Problem 1. Each of the following assembly code snippets corresponds to the body of a C function consisting of a single control structure: a loop, if statement, or case switch. (Compiler directives, like cfi_startproc, and instructions that do not affect the semantics, like endbr64, have been removed for readability. And yes, of course the functions are all named foo.) For each one, write C code that would compile to similar assembly for the body. In other words, figure out what the code is doing and write C code to do that. You will have to figure out how many variables are being computed with, and make up names for them. (The code was compiled with -0g.) foo: a. b. C. .L3: .L2: foo: .L2: foo: .L3: .L2: movl $0, %edx movl $0, %eax jmp .L2 addl (%rdi), %edx addl $1, %eax leaq 4(%rdi), %rdi cmp1 %esi, %eax jl .L3 movl %edx, %eax ret movl (%rdi), %eax cmpl $10, %eax jle .L2 subl $10, %eax movl %eax, (%rdi) ret leal 1(%rax,%rax, 2), %eax movl %eax, (%rdi) ret movl $0, %eax jmp .L2 addl $1,…
