Hi Dave,

It's great to hear from you.  It's been a long while.

Sorry, doh! yes, there's a mistake in my patch (that I introduced when I
the operands in the shd's define_expand to be the more logical 0, 1, 2, 3,
then 4).
Sorry for the inconvenience [due to my lack of familiarity with PA-RISC
Hopefully you should get much better mileage out of the attached revision.

Thanks again (and my sincere apologies),

This may be totally unrelated to this patch but I hit this error in stage2
testing your change:
build/genattrtab ../../gcc/gcc/common.md ../../gcc/gcc/config/pa/pa.md
insn-conditions.md \
        -Atmp-attrtab.c -Dtmp-dfatab.c -Ltmp-latencytab.c
genattrtab: Internal error: abort in attr_alt_union, at genattrtab.c:2383

It's great that you are back helpting with the middle-end.
