[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.

Will not be fixed in 4.1.1; adjust target milestone to 4.1.2.

I cannot reproduce the reduced test case on a compiler built with:
../configure --target=powerpc-unknown-linux-gnuspe --enable-e500_double
and then the reduced testcase compiled like:
./cc1 t.c -mfloat-gprs=single -O2

This works for me on the mainline now, I just tried.

The original simd-3.c still fails on mainline (my test compiler is configured
with --enable-e500_double but it still appears with -mfloat-gprs=single) though
the reduced test doesn't.
