--- Comment #3 from kugan at gcc dot gnu.org ---
correction:
with 4.9 when it ICE we have:
Breakpoint 1, expand_fix (to=to@entry=0x7ffff65b5480, from=0x7ffff65b2000,
unsignedp=unsignedp@entry=0) at
/home/kugan/work/sources/gcc-fsf/4.9/gcc/optabs.c:5206
5206 {
(gdb) p debug_rtx (from)
(reg:V4SI 155 [ vect_vec_iv_.19 ])
$23 = void
(gdb) p debug_rtx (to)
(reg:V4SI 281)
$24 = void
with trunk when it is working:
Breakpoint 1, expand_fix (to=to@entry=0x7ffff64a7ac8, from=0x7ffff64a7a98,
