[Bug target/27565] New: [4.1/4.2 Regression] ICE in assign_stack_temp_for_type for vectors with SPE

[jsm28 at gcc dot gnu dot org]

Many GCC tests such as gcc.c-torture/compile/simd-3.c fail on
powerpc-none-eabispe with an ICE in assign_stack_temp_for_type.  This happens
with trunk and 4.1 branch but not with 4.0 branch.  Reduced testcase:

typedef double V __attribute__((vector_size (16)));

void f(void)
{
  volatile V t = { 0.0, 0.0 };
}

t.c: In function 'f':
t.c:5: internal compiler error: in assign_stack_temp_for_type, at
function.c:716
Please submit a full bug report,
with preprocessed source if appropriate.
