arithmetic operations  on 128 bit integers (TI mode) on Apple G5 computers with macos X 10.3.5 
produce internal compiler error.


The program (buggcc341.c) is :

void main (void)
{
typedef unsigned __uint128_t __attribute__ (( __mode__ (__TI__)));
 __uint128_t x,a,w;
 x=a*w+a-w/a; 
}

The intermediaire file (buggcc341.i) is : 

# 1 "buggcc341.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "buggcc341.c"
void main (void)
{
typedef unsigned __uint128_t __attribute__ (( __mode__ (__TI__)));
 __uint128_t x,a,w;
 x=a*w+a-w/a;
}

On the platforms where such types might actually work, GCC provides 
built-in __int128_t and __uint128_t typedefs.  But:

(a) In any case, GCC should not give an internal compiler error.

(b) These types are never currently extended integer types within the 
meaning of C99 (see the documentation of implementation-defined behavior 
on mainline), although they may act quite similarly to such types.

Hmm, I think this is a regression but I could be wrong, the problem is that we semi-support TI mode 
on powerpc-darwin but only -mpowerpc64.

Why I said semi is because we don't impement the libgcc part of the functions which would be easy to 
add.

If I compile the option -mpowerpc64, gcc compiles my code.

If I compile without the option -mpowerpc64, gcc reports an internal error (instead of reporting an 
error on the type __int128_t )

Fixed in 3.4.3, we reject it:
t.c: In function 'main':
t.c:3: error: unable to emulate 'TI'

But if we don't do the typedef we still get an error:
t.c:4: internal compiler error: in expand_mult, at expmed.c:3001

This is a 3.4/4.0 regression as before HOST_WIDE_INT was not 64bits.

This is invalid code and I have no interesting in back porting the whole infrastructure to 3.4.x so I am 
closing as fixed for 4.0.0.
