(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. (is_gimple_reg_or_call_rhs): Rename to ... (is_gimple_reg_rhs_or_call): ... this. (is_gimple_mem_or_call_rhs): Rename to ... (is_gimple_mem_rhs_or_call): ... this. (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. (rhs_predicate_for): Remove formal temp case. (gimplify_modify_expr_rhs): Likewise. (gimplify_addr_expr): Use is_gimple_reg. (gimplify_expr): Remove formal temp cases. (gimple_regimplify_operands): Likewise. * tree-ssa-pre.c (get_or_alloc_expr_for): Treat EXC_PTR_EXPR and FILTER_EXPR like constants. * gimple.c (walk_gimple_op): Fix val_only initialization, use 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 the first operand of binary and comaprison expressions. * gcc.dg/tree-ssa/pr23401.c: New testcase. * gcc.dg/tree-ssa/pr27810.c: Likewise.
