Question

I remember back in the day with the old borland DOS compiler you could do something like this:

A good start would be reading this article which talk about inline assembly in C/C++:

http://www.codeproject.com/KB/cpp/edujini_inline_asm.aspx

Example from the article:

#include 


int main() {
    /* Add 10 and 20 and store result into register %eax */
    __asm__ ( "movl $10, %eax;"
                "movl $20, %ebx;"
                "addl %ebx, %eax;"
    );

    /* Subtract 20 from 10 and store result into register %eax */
    __asm__ ( "movl $10, %eax;"
                    "movl $20, %ebx;"
                    "subl %ebx, %eax;"
    );

    /* Multiply 10 and 20 and store result into register %eax */
    __asm__ ( "movl $10, %eax;"
                    "movl $20, %ebx;"
                    "imull %ebx, %eax;"
    );

    return 0 ;
}
