------- Comment #4 from rguenth at gcc dot gnu dot org 2008-01-21 13:54 -------
And for_each_index does not handle CONSTRUCTOR. Then, we ICE in
copy_reference_ops_from_ref, at tree-ssa-sccvn.c:574
because that obviously also does not handle CONSTRUCTOR either.
_Then_, at -O2, we ICE in simplify_immed_subreg (x86_64 -m32 -msse)
#1 0x000000000085ed6b in simplify_immed_subreg (outermode=V16QImode,
op=0x2ae82bd7b6b0, innermode=V4SImode, byte=0)
at /space/rguenther/src/svn/trunk/gcc/simplify-rtx.c:4761
4761 gcc_unreachable ();
(gdb) call debug_rtx (op)
(const_vector:V4SI [
(const:SI (plus:SI (symbol_ref:SI ("g") [flags 0x40] <var_decl
0x2ae82c6450a0 g>)
(const_int 32 [0x20])))
(const_int 0 [0x0])
(const_int 0 [0x0])
(const_int 0 [0x0])
])
as we don't handle a const:SI wrapped first vector element. I'm going to
"fix" the non-rtl cases.
