Re: Caaling assembly routine in c

Hi All,

I am working on MIPS architecture and I am
compiling my project using GHS tool chain.

I want to call a assembly routine into c function.
My code is like that:

.globl asm
.ent asm

asm:
----
----
.end asm

I am calling this routine in c function like that:

extern void asm(void);

void foo()
{
  asm();
}

On compiling, error message comes that symbol asm unresolved.

Could any one tell that how I can do it for GHS.

Regards,
Sachin


Hi,

There is not much said about assemby routines from C its more implementation specific stuff.
However this is what the C89 standard has to say -

A.6.5.10 The asm keyword

   The asm keyword may be used to insert assembly-language code
directly into the translator output.  The most common implementation
is via a statement of the form

         asm (  character-string-literal );

So make sure you pass a character-string-literal as a param, not a void !
