With following file (x.c):
main()
{
__uint128_t x;
printf("%d %p\n", sizeof(x), &x);
}
the compiler produces

__uint128_t is only valid for 64bit targets. Otherwise you will get an ICE trying to use the type.

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.

This is a bug in glibc.

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!

------- Comment #5 from janis187 at us dot ibm dot com 2005-10-07 20:27 -------
I bumped into this PR by accident and happen to have looked into this recently.
__uint128_t is supported on a ppc64 system with a powerpc64-linux compiler
using "-m32 -mpowerpc64".
