I've been meaning to commit just such a macro <sys/cdefs.h> to fix a
similar issue elsewhere. Something along the lines of:
#define __reorder_barrier() __asm __volatile("":::"memory")
If there are no objections, I'll go ahead and do this.
Since it prevents instruction reordering, I guess __insn_barrier() is better. Provide a means for <machine/cdefs.h> to override it, so SPARC can continue using it's no-memory-clobber version.
