If you use variable names instead of hard coding register numbers you don't have to worry about clobbering registers. For example, look at include/asm-ppc/atomic.h and you can find documentation of inline assembly at: http://gcc.gnu.org/onlinedocs/gcc-2.95.2/gcc_4.html#SEC93 -Frank -- Frank Rowand <frank_rowand at mvista.com> MontaVista Software, Inc ** Sent via the linuxppc-embedded mail list.
