Update.
2003-03-27 David Mosberger <davidm@hpl.hp.com> * sysdeps/ia64/dl-machine.h (RTLD_START): Wrap ".save rp, r0" directive into empty .prologue region to ensure that call-chain is terminated even for the first instruction. * sysdeps/ia64/elf/start.S (_start): Use ".save rp, r0" idiom to terminate call-chain right from the get-go. * sysdeps/unix/sysv/linux/ia64/fork.S (fork): Remove unnecessary stop bit between compare & branch.
