From e2a689da55d3feb7b79a141f69c4049112f59c91 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 13 Jun 2019 00:06:53 +0100 Subject: [PATCH] lib/completion-support.exp: Add test_gdb_completion_offers_commands This adds a procedure to the collection of completion-testing routines, that allows checking whether completion offers all commands as completion candidates. This will be used for testing completing "frame apply all [TAB]", "thread apply all [TAB]", etc. gdb/testsuite/ChangeLog: 2019-06-13 Pedro Alves * lib/completion-support.exp (test_gdb_complete_tab_multiple) (test_gdb_complete_cmd_multiple, test_gdb_complete_multiple): Add 'max_completions' parameter and handle it.
