            Bug ID: 60506
           Summary: g++ reports "internal compiler error" using SSE2 and
                    not entirely beautiful programming
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jenkinsj89 at yahoo dot ca
              Host: i86_64-pc-cygwin
            Target: i86_64-pc-cygwin -march=corei7

I compiled the enclosed program with:

g++ -S -v -Wall -Wextra -std=c++11 -march=corei7 -save-temps rabbit-gccbug.cc

and it reported the text hereafter pasted.  It reports the same error
if "-O2" is enabled, and it also reports the same error if 
"-fno-strict-aliasing -fwrapv -fno-aggressive-loop-optimizations"
is provided.

As requested, I am attaching the preprocessed output rather than the original
program, but please note that the only included file is <cstdint>.

Reduced testcase:
typedef unsigned QuadV4 __attribute__((vector_size(16)));
void updateCount() {
QuadV4 QZ;
QuadV4 v;
v == QZ && v == QZ;
}

ICEs as of 4.9 20140219 too.

C front-end errors out:
t.c: In function ‘updateCount’:
t.c:5:5: error: used vector type where scalar is required

Turns out this is dup of bug 58845.  In 4.9 we print a sorry message meaning we
don't handle this just yet.
