I need help on the question that are highlighted.

BZERO JUMP COMP RSHIFT Reglster Bit Pattern 100 101 110 RO R1 R2 R3 01 10 Note: Dst Figure 4.36 A pocket pager ISA. alo 4.16 Why does sethi only load the high 22 bits of a register? It would be more useful if sethi loaded all 32 th bits of a register. What is the problem with having sethi load all 32 bits? 4.20 Hin .17 Which of the three subroutine linkage conventions Fi covered in this chapter (registers, data link area, stack) is used in Figure 4-22? 1S 4.2 .2 co 4.18 A program compiled for a SPARC ISA writes the 32-bit unsigned integer OxABCDEFO1 to a file, and reads go on O1 it back correctly. The same program compiled for a Pen- the tium ISA also works correctly. However, when the file is4 transferred between machines, the program incorrectly reads the integer from the file as OxO1EFCDAB. What is going wrong? 4.19 Refer to Figure 4-34. Show the Java assembly lan- guage instructions for the code shown in locations 0x01le - 0x0122. Use the syntax format shown in locations 0x00e3 - 0x0ef of that same figure. You will need to make use of the following Java instructions: invokespecial n (opcode 0xb7)-Invoke a method with index n into the constant pool. Note that n is a 16-bit (two-byte) index that follows the invokespecial opcode.

Explanation / Answer

answer

given by

In classify to load a 32-bit invariable (such as an address) into a roll.

This can't perhaps be done in one coaching (since all directives are 32 bits long,

there isn't room for a 32-bit standard and also an opcode and a index number)
