Signature _______________________ Name_________________ cs30x____ Student ID ______________________ Score: Quiz 2 CSE 30 Winter 2007 #1. a) Write the SPARC assembly instructions to define the following global variables in the data segment: char CSI[] = "Las Vegas"; double delight = 4.11; #2. What is the value ( in hex ) of %o1 after each set of instructions: a) set 0xDEADBEEF, %o1 sra %o1, 16, %o1 Value in %o1 at this point is 0x ______________________________________________ b) set 0xDEADBEEF, %o1 set 0x6B6B6B6B, %o2 xor %o1, %o2, %o1 Value in %o1 at this point is 0x ______________________________________________ c) set 0xDEADBEEF, %o1 set 0x6B6B6B6B, %o2 and %o1, %o2, %o1 Value in %o1 at this point is 0x ______________________________________________ #3.

Unformatted text preview: Assume you correctly set this breakpoint and performed a run with correct command line arguments. State how to print the value of the 3 rd argument passed to displayDiamond(): (over) #4. Write the equivalent unoptimized SPARC assembly language instructions to perform the following C code fragment. Use the loop construct specified in class/Notes. C SPARC assembly /* x is mapped to %l0 */ /* a is mapped to %l1 */ for ( a = 4; a < 29; ++a ) { x = 5678 + a; } #5. Write the equivalent unoptimized SPARC assembly language instructions to perform the following C code fragment. C SPARC assembly x = x % 8309; /* x is mapped to %l2 */ Now optimize your answer to eliminate any delay slots : Optimized version of above SPARC assembly...
