Since I don't have access to an irix box anymore I'd really need the
instruction it fails on at the least, some annotated assembly would be a good
start (compile the failing file with -dap and attach the .s output).

Created an attachment (id=10097)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=10097&action=view)
assembler output

I compiled c-parser.c with the exact same commandline as in the bootstrap,
except the added -S -dap switch. Output as attachment.
Additionally I tried to change the -O2 switch to -O1, wich failed too.
Compilation without optimization switch succeeds. If helpfull in any way, I may
provide the output of these compilations too.

The patch to 23585 is likely the cause.

Changing to P1 since it's a regression that likely affects all mips (including
primary platform mips-elf).

I don't know if it is allowed for someone to change the priority (except to P3
so that Mark can relook at the bug).

I'm going to make this a P2.  IRIX isn't a primary platform anymore.  Thanks,

Oh, this effects mips-elf also which is a primary target.

It is failing in:
285               return offset % GET_MODE_SIZE (mode) != 0;
mode is BLKmode which has a mode size of 0.

The RTL which is failing:
(set (reg:DI 2 $2 [197])
    (unspec:DI [
            (mem/s/c:BLK (plus:DI (reg/f:DI 29 $sp)
                    (const_int 8 [0x8])) [0+4 S8 A32])
            (mem/s/c:QI (plus:DI (reg/f:DI 29 $sp)
                    (const_int 8 [0x8])) [0+4 S1 A32])
        ] 18))


I don't even know what this instruction does but it is a MIPS specific issue.

------- Comment #15 from pinskia at gcc dot gnu dot org  2005-11-03 14:43 -------
I think this is fixed now by:
        PR rtl-optimization/23585
        * rtlanal.c (rtx_addr_can_trap_p_1) <PLUS>: Return 0 for an address
        that can't trap plus a constant integer, if the mode has zero size.

Can you try again with today's compiler (or do you need to wait for a
snapshot?)

Or you could try the patch in
http://gcc.gnu.org/ml/gcc-patches/2005-11/msg00103.html

Sorry, for the delay.
I had a machine fault on the weekend.
So, I'm trying the snapshot from 5th of november now!
Look's good so far, already in stage 2.

This is good enough to close this as fixed.  Thanks.
