Question

Short Answer 1. A 2. 3. Using 4. is where a function's local variables are stored define the process of low-level procedure implementation the caller is responsible for dleaning up stack memory registers are considered to be volatile because they will Ikely be used and overwritten in a function 5. The 6. The 7, 8. instruction implicitly pushes the subsequent instruction on the stack. register points to the most recent item pushed on the stack. and and code are common lines of code upon entry to and exit from a tunction. nstructions implicitly add and subtract trom the stack pointer register as values are moved on and off the stack. 9. n 32-bit stdcall, the number of bytes to remove from the stack are stated with the instruction register is typically used as the retum register. is a 32-bit calling convention that uses registers to pass values if possible. 10. The 12. The x86 64 calling conventionis) attempt to pass some or all parameters via instead of the stack. 13. Microsoft x64 reserves bytes of shadow space, whie AMD64 preserves bytes of red-zone space. 14. 15. An functions are functions that make no calls. defines lowlevel (i.e., machine level) interfacing requirements for software

Explanation / Answer

1. A stack is where a function's local variables are stored.

2. ASSEMBLY language

3. using CDECL, the caller is responsible for cleaning up stack memory

4. Scratch registers (R0, R1, R2 and R3) are considered volatile. More specifically, The registers RAX, RCX, RDX, R8, R9, R10, R11 are considered volatile in 64-bit configuration.

5. The lcall implicitly pushes the next instruction on stack

6. Stack Pointer Register always points to the top of the stack.

7. ENTRY and RET

8. PUSH and POP

9. RET

10. EAX register is used to store the return values
