------- Comment #10 from rguenth at gcc dot gnu dot org 2008-09-09 17:18 -------
And the reason for that is that re-gimplifying cvt.width hits
gimplify_var_or_parm_decl which will substitute cvt with its
DECL_VALUE_EXPR which is cvt.64. This is - unfortunate, because
we cannot easily fix that.
Looks like we have to add a new flag to gimplify_ctxp to avoid
this replacement for later gimplification of operands. We can
of course also disable scalarizing of variables with DECL_VALUE_EXPR,
but that doesn't look right.
Diego, any preferences?
