[Bug optimization/13525] New: ICE on valid code.

[tm at kloo dot net]

When compiling using the options -O2 -m4 -fnew-ra -S, GCC crashes on almost
every file in stress-1.17:

./aiunit.i:5631: internal compiler error: in remember_move, at ra-build.c:579
./advdomestic.i:3820: internal compiler error: in remember_move, at
ra-build.c:579
./advmilitary.i:3944: internal compiler error: in remember_move, at
ra-build.c:579
./attsub.i:12800: internal compiler error: in remember_move, at ra-build.c:579
./avl.i:1720: internal compiler error: in remember_move, at ra-build.c:579
./avltr.i:2706: internal compiler error: in remember_move, at ra-build.c:579
./blitcursor.i:19374: internal compiler error: in remember_move, at
ra-build.c:579
...

It appears to be failing a sanity check in new-ra:

          /* Some sanity test for the copy insn.  */
          struct df_link *slink = DF_INSN_USES (df, insn);
          struct df_link *link = DF_INSN_DEFS (df, insn);
          if (!link || !link->ref || !slink || !slink->ref) <- line 578
            abort ();

Confirmed with new-ra cvs (20031009 is what it claims to be but I checked it out
this morning).
