Set timeout for gdb.reverse/*.exp test cases
Hi, This patch is to add a new board setting gdb_reverse_timeout, which is used to set timeout for all gdb.reverse test cases, which are usually very slow and cause some TIMEOUT failures, for example, on some arm boards. We have some alternatives to this approach, but I am not satisfied with them: - Increase the timeout value. This is the global change, and it may cause some delay where actual failures happen. - Set timeout by gdb_reverse_timeout in every gdb.reverse/*.exp. Then, we have to touch every file under gdb.reverse. In this patch, we choose a central place to set timeout for all tests in gdb.reverse, which is convenient. gdb/testsuite: 2014-05-20 Yao Qi <yao@codesourcery.com> * lib/gdb.exp (gdb_init): Set timeout if test file is under gdb.reverse directory and gdb_reverse_timeout exists in board setting. * README: Document gdb_reverse_timeout.

+gdb_reverse_timeout

+Defining this variable changes the default timeout duration when tests
+under gdb.reverse directory are running. Process record and reverse
+debugging is so slow that its tests have unexpected `TIMEOUT' test
+failures. This global variable is useful to bump up the value of
+`timeout' for gdb.reverse tests and doesn't cause any delay where
+actual failures happen in the rest of the testsuite.
