The summary results are pretty obvious:

error)
FAIL: gcc.c-torture/execute/930921-1.c compilation,  -O2  (internal compiler

excess errors)

This are  __not__ the mayalias  failures which continue to fail with 4.3.0 and
are __not__
marked XFAIL

There is only on category, namely rs6000, both in the config tree and in the
MAINTAINERS LIST, so do expect the submitters to devine  any other name dujour.

Also if the supposedly scarce manpower available  can process hundreds of
pretty irrelevant GPL3 and whitespace elimination patches ( even for an already
released 4.2.x series) then submitters should not be harassed about submitting 
superfluous details.

GPL3 has been dismissed by the world. Just look at the trade press, slashdot,
dig, and others.

There is neither adequate management for the steering committee down nor other
than lip-service to quality control. This and recent submissions by the
Debian-gcc-team prove the point.

Just to gild the lily here goes:

#include <stdlib.h>
f (x)
     unsigned x;
{
  return (unsigned) (((unsigned long long) x * 0xAAAAAAAB) >> 32) >> 1;
}

main ()
{
  unsigned i;

  for (i = 0; i < 10000; i++)
    if (f (i) != i / 3)
      abort ();
  exit (0);
}
