I get an internal compiler error when compiling the code below. The compiler
error goes away if the "-fno-tree-ccp" is added to the command line. The exact
error message is:
gccbug.cpp: In constructor 'Controller_t::Controller_t()':
gccbug.cpp:41: internal compiler error: in get_indirect_ref_operands, at
tree-ssa-operands.c:1453
This is not a duplicate of #21167. That patch already appears to be in 4.0.2.
The "-v" option gives this configuration:
Using built-in specs.
Target: powerpc-603e-eabi
Configured with: /c/GCC/src/gcc-4.0.2/configure --target=powerpc-603e-eabi

/c/DOCUME~1/djohnson/LOCALS~1/Temp/cckcPKQy.s
The exact code that generates this error is:
------------------
// Compile with -O2.
// compiler error goes away if "-fno-tree-ccp" is added
typedef unsigned long uint32_t;
// compiler error goes away if "const" is removed
typedef volatile uint32_t* const hwreg_t;
struct RegisterLayout
{
uint32_t intmask;
};
struct Controller_t
{
public:
Controller_t();
inline void
disableInterrupt()
{
*mpMaskRegister = 0;
};
static hwreg_t mpMaskRegister;
};
extern char SimulatedRegisters[];
// compiler error goes away if "volatile" is remove
#define MACHINE \
(reinterpret_cast<volatile RegisterLayout*>(SimulatedRegisters))
hwreg_t Controller_t::mpMaskRegister = &MACHINE->intmask;
Controller_t::Controller_t()
{
disableInterrupt();
}

------- Comment #1 from pinskia at gcc dot gnu dot org 2005-11-04 05:06 -------
Confirmed, reduced testcase as far as I can get it (and is willing to try at
this point):
typedef unsigned long uint32_t;
typedef volatile uint32_t* const hwreg_t;
struct RegisterLayout
{
uint32_t intmask;
};
struct Controller_t
{
Controller_t();
inline void
disableInterrupt()
{
*mpMaskRegister = 0;
};
static hwreg_t mpMaskRegister;
};
extern char SimulatedRegisters[];
hwreg_t Controller_t::mpMaskRegister = &(reinterpret_cast<volatile
RegisterLayout*>(SimulatedRegisters))->intmask;
Controller_t::Controller_t()
{
disableInterrupt();
}

Something is not gimplifing an expression:
*(struct RegisterLayoutD.2065 *) (charD.3 *) &SimulatedRegistersD.2082
------
# SimulatedRegistersD.2082_6 = V_MAY_DEF <SimulatedRegistersD.2082_5>;
((struct RegisterLayoutD.2065 *) (charD.3 *)
&SimulatedRegistersD.2082)->intmaskD.2067 = 0
CCP it looks like.

Lattice value changed to CONSTANT &((struct RegisterLayout *) (char *)
&SimulatedRegisters)->intmask. Adding SSA edges to worklist.
Substituing values and folding statements
Folded statement: mpMaskRegister.0_4 = mpMaskRegister;
into: mpMaskRegister.0_4 = &((struct RegisterLayout *) (char *)
&SimulatedRegisters)->intmask;
