What's wrong with "ci" variable? It's just another register.
well the idea is that "ci" variable is just there as a tmp variable just
used in this asm code, right.
so why not simply get rid of its declaration (btw save a line of code ;-))
and just use a common temporay reg as r19?
No - don't do that. Let the compiler do the work of allocating registers.
It's really good at it. :) Much better than you and I combined. :)
You and gcc already prove it to me ;-)
All we need to do is tell the compiler we need a register.
Ok
Taken also into account of David remarks, here is the latest stuff tested with success:
__asm__ __volatile__ (
"lci %%r0(%%sr1, %2), %0\n"
"\textru %0,19,12,%0\n"
"\tdepw %0,15,12,%1\n"
: "=r" (ci), "=r" (pa)
: "r" (vba)
);
Tx to all for kind comments, they learn me a lot ;-)
J.
cheers,
grant
