             Bug #: 54193
           Summary: dump_gimple_assign raw can't handle 4 operands
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: glisse@gcc.gnu.org


#include <x86intrin.h>

__m128d
f (__m128d x)
{
  __m128i m = {0, 1};
  return __builtin_shuffle (x, m);
}

$ gcc sh.c -c -fdump-tree-optimized-raw
sh.c: In function 'f':
sh.c:4:1: internal compiler error: in dump_gimple_assign, at
gimple-pretty-print.c:485
 f (__m128d x)
 ^
Please submit a full bug report,

which is fairly natural with code like:

      if (gimple_num_ops (gs) == 2)
        last = NULL_TREE;
      else if (gimple_num_ops (gs) == 3)
        last = gimple_assign_rhs2 (gs);
      else
        gcc_unreachable ();

(the non-raw version below goes up to 4)

I guess the -raw option doesn't see much use these days. I was trying it
because sometimes it isn't obvious what tree code is meant by the C-like
representation.
