How convert this pseudocode to LEGv8 ARM code? Assume g and h are in registers
X19, and X20 respectively:
if (g < h)
g=g+ h;
else
h = h * 2
Many books use SUB operator, can I use just CMP to compare g and h? Please, provide detailed explanation of each line in LEGv8

Note: we do not have jgt (>) as a conditional branch so you will have to figure out how to test a > 0 in some other way. while(a>=b) { if(c<d) c --; else if(a>0) b++; a--; }
- In 32-bit mode, aside from the stack pointer(ESP), what other register points to variables on the stack? Name at least four CPU status flags. Which flag is set when the result of an unsigned arithmetic operation is too large to fit into the destination? Which flag is set when the result of a signed arithmetic operation is either too large or too small to fit into the destination? (True/False): When a register operand size is 32 bits and the REX prefix is used, the R8D register is available for programs to use. Which flag is set when an arithmetic or logical operation generates a negative result? Which part of the CPU performs floating-point arithmetic? On a 32-bit processor, how many bits are contained in each floating-point data register? (True/False):The x86-64 instruction set is backward-compatible with the x86 instruction set. (True/False): In current 64-bit chip implementations, all 64 bits are used for addressing. (True/False):The Itanium…Convert given code to LEGv8 code:int f, g, y //global 64-bit variablesint sum (int a, int b) { // at memory address X0+1000.return (a +b)} int main (void) // at memory address X0 + 800{f=2;g=3;y= sum (f, g);return y;}Convert this code, making valid assumptions about registers and register use. Notethat brackets and global variable declarations are not affecting the addresses of the instructionsin memory.Q:Answer the following sentence with (True) or (False) and correct the false answer: 1. You can input data of size 16-bit through the fixed port. 2. In the maximum mode, the status signals S₁, S₂ and S3 are controlled by the bus controller. 3. HLDA is an output signal. 4. In 8086, when executing the instruction MOV AL, [SI+100D H] where SI-100AH, Ao=0 and BHE=1 5. When S, is 0, the TF is disabled.
