Question: Convert the following program into assembly. The main method should be in one module, and the factorial and power procedures in another. Do NOT use
Convert the following program into assembly. The main method should be in one module, and the factorial and power procedures in another. Do NOT use global variables (ie, a data section), unless defined globally in the pseudo-code below. Pass parameters via the stack only. Return values should use eax. Remember to preserve the register values INSIDE your functions. String intPrompt = "Please enter an integer value: " String hexPrompt = "Please enter a hex value: " String error = "Value too large for multiplication" main() { Display(intPrompt) unsigned int a = ReadInt() Display(hexPrompt) unsigned int b = ReadHex() unsigned int result = factorial(a) if ( result == -1 ) Display(error) else Display(result) unsigned int power = power( a, b ) Display(power) } unsigned int factorial( unsigned int n ) { unsigned int result = 1; while ( n > 0 ) { result *= n; if ( result > 32-bit max value ) { return -1; } --n; } return result; } unsigned int power( unsigned int base, unsigned int exp ) { if ( exp == 0 ) return base; return base * power( base, exp - 1 ); }
