From cbba3ecd36f0f861e4e810fbd5415c9759080cdc Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 13 Jun 2019 00:06:52 +0100 Subject: [PATCH] Make check_for_argument skip whitespace after arg itself Basically every caller of check_for_argument needs to skip space after the argument. This patch makes check_for_argument do it itself. Suggested by Philippe Waroquiers. gdb/ChangeLog: 2019-06-13 Pedro Alves * ax-gdb.c (agent_command_1): Remove skip_spaces call. * breakpoint.c (watch_maybe_just_location): Remove skip_spaces call. * cli/cli-cmds.c (apropos_command): Remove skip_spaces call. * cli/cli-utils.c (extract_info_print_args): Remove skip_spaces calls.
