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.
