[Bug target/32342] New: [4.3 Regression] ICE in reload_cse_simplify_operands, at postreload.c:396

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I'm getting the following ICE on x86_64 with trunk.  I don't see this on
IA64.  It also worked with 4.3 20070604.

/home/tbm/filezilla-sshsh512.c: In function 'SHA512_Simple':

Please submit a full bug report,
with preprocessed source if appropriate.


Testcase:


typedef struct
{
  unsigned long hi, lo;
}
uint64;
typedef struct
{
  uint64 h[4];
}
SHA512_State;
SHA512_Core_Init (SHA512_State *s)
{
  static const uint64 iv[] = {
    {0x6a09e667, 0xf3bcc908},
    {0xbb67ae85, 0x84caa73b}
  };
  int i;
  for (i = 0; i < 4; i++)
    s->h[i] = iv[i];
}
SHA512_Simple (SHA512_State s)
{
  SHA512_Core_Init (&s);
  SHA512_Bytes (&s);
}
