So I took a look at the x86 assembly language; All the commands are pretty clear but: I don\'t see anything that can actually trigger something in the computer like: Access RAM and not only CPU regist

I\'ve come to learn that you cannot push a byte directly onto the Intel Pentium\'s stack, can anyone explain this to me please?
It seems that the following is a common method given in many tutorials on switching a processor from 16-bit to 32-bit:
I am doing some performance critical work in C++, and we are currently using integer calculations for problems that are inherently floating point because "its faster". This causes a whole lo
I have a 128-bit unsigned integer A and a 64-bit unsigned integer B. What\'s the fastest way to calculate A % B - that is the (64-bit) remainder from dividing A by B?
Consider: popl%ebp It seems the %ebp开发者_JAVA百科 is unnecessary, because the pop operation of stack doesn\'t need a parameter.
What is the shortest way to fetch a value from m开发者_开发知识库emory in X86 Assembler?You mean other than mov register, [address]?There is no workaround in assembler haw to do that. All assembler in
0x004012d0 <main+0>:push%ebp 0x004012d1 <main+1>:mov%esp,%ebp 0x004012d3 <main+3>:sub$0x28,%esp
I was reading over this question and wondered if the accepted answer might also be a way to determine the architecture. For instance, in asm could I push a WORD onto the stack and then 开发者_如何学编
