[Bug tree-optimization/32746] [4.3 Regression] tree-ssa-operands int.comp error

------- Comment #2 from pinskia at gcc dot gnu dot org  2007-07-13 02:26 -------
Reduced testcase:
struct RegisterLayout
{
    int intmask;
};
struct Controller_t
{
    static inline void
    disableInterrupt()
    {
        *mpMaskRegister = 0;
    };
    static int * const mpMaskRegister;
};
extern char SimulatedRegisters[];
int * const Controller_t::mpMaskRegister
  = &((RegisterLayout*)SimulatedRegisters)->intmask;
void f()
{
   Controller_t::disableInterrupt();
}


-----  CUT -----
FRE is where it goes wrong:
  mpMaskRegister.0_1 = &((struct RegisterLayout *) (char *)
&SimulatedRegisters)->intmask;
