I am not sure the underlying problem is fixed. The assembly language error
seems to come from the line:
.pred.rel.mutex p0, p1
p0 is a fixed predicate register and should never show up here. p1 is not used
in this program and due to the way GCC allocates predicate registers on IA64 I
don't think GCC can ever use p1.
The routine emit_predicate_relation_info in config/ia64/ia64.c looks at all
predicate registers to see if it should put out a pred.rel.mutex for them. I
wonder if it should even look at p0. We could have it start at p2 instead. But
maybe it would be better to understand why it thinks it needs a mutex for p0
in this case.

Almost the complete set of predicate registers is live throughout most of
function writet1, this looks bogus.

It looks like this is due to code in ia64/ia64.c (ia64_compute_frame_size).
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.
