[RFAv4,2/3] Test the convenience functions $_gdb_setting and $_gdb_int_setting.
Commit Message
gdb/testsuite/ChangeLog
2019-09-07 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* gdb.base/setshow.exp: Test $_gdb_setting and $_gdb_setting_str.
* gdb.base/settings.exp: Test all settings types using
$_gdb_maint_setting and $_gdb_maint_setting_str in proc_show_setting,
that now verifies that the value of "maint show" is the same as
returned by the settings functions.
* gdb.base/default.exp: Update show_conv_list.
