If we need to store any predicate register (before a call I presume), the code stores them all and sets regs_ever_live[regno] to 1 for all predicate registers. There are question marks in the comment for this code. It looks like it was added in version 1.40 of ia64.c by rth. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21721
