One way to keep track of what is happening with a program that we are working with is by creating a trace table for it: a table what keep track of the input, output, register, variable, and exit code values as the program keeps executing.

• The table will feature one row per each instruction that we run (if we have a loop, we might run the same instruction more than once, so there will be multiple rows per that instruction.)
• You may create this table using any convenient app, e.g., Microsoft Excel or Google Sheets.

Here is the trace table for the short program on slide 37:

stdin

rax

rdi

stdout

mov rax, 60

60d

mov rdi, 0

60d

0

syscall

60d

0

0

exit(0);
