+
+ * gdb.base/foll-exec.c: Add copyright header. Fix
+ formatting issues.
+ * gdb.base/foll-exec.exp (zap_session): Delete proc.
+ (do_exec_tests): Use clean_restart in place of zap_session,
+ and for test initialization. Fix formatting issues. Use
+ fail in place of perror.
+ * gdb.base/pie-execl.exp (main): Use 'inferior_spawn_id' in
+ an expect statement to match an expression with output from
+ the program under debug.
+ * gdb.threads/non-ldr-exc-1.exp (do_test, main): Add
+ non-stop tests and use save_vars to enable non-stop in GDBFLAGS.
+ * gdb.threads/non-ldr-exc-2.exp: Likewise.
+ * gdb.threads/non-ldr-exc-3.exp: Likewise.
+ * gdb.threads/non-ldr-exc-4.exp: Likewise.
+
2015-09-09 Doug Evans <dje@google.com>
* gdb.python/py-prettyprint.exp: Check result of run_lang_tests.
