------- Comment #2 from rguenth at gcc dot gnu dot org 2008-09-08 12:21 -------
ANTIC_OUT[4] := { {view_convert_expr ,integer_cst 0} (0005) }
ANTIC_IN[4] := { {view_convert_expr ,integer_cst 0} (0005) }
S[4] := { {view_convert_expr ,integer_cst 0} (0005) }
so a quick look suggests we fail to properly fold references during PHI
translation.
<bb 4>:
bar_34 = 0;
<bb 5>:
# bar_11 = PHI <bar_33(7), bar_33(6), bar_34(4)>
dest.12_29 = VIEW_CONVERT_EXPR<float>(bar_11);
