As of SVN version 110852, I cannot bootstrap IA64 HP-UX compiler. The compiler
dies while compiling tree-into-ssa.c. I have a preprocessed cut-down version
of this file that I will attach to this defect. I proposed a workaround/patch
earlier, it is at http://gcc.gnu.org/ml/gcc-patches/2006-02/msg01288.html. But
that patch is a workaround for the real bug, loosing the POINTER attribute on
the register. The attached program compiles with -O2 -fno-move-loop-invariants
but dies with an unrecognized instruction with -O2. The failure is I get is
below, the instruction is not regognized because reg 385 is not marked as a
ponter.
x.c:122: error: unrecognizable insn:
(insn 76 68 135 3 (set (reg:DI 387)
(unspec:DI [
(plus:SI (subreg/s/v:SI (reg:DI 385) 4)
(const_int 4 [0x4]))
] 24)) -1 (insn_list:REG_DEP_TRUE 142 (nil))
(expr_list:REG_DEAD (reg:DI 385)
(expr_list:REG_EQUAL (unspec:DI [
(plus:SI (subreg/s/v:SI (reg:DI 385) 4)
(const_int 4 [0x4]))
] 24)
(nil))))
x.c:122: internal compiler error: in extract_insn, at recog.c:2075

I don't know how I missed your proposed patch for PR 19061. I tested it on the
test case in that bug and on my bootstrap bug that I reported here and both
look good. I used ToT sources for both tests and had to put your change in
predicates.md instead of ia64.c but it looks good to me. I can do a full
bootstrap if you want me to, I think we should try and get this into 4.1 as
well as ToT if possible.

Great! My (limited) understanding is that it will pessimize the code a little,
but that was deemed acceptable by the PA back-end so...

I'm not really in position to do any testing for 4.x on IA-64/HP-UX at the
moment, so it's up to you.
