	* tree.h (DECL_GIMPLE_FORMAL_TEMP_P): Remove.
	(struct tree_decl_with_vis): Remove gimple_formal_temp member.
	* tree-eh.c (lower_eh_constructs_2): Move LHS assignment to
	a separate statement.
	* gimplify.c (pop_gimplify_context): Remove formal temp handling.
	(lookup_tmp_var): Likewise.
	(is_gimple_formal_tmp_or_call_rhs): Remove.

	(internal_get_tmp_var): Use is_gimple_reg_rhs_or_call.  Set
	DECL_GIMPLE_REG_P only if is_formal is true.
	(gimplify_compound_lval): Use is_gimple_reg.  Remove workaround
	for non-proper post-modify expression gimplification.
	(gimplify_self_mod_expr): For post-modify expressions gimplify
	the lvalue to a minimal lvalue.

	(gimplify_addr_expr): Use is_gimple_reg.
	(gimplify_expr): Remove formal temp cases.

	is_gimple_reg.
	(is_gimple_formal_tmp_rhs): Remove.
	(is_gimple_reg_rhs): Remove special casing.
	(is_gimple_mem_rhs): Fix.
	(is_gimple_reg): Move DECL_GIMPLE_REG_P handling earlier.
	(is_gimple_formal_tmp_var): Remove.
	(is_gimple_formal_tmp_reg): Likewise.
	(is_gimple_min_lval): Allow invariant component ref parts.
	* gimple.h (is_gimple_formal_tmp_rhs, is_gimple_formal_tmp_var,
	is_gimple_formal_tmp_reg): Remove declarations.
	* tree-cfg.c (verify_expr): Verify that variables with address
	taken do not have DECL_GIMPLE_REG_P set.
	* tree-mudflap.c (mf_build_check_statement_for): Use
	force_gimple_operand instead of gimplify_expr.

	java/
	* java-gimplify.c (java_gimplify_expr): Do not manually gimplify
