Hi,
I have a question about inline assembly code. If I do something like
register int x;
register int y;
x = y = 0;
__asm__ __volatile__ (
...manipulate x, y and other stuff for a while....
: "+r"(x), "+r"(y)
);
to set up two variables for manipulation within the assembly code things
go wrong. x and y get coalesced during optimisation and are not treated
as separate working values. This is exactly what one would expect from
the documentation. What I can't figure out from the docs is how I am
supposed to achieve my goal, and be able to handle working variables
reliably within the assembly language block.Can anyone help?
Regards,
Steve
