[Dev-C++] How to implement ASM instructions?

[Klakier <kal...@in...>]

Hi all

    I have just changed Visual C++ to great DEV-C++, and I have small
problem.
When I wanted to join assembler code to my CPP file I must type:

__asm
{
    mov 0x077, dx
    in al, dx
    and al, 0xE0
}

How can I do the same in DEV-C++?

Thanks for help

Hi!

There are several ways to implement assembler in GCC (Dev-C++).
1:	learn AT&T assembler
2:	use Intel to AT&T converter
3:	use external assembler linker, that produces gcc compatible
object files and then in your C source declare "external asm_foo()" and
in linking time, add asm_foo.o in to the process

I'd prefer third one, but I must seek out an assembler compiler, that
takes Intel code and produces gcc compatible object files. I think it
would be nasm [further investigation required].

__asm("put your asm instructions here");

You should read the GCC manual.
