assembly - What are the ESP and the EBP registers . . . - Stack Overflow Understanding the stack is very crucial in programming in assembly language as this can affect the calling conventions you will be using regardless of the type For example, even the cdecl or __stdcall is also dependent on the ESP and EBP registers, and others too in some way depend on some registers and the stack
Where do I start with assembly? - Stack Overflow Optimizing assembly language is a thing of the past Modern C C++ compilers and processors are amazingly efficient at optimizing well written C code They are well aware of all the tricks to order the instructions so they maximize parallel execution and utilize the cache most efficiently That is very hard to do by hand Most compilers also have the option to optimize for size, if that is an
assembly - What are SP (stack) and LR in ARM? - Stack Overflow I am reading definitions over and over again and I still not getting what are SP and LR in ARM? I understand PC (it shows next instruction's address), SP and LR probably are similar, but I just don
What does the and instruction do to the operands in assembly language? This should be described in the documentation for any assembler that has an and instruction It does a bit-wise Boolean "and" between two operands In other words, corresponding bits (bit n in each operand) are anded, in the Boolean operation sense, giving bit n of the result In Boolean logic, 1 and 1 = 1, but 0 and x (anything else) = 0 Thus, 10111010 and 01101011 results in 00101010 If
