[Bug c/32693] New: [H8] : ICE: in gen_rtx_SUBREG, at emit-rtl.c:693

Hi,

Compiling following testcase for "h8sx" target with optimization (-O1
onwards), gives ICE (internal compiler error) . The testcase works fine
for other H8 targets.


// Start Of Testcase

=======================================================================

#include <stdlib.h>

typedef union
{
        unsigned long LONG;
        struct
        {
                unsigned long Year : 14,
                                  Month : 18;
        } Bit;
} test;

typedef struct
{
        unsigned int year ;
} Date;

unsigned int foo(Date *ptr_Date)
{
        Date obj_Date;
        test obj_test;

        obj_test.LONG = 2000;
        obj_Date.year = (unsigned int)obj_test.Bit.Year;

        if(ptr_Date!=NULL) *ptr_Date=obj_Date;
        return(0);
}

=======================================================================

// End Of Testcase
