assembly inline C for NIOS II

Altera_Forum · ‎05-19-2012

Hi all,

I am new for NIOS II application develoment.

And I need to embed a few lines of assembly

in my C code. like:

# include "system.h"

void main()

{

C code 1;

_asm_("assembly 1");

C code 2;

_asm_("assembly 2");

C code 3;

}

My question is if the Nios II SBT will automatically

save the previous operation results (from registers

or somewhere else) before execute the assembly.

As we know it does when the system handle interrupt.

But how about this sutiation? Thanks in advance if you can help.:)

You need to read up how gcc does inline assembly.
