The regression in 10681 was introduced or exposed by this patch:

2003-04-25  Richard Henderson  <rth@redhat.com>

        * config/ia64/ia64.c (ia64_compute_frame_size): Allow inline asm
        to clobber ar.pfs and ar.unat.
        (ia64_expand_prologue): Force alloc instruction if ar.pfs saved;
        fix test for spilling ar.pfs to the stack.

The hunt used the submitter's test case, compiled with -O2 using a cross       
cc1 with host i686-pc-linux-gnu, target ia64-linux.
