[Bug middle-end/18582] New: Internal compiler error with arrays of type V2DF

[sbo at mis dot mpg dot de]

Using

  gcc -c ice.c

with the following file "ice.c"

  typedef double v2df __attribute__((mode(V2DF)));
  void
  sse_interpolate_kernel()
  {
    double x2[2];
    v2df xs[2];
    xs[0] = __builtin_ia32_loadupd(x2);
  }

leads to the following internal compiler error:

  ice.c: In function `sse_interpolate_kernel':
  ice.c:11: internal compiler error: in instantiate_virtual_regs_lossage, at
    function.c:3756
  Please submit a full bug report,

The error seems to disappear if I replace the array xs by simple variables or if
I use "-O".

: Search converges between 2003-01-27-trunk (#173) and 2003-02-03-trunk (#174).
: Search converges between 2003-01-28-3.3 (#19) and 2003-02-04-3.3 (#20).


Fixed on the mainline by the merge of the tree-ssa:
: Search converges between 2004-05-11-trunk (#454) and 2004-05-14-trunk (#455).
Fixed on the tree-ssa branch:
: Search converges between 2003-08-15-ssa (#58) and 2003-08-16-ssa (#59).

(note this does not make sense as usually the things are fixed by the tree-ssa when optimizing).
