Assume we are on a x86, 64-bit Linux OS and we have the following code below. Assume the string hello is stored at the memory address 0x800020. Describe the values of the registers RAX, RBX RCX, RDX, RDI, and RSI immediately before jumping to the function foo() (how are these registers setup per the Linux calling convention). If the register is not used for this operation, set it to 0.

unsigned int foo (unsigned int a , char str ) {

return 65;

}

int main ( ) {

int b = foo ( 3 , hello) ;

return b ;

}

Here are the Linux calling conventions
