This patch avoids multiple definitions of def_stmt in different
blocks, and moves it at
the beginning of gimple_match_and_simplify.
* genmatch.c (decision_tree::gen_gimple): Call fprintf to generate
definition of def_stmt.
(dt_operand::gen_gimple_expr): Adjust call to fprintf to generate
assignment of def_stmt.
Thanks and Regards,
