Although the construct below isn't valid (*ip++ and ip have to match because of the "0" constraint -- this is the result of only partly undoing a workaround for a bug in 1.31), the compiler should print a warning rather than dumping core. (This is both with and without optimization.) -- Ken ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ extern int i, *jp, j; foo () { volatile int *ip = jp; for (i=0; i < j ; i++) { asm volatile ("extzv %1,$1,%2,%0" : "g" (*ip++) : "g" (i), "g" (*jp), "0" (ip)); } } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
