Inline Assembler for PPC

["Martin Payne" <martin at microcosm dot co dot uk>]

I am trying to do some very simple inline assembler with GCC, compiling on the Mac (MACOSX).

All I would like to do is to store the value of a C function I have just called into a C variable called "i".

So instead of doing:

i = myfunction();

I want to do something like this:

myfunction();
stw r3, i

(I know the value of the function is stored into the r3 register.)

It might look odd but I have my reasons for doing this. However, for everything I try with the keyword "asm" for inline assembler, it doesn't compile.

All I want to do is put the value in register r3 into my C variable, i.

Any ideas?
