What problems do the SPEC CPU benchmarks solve that were present in earlier versions of tests like Whetstone, Dhrystone, and Linpack?

What is loop unrolling and how can it improve pipelined execution?

What is the process by which the Whetstone, Dhrystone, and Linpack tests' weaknesses are fixed by the SPEC CPU tests?

Select the logic to implement a loop using the LOOPNZ instruction. ECX = ECX – 1 if ECX > 0 and ZF=0 , jump to destination O ECX = ECX + 1 if ECX > 0 and ZF=1, jump to destination EDX = EDX - 1 if EDX < 0 or ZF=0 , jump to destination

IN ASSEMBLY CODE NOT PYTHON!!!!!!!!!!!!!!!!!!!*** ***PLEASE TEST CODE AND MAKE SURE IT WORKS PROPERLY ON REXTESTER COMPILER. https://rextester.com/l/nasm_online_compiler **** ***PLEASE PROVIDE SCREENSHOTS OF CODE INPUT/OUTPUT FROM REXTESTER . ***DONT COPY AND PASTE OTHER ANSWERS***

Compilers have trouble with designs like VLIW and superscalar. Which building is more difficult? Why?

How do SPEC tests improve CPU benchmarking over Whetstone, Dhrystone, and Linpack?

Can you tell me what the phrase "instruction pipelinelining" means? Not only should the problems with data and branches be explained, but solutions should also be given.
