[Bug target/14766] New: mips-sgi-irix6.5 testsuite failure in gcc.dg/overflow-1.c with -mabi=64

[ghazi at gcc dot gnu dot org]

Pretty much ever since the testcase gcc.dg/overflow-1.c was added to the 3.3.x 
branch testsuite, I've been seeing it fail on mips-sgi-irix6.5 with -mabi=64.  
Here's the first time I can find it:
http://gcc.gnu.org/ml/gcc-testresults/2003-12/msg00566.html
and it still occurs currently:
http://gcc.gnu.org/ml/gcc-testresults/2004-03/msg01481.html

I get:
overflow-1.c: In function `foo':
overflow-1.c:25: internal compiler error: in expand_simple_unop, at 
optabs.c:2328


To repeat the failure, target mips-sgi-irix6.5 and compile the following .i 
file with -O2 -S -mabi=64.  (You can use a cross-compiler.)

# 1 "overflow-1.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "overflow-1.c"
# 11 "overflow-1.c"
struct S {
  int key;
  int rnext,rprev;
};

void foo(struct S* H)
{
  int i, k;
  for (i=0; i<2; i++){
    struct S* cell=H+k;
    cell->key=i*(0xffffffffUL/2);
    cell->rnext=k+(1-i);
    cell->rprev=k+(1-i);
  }
}

I doubt that Jan's patch is likely to be backported to 3.3 so I think we can
resolve the bug with an "upgrade" or "wontfix" for 3.3.

Fine with me.  Then we should XFAIL it on the 3.3 branch at mabi=64.  I
don't have access to irix anymore (or any time for GCC at the moment) so I'd
very much appreciate it if someone would take care of this.  Thanks.

It's a legitimate failure, we don't often xfail those - even when there is a
known fix.

Huh?  It may be a legitimate failure, but you've decided not to fix it.  I
thought that's exactly what an XFAIL is for.

Everytime I try to guess what an XFAIL is for other than a "not implemented yet"
failure I get in trouble. I'm willing to go with this if the 3.3 branch manager
approves though (and I can figure out an easy way to conditionalize the failure
on -mabi=64).
