/* PR 5312

The problem here is that the ia64 scheduler saw a sequence of L L M type
|
3 |
|
|
insns, and messed up its internal state on which slot it was issuing
|
4 |
|
|
to, and aborted. */

/* { dg-do compile } */

/* In ILP32 mode, we get warnings about large integer constants.
|

|
|
Those cause spurious FAILs. */
