From 195bcdd5183f2c137399db23a68a26a4e4193f8f Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 29 Jun 2017 15:52:37 +0100 Subject: [PATCH] Remove old stale expression_completer hack The code in question was introduced by: https://sourceware.com/ml/gdb-patches/2008-06/msg00143.html "The fix is to make sure that the entire expression is passed to expression_completer, then duplicate some logic there in the case where location_completer is called." The logic that was duplicated was much later on removed by the original explicit locations patch: commit 87f0e7204722a986f79f245eee716f0870832d47 Author: Keith Seitz AuthorDate: Tue Aug 11 17:09:36 2015 -0700 Commit: Keith Seitz CommitDate: Tue Aug 11 17:09:36 2015 -0700 Explicit locations: add UI features for CLI @@ -688,16 +880,6 @@ complete_line_internal (const char *text, rl_completer_word_break_characters = gdb_completer_file_name_break_characters; } - else if (c->completer == location_completer) - { - /* Commands which complete on locations want to - see the entire argument. */ - for (p = word; - p > tmp_command - && p[-1] != ' ' && p[-1] != '\t'; - p--) - ; - } However this case in expression_completer was left behind.
