Implemented change as per #10 on i686 and it appears to cure the problem.

No idea about darwin, cris-axis-elf, or other 32-bit.

Thanks Mr Berlin!

I already submitted a patch for this (see my followup to HP that fixes
valid_gimple_expression_p).
As soon as i can bootstrap on darwin, i will commit it.
If someone wants to do so before me, all you need to do is change
is_gimple_addressable to is_gimple_id in valid_gimple_expression_p

I already submitted a patch for this (see my followup to HP that fixes
valid_gimple_expression_p).
As soon as i can bootstrap on darwin, i will commit it.
If someone wants to do so before me, all you need to do is change
is_gimple_addressable to is_gimple_id in valid_gimple_expression_p

valid_gimple_expression_p claims
&((struct RegisterLayout *) (char *) &SimulatedRegisters)->intmask;

is valid GIMPLE, when it is not.

Note the testsuite already have a testcase for this issue as
g++.dg/opt/pr24665.C :).  Actually look at that, this bug is about that
testcase :).

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;
