[Bug c/24137] New: __uint128_t missing for ppc32

With following file (x.c):

main()
{
__uint128_t x;
printf("%d %p\n", sizeof(x), &x);
}

the compiler produces

Thanks for the quick response, but I think this support should be in ppc32 
compilers also. The altivec memory operations deal with 128-bit, 16-byte 
aligned values, and hence this support should be in ppc32.

The bug originally showed up in glibc 
sysdeps/unix/sysv/linux/powerpc/sys/procfs.h (line 57 for version 2.3.5), 
which includes a comment that __uint128_t has been around since gcc 3.1.

I still am not sure I agree, but I have read your post ( 
http://gcc.gnu.org/ml/gcc/2005-01/msg00514.html ) and since this appears to be 
an old issue I will go ahead and patch glibc for now.

Again thanks for the quick response, even if we disagree!
