Which optimization technique is machine dependent?
Peephole optimization technique is simple and an effective machine dependent technique. What is Peephole Optimization? It is a simple but effective technique for locally improving the target code.
What is machine dependent and independent code optimization?
Machine dependent code optimization is applied to object code. Machine-independent code optimization is applied to intermediate code. Involvement with Hardware. Machine dependent optimization involves CPU registers and absolute memory references.
What are the machine independent issues in code optimization?
Common Subexpression elimination :
What is machine dependent compiler features?
The allocation of the registers as well as their machine instructions’ rearrangement for the execution of the efficiency improvement process. Intermediate form. It is the form which is considered for the code optimization technique of the program which has to be compiled.
Is peephole a machine dependent optimization?
The small set of instructions or small part of code on which peephole optimization is performed is known as peephole or window. It basically works on the theory of replacement in which a part of code is replaced by shorter and faster code without change in output. Peephole is the machine dependent optimization.
What is meant by machine dependent?
‘Machine dependent’ is commonly used to describe software that can run only on a specific type of hardware, such as a specific processor. It can also be used to describe film or audio media that requires specific recording and playback equipment.
What is machine dependency?
Machine-dependent software is software that runs only on a specific computer. Applications that run on multiple computer architectures are called machine-independent, or cross-platform.
What is machine dependent and machine independent?
Which of the following is machine dependent optimization Mcq?
Explanation: Machine dependent optimizations are: Peephole optimization which includes redundant optimization, strength reduction, flow of control.
What is code Optimisation in compiler design?
Advertisements. Optimization is a program transformation technique, which tries to improve the code by making it consume less resources (i.e. CPU, Memory) and deliver high speed.
What is peephole optimization?
Peephole optimization is an optimization technique performed on a small set of compiler-generated instructions; the small set is known as the peephole or window. Peephole optimization involves changing the small set of instructions to an equivalent set that has better performance.
