------- Comment #2 from tbm at cyrius dot com  2007-09-07 14:11 -------
Here's a smaller testcase:

tbm@meitner:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O mxb.c
mxb.c: In function 'mxb_probe':
mxb.c:30: error: unrecognizable insn:
(insn 10 9 11 3 mxb.c:29 (parallel [
            (set (mem/s/j/c:QI (reg:SI 98) [0 D.1580.name+8 S1 A64])
                (const_int 0 [0x0]))
            (clobber (reg:SI 99))
            (clobber (reg:SI 100))
            (use (const_int 40 [0x28]))
            (use (const_int 8 [0x8]))
        ]) -1 (nil))
mxb.c:30: internal compiler error: in extract_insn, at recog.c:1990
Please submit a full bug report,


Testcase:

struct pci_device_id {
  unsigned long driver_data;
};

extern struct module __this_module;
  struct i2c_adapter {
  char name[48];
};

struct saa7146_dev;
struct saa7146_pci_extension_data {
  struct saa7146_extension *ext;
  void *ext_priv;
};
struct saa7146_extension {
 int (*probe)(struct saa7146_dev *);
}
input_port_selection[4] = {
    0x00, 0x00
};
struct mxb {
  struct i2c_adapter i2c_adapter;
};
static struct saa7146_extension extension;
static int mxb_probe(struct saa7146_dev* dev) {
  struct mxb* mxb = ((void *)0);
  mxb->i2c_adapter = (struct i2c_adapter) {
    .name = "mxb",
  };
}
static struct saa7146_pci_extension_data mxb = {
  .ext = &extension,
};
static struct pci_device_id pci_tbl[] = {

    .driver_data = (unsigned long)&mxb,
