From 560ee2158d17212ecb2ec282ee15b1e1eb5f2092 Mon Sep 17 00:00:00 2001 From: Davi Arnaut Date: Wed, 20 Oct 2010 16:21:40 -0200 Subject: Bug#45288: pb2 returns a lot of compilation warnings Fix assorted warnings that are generated in optimized builds. Most of it is silencing variables that are set but unused. This patch also introduces the MY_ASSERT_UNREACHABLE macro which helps the compiler to deduce that a certain piece of code is unreachable. --- sql/sql_union.cc | 9 --------- 1 file changed, 9 deletions(-) (limited to 'sql/sql_union.cc') diff --git a/sql/sql_union.cc b/sql/sql_union.cc index 948ba1d9d9c..70598fbfcd4 100644 --- a/sql/sql_union.cc +++ b/sql/sql_union.cc @@ -173,7 +173,6 @@ bool st_select_lex_unit::prepare(THD *thd_arg, select_result *sel_result, SELECT_LEX *sl, *first_sl= first_select(); select_result *tmp_result; bool is_union_select; - TABLE *empty_table= 0; DBUG_ENTER("st_select_lex_unit::prepare"); describe= test(additional_options & SELECT_DESCRIBE); @@ -275,14 +274,6 @@ bool st_select_lex_unit::prepare(THD *thd_arg, select_result *sel_result, types= first_sl->item_list; else if (sl == first_sl) { - /* - We need to create an empty table object.
