Topics
| Topic | Question/Topic Description | Student |
|---|---|---|
| x86 Registers | What are the names and sizes of all of the x86_64 registers? | |
| Aarch64 Registers | What are the names and sizes of all of the Aarch64 registers? | |
| NASM Syntax | What is NASM, and what are the basic rules of NASM syntax? | |
| GNU x86_64 gas Syntax | What are the basic rules of GNU Assembler (gas) syntax for x86_64 platforms? | |
| GNU aarch64 Syntax | What are the basic rules of GNU Assembler (gas) syntax for aarch64 platforms? | |
| Argument storage on x86_64 | When a function/procedure is called on an x86_64 Linux system, where are the arguments stored? | |
| Argument storage on aarch64 | When a function/procedure is called on an aarch64 system, where are the arguments stored? | |
| System call numbers on x86_64 | What are the system call numbers on an x86_64 Linux system? | |
| System call numbers on aarch64 | What are the system call numbers on an aarch64 Linux system? | |
| PLT | In an ELF file, what is a PLT and how is it used? | |
| Static and dynamic linking | What are the differences between static and dynamic linking? Advantages of each? | |
| Copy-on-write | What is copy-on-write (when referring to memory in a Linux system)? When is it used? | |
| Assembling using gas | How do you use the GNU assembler (gas) to compile an assembly-language program? | |
| Single-stepping with gdb | How do you execute a program one instruction at a time (single-stepping) using the GNU debugger (gdb)? | |
| Dividing on x86_64 and aarch64 | How do the division instructions work on x86_64 and aarch64? How are they different? | |
| The Mysterious XOR | x86 and x86_64 code often contains instructions that XOR a register with itself (e.g., xor %eax,%eax). What does this do and why is it used? |
