Asm-1. Disassemble
Here’s some assembly produced by compiling a C program. QUESTION ASM-1A.How many arguments might this function have? Circleall that apply. 1. 0 2. 1 3. 2 4. 3 or more QUESTION ASM-1B.What might this function return? Circle all thatapply. 1. 0 2. 1 3. −1.
4) Its first argument, whatever that argument is.
5) A square number other than 0 or 1.
6) None of.
Asm-10. Machine Programming
Intel really messed up this time. They’ve released a processor, theFartium Core Trio, where every instruction is broken exceptthe oneson this list. (In case you forgot, xchgqswaps two values—here, the values in tworegisters—without modifying condition codes.) “So what if it’s buggy,” says Andy Grove; “it can still run programs.”For instance, he arg.
ASM-2. Assembly
Here is some x86 assembly code. QUESTION ASM-2A. Write valid C code that could have compiled intothis assembly (i.e., write a C definition of function f), given theglobal variable declarations “extern unsigned a, b;.” Your C codeshould compile without warnings. REMINDER:You are not permitted torun a C compiler, except for the C compiler that is you.
ASM-3. Assembly and Data Structures
For each code sample below, indicate the most likely type of the databeing accessed. (If multiple types are equally likely, just pick one.) QUESTION ASM-3A. movzbl %al, %eax QUESTION ASM-3B. movl -28(%rbp), %edx QUESTION ASM-3C. movsbl -32(%rbp), %eax QUESTION ASM-3D. movzwl -30(%rbp), %eax For each code sample below, indicate the most likely data .
Asm-4. Assembly Language
The next four questions pertain to the following four code samples. Now answer the following questions. Pick the most likely sample; youwill use each sample exactly once. QUESTION ASM-4A.Which sample contains a for loop? QUESTION ASM-4B.Which sample contains a switch statement? QUESTION ASM-4C.Which sample contains only an if/else construct? QUESTI.
ASM-5. Calling Conventions: 6186
University Professor Helen Vendler is designing a poetic new processor,the 6186. Can you reverse-engineer some aspects of the 6186’s callingconvention from its assembly? Here’s a function: And here’s that function compiled into 6186 instructions. 6186 assembly syntax is based on x86-64 assembly, and like the x86-64,6186 registers are 64 bits wide. .
ASM-6. Data Structure Assembly
Here are four assembly functions, f1 through f4. QUESTION ASM-6A.Each function returns a value loaded from some datastructure. Which function uses which data structure?.
1) Array.
2) Array of pointers to arrays.
3) Linked list.
4) Binary tree QUESTION ASM-6B.The array data structure is an array of type T.Considering the code for the function that manip.
Asm-7. Where’s Waldo?
In the following questions, we give you C code and a portion of theassembly generated by some compiler for that code. (Sometimes we blankout a part of the assembly.) The C code contains a variable, constant,or function called waldo, and a point in the assembly is marked withasterisks ***. Your job is to find Waldo: write an assemblyexpression or co.
Asm-9. Disassembly II
The questions in this section concern a function called ensmallen,which has the following assembly. QUESTION ASM-9A.How many arguments is this function likely to take?Give line numbers that helped you determine an answer. QUESTION ASM-9B.Are the argument(s) pointers? Give line numbersthat helped you determine an answer. QUESTION ASM-9C.What type(s).

How to construct a procedure in assembly language?
To construct a procedure
It’s ideal to make all your logics within the procedure body. Preferred is a procedure with one entrance and one exit. Since in assembly language programming
A procedure name is directly represented by a memory address
As well as any labels.
Should I use more instructions if I'm taking assembly language programming?
If you are taking an Assembly Language Programming class
This could be a supplemental reading for studies. The first two rules are general. If you can use less
don’t use more.
1) Using less instructions The example is to add var1 to EAX. This is correct with MOV and ADD:
2. Using an instruction with less bytes
What is assembly programming language?
Assembly is a low-level programming language used to directly translate instructions into the computer’s machine code in a more human-readable way. Similar to machine code
Each instruction begins with an opcode and then references memory locations or data types to operate on.
What are some basic practices in assembly language programming?
A discussion on some basic practices highly recommended in Assembly Language Programming. 1. Using less instructions 2. Using an instruction with less bytes 3. Implementing with memory variables 4. If you can use registers, don’t use memory 5. Using atomic instructions 6. Memory representations 7. A code error hidden by little-endian 8.
What is assembly language?
With arguments received from within a procedure Assembly language is a low-level programming language for niche platforms such as IoTs, device drivers, and embedded systems. Usually, it’s the sort of language that Computer Science students should cover in their coursework and rarely use in their future jobs.
