From cbba3ecd36f0f861e4e810fbd5415c9759080cdc Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 13 Jun 2019 00:06:52 +0100 Subject: 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. (check_for_argument): Skip spaces after argument. --- gdb/cli/cli-cmds.c | 3 --- gdb/cli/cli-utils.c | 3 +-- gdb/cli/cli-utils.h | 4 +++- 3 files changed, 4 insertions(+), 6 deletions(-) (limited to 'gdb/cli') diff --git a/gdb/cli/cli-cmds.c b/gdb/cli/cli-cmds.c index 5c44ba9..62f4d7f 100644 --- a/gdb/cli/cli-cmds.c +++ b/gdb/cli/cli-cmds.c @@ -1381,9 +1381,6 @@ apropos_command (const char *arg, int from_tty) { bool verbose = arg && check_for_argument (&arg, "-v", 2); - if (verbose) - arg = skip_spaces (arg); - if (arg == NULL || *arg == '\0') error (_("REGEXP string is empty")); diff --git a/gdb/cli/cli-utils.c b/gdb/cli/cli-utils.c index c8b07f0..a24fe92 100644 --- a/gdb/cli/cli-utils.c +++ b/gdb/cli/cli-utils.c @@ -139,7 +139,6 @@ extract_info_print_args (const char **args, /* Check for NAMEREGEXP or -- NAMEREGEXP. */ if (**args != '-' || check_for_argument (args, "--", 2)) { - *args = skip_spaces (*args); *regexp = *args; *args = NULL; return true; @@ -155,7 +154,6 @@ extract_info_print_args (const char **args, if (check_for_argument (args, "-q", 2)) { *quiet = true; - *args = skip_spaces (*args); return true; } @@ -459,6 +457,7 @@ check_for_argument (const char **str, const char *arg, int arg_len) && ((*str)[arg_len] == '\0' || isspace ((*str)[arg_len]))) { *str += arg_len; + *str = skip_spaces (*str); return 1; } return 0; diff --git a/gdb/cli/cli-utils.h b/gdb/cli/cli-utils.h index d0161db..9425fb4 100644 --- a/gdb/cli/cli-utils.h +++ b/gdb/cli/cli-utils.h @@ -188,7 +188,9 @@ extern std::string extract_arg (const char **arg); /* A helper function that looks for an argument at the start of a string.
