I want make simple assembly code for some thing like this a^6+6a^2+2a and range of a is between -3 to 3. I tried but it is not working properly. As this is my first assembly program that I am going to try, I want some help with it.
I found this example online but i dont want this kind of complicated stuff. I just want to start of with simple programing by using function like call .mul, add, sub thatz all.
I am currently looking into an os on developed on an x86 platformwhich contains certain assembly code written in .s files(NASM- compatible ) instead of using C I was wondering why C could not be used to do low level stuff instead? Do anyone have any idea or could enligthen me?Appreciate any help... (0 Replies)

Hi guys,
Assembly language is a low level language designed in 1950's, both system and application programs were written in assembly at that time. There is no question of assembly being very effecient compared to the other high level languages. But it is very cumbersome to write programs in... (9 Replies)

stack
STACK(9) BSD Kernel Developer's Manual STACK(9)NAME
STACK -- stack macros
SYNOPSIS
#include <sys/param.h>
type
STACK_ALLOC(sp, size);
type
STACK_MAX(sp, size);
type
STACK_ALIGN(sp, bytes);
type
STACK_GROW(sp, size);
type
STACK_SHRINK(sp, size);
DESCRIPTION
A stack is an area of memory with a fixed origin but with a variable size. A stack pointer points to the most recently referenced location
on the stack. Initially, when the stack has a size of zero, the stack pointer points to the origin of the stack. When data items are added
to the stack, the stack pointer moves away from the origin.
The STACK_ALLOC() macro returns a pointer to allocated stack space of some size. Given the returned pointer sp and size, STACK_MAX() returns
the maximum stack address of the allocated stack space. The STACK_ALIGN() macro can be used to align the stack pointer sp by the specified
amount of bytes.
Two basic operations are common to all stacks: a data item is added (``push'') to the location pointed by sp or a data item is removed
(``pop'') from the stack. The stack pointer must be subsequently adjusted by the size of the data item. The STACK_GROW() and STACK_SHRINK()
macros adjust the stack pointer sp by given size.
A stack may grow either up or down. The described macros take this into account by using the __MACHINE_STACK_GROWS_UP preprocessor define.
