Also ICEs on i686-pc-linux-gnu with -msse2.
The problem is again in:
--cut here--
rtx
expand_simple_binop (enum machine_mode mode, enum rtx_code code, rtx op0,
rtx op1, rtx target, int unsignedp,
enum optab_methods methods)
{
optab binop = code_to_optab[(int) code];
gcc_assert (binop);
return expand_binop (mode, binop, op0, op1, target, unsignedp, methods);
}
--cut here--
code_to_optab returns NULL for (unsupported) VEC_SELECT code. IIRC, we already
have some discussion about this issue.
The backtrace is:
