enable-checking problems on PPC

[Franz Sirl <Franz dot Sirl-kernel at lauterbach dot com>]

Hi,

I have some problems building GCC with --enable-checking on Linux/PPC. I was
able to tackle 2 problems myself with the appended minor patches (please
comment), but I can't find a solution for my current problem, this
code compiled wit -O2 -fPIC:

typedef          int SItype     __attribute__ ((mode (SI)));
typedef unsigned int USItype    __attribute__ ((mode (SI)));
typedef          int DItype     __attribute__ ((mode (DI)));
typedef unsigned int UDItype    __attribute__ ((mode (DI)));
typedef         float DFtype    __attribute__ ((mode (DF)));

DFtype
__floatdidf (DItype u)
{
  DFtype d;

  d = (SItype) (u >> (sizeof (SItype) * 8 ) );
  d *= (((UDItype) 1) << ((sizeof (SItype) * 8 )  / 2)) ;
  d *= (((UDItype) 1) << ((sizeof (SItype) * 8 )  / 2)) ;
  d += (USItype) (u & ((((UDItype) 1) << (sizeof (SItype) * 8 ) )  - 1));

  return d;
}

aborts with:
checking_bug.c: In function `__floatdidf':
checking_bug.c:19: RTL check: expected elt 0 type 'e' or 'u', have 's' (rtx symbol_ref)
checking_bug.c:19: Internal compiler error in `decode_rtx_const', at varasm.c:3358

I can't seem to find a valid solution for that one, and maybe it's a bug
earlier in the compiler. Any hints?

Franz.
