Help in C language

A certain function is declared: unsigned foo(unsigned x, unsigned y); It compiles to the following assembly code:

mov1 $0,% eax .L2: test1 \%esi, \%esi je .L4 add1 \%edi, \%eax subl $1,% esi jmp .L2 .L4: ret Recall that the first argument is passed in \%rdi, the second in \%rsi, and the return value is passed in \% rax (or in this case, since it is a four-byte integer, \%eax). The C code has the following general structure: a. Fill in the blanks with code that will result in the given assembly code (when compiled with - Og and ignoring endbr64. b.
